A customer reached out to Support about inconsistent arrival times on stacks using his ES-3000. After stepping through the set up, he sent the .dat files for us to look into. It was mentioned that the seismograph itself is not capable of randomly triggering early and that there was something external to the instrument causing this 100-200mS early trigger event to occur. Another puzzling factor was that it occurred randomly after a number of shots in auto-stack mode (10). It took some investigating and convincing, but what was finally concluded that the sledgehammer in use had some "flex" in the handle that would cause a "pre-trigger" on the downswing. Once the hammer was replaced the pre-triggers ceased.   Thanks again for the time on the phone today. I really appreciate the guidance and experience of your team.   After the discussion with your team, this led me to do a few more tests on the equipment. This evening, I got 40 stacks with no inconsistency in arrival times.   To close the loop on what I think was going on: I believe the hammer itself may have been the issue, husky hammers have a shock absorber and a sloped handle. Having the trigger strapped in a particular way on the hammer may have been the cause here. See image below:   Attachment : Husky Hammer.png   I used a new hammer (NOT HUSKY) and did not experience the inconsistent arrival times. I will continue to monitor the issue. I appreciate the Support from your team! I've individually swapped out all other components (aside from the geode) - this is the only change that seems to have solved the issue.   In summary: My theory is either the shock absorber, or sloped handle caused the trigger to delay, resulting in early arrival times.

Attachment : Bulletin_Good Practice-Charging the Atom.V1.pdf This bulletin is written to inform those customers who purchased the ATOM 1C and 3C seismographs (“Atoms”), to allow for out gassing and temperature cooling when charging the batteries. Background: Geometrics has noted that some users use fitted cases for their Atoms to allow for safe shipping and handling between deployments. If the Atoms are fitted with charging cables and are being charged while inside the fitted cases, under certain circumstances, the fitted cases may not allow for sufficient air circulation and could lead to excessive temperatures inside the Atom unit. These excessive temperatures can exceed the battery manufacturers suggested safe charging temperature, resulting in some instances in out-gassing of hydrogen during the charging process. Recommendation: Geometrics recommends that users remove their Atom unit(s) from any enclosed/insulated boxes (including fitted cases) prior to charging. Each Atom unit requires adequate surface to air access for heat dissipation. We also recommend that users do not leave the Atom unit on charge for long periods of time. Geometrics recommends that a typical maximum charge time should not exceed 12-15 hours. Precautionary Steps: In addition to using good practice charging as we have described in this Bulletin, Geometrics will provide users a procedure for installing a GORE® Protective Vent to allow for the release of pressure and gas from inside the fitted case housing should such pressure and gas accumulate. These vents can be installed at local service centers or at Geometrics factory. Please contact our Geometrics Support organization at for additional information.

Dead-Zones The MagArrow is a dual sensor magnetometer powered by MFAM sensors, but it is configured for use so it only has a single data output. The reason Geometrics has done this is so we could ensure the MagArrow encounters no "dead-zones". A dead-zone occurs when the orientation of a magnetometer results in the magnetometer producing poor or no measurements. The dead-zone angle depends on the location of survey. Since we have the two MagArrow MFAM sensors in orthogonal orientations, the MagArrow Magnetometer has operability worldwide without affecting survey orientation, making it much easier to use for the customer. Heading Errors Heading errors are a type of noise magnetometers can experience. They come from three sources: Sensor Console Operator Magnetic materials in the sensor itself are the primary cause of heading errors. The physics of Cesium and Potassium magnetometers can contribute small amounts to the total heading error. Magnetic contamination near the sensors, operating electronics, or operator can all contribute to heading error. Heading errors look like herringbone patterns in survey images. Alternate lines can also be corrugated. Dead-Zones vs Heading Errors while these two sources of error in magnetic data are different, there is overlap between them when operating a magnetometer like the MagArrow. Heading errors can be fixed relatively easily in software, where dead zones can be much harder to manage. If a line is completely ruined because of a dead zone then they will need to re-fly the line/mission which is time consuming. Even with advanced users, these sorts of mishaps can happen. Additionally, the closer a mag sensor operates to a dead-zone, the larger a heading error will be measured. With compensation software and a pre-survey heading error flight, heading error can be reduced dramatically to around 1 nT for the MagArrow. Click to view the difference between Raw and Processed MagArrow Data The MagArrow is only outputting a single value as a means to create a “no-dead-zone” system. Obviously each sensor has a dead zone themselves, but with the sensors orientated orthogonally at least one sensor at all times will have a magnetic measurement. By combining the measurements from both sensors it is possible to generate a constant magnetic field measurement independent of orientation and location in the world. If the data from each MFAM sensor in the MagArrow was individually reported there would be gaps in the mag fields observed by either sensor as you fly, rotate, and swing.

The OS software requirements are provided which each release of the software when filling out the ECR/ECO. Those requirements depend on the version released. Over the last 25 years these requirements have changed. The software only Supports Windows. We do not Support Linux. The last version of the SCS software Support all 32-bit and 64-bit of Windows since Windows 7. Windows servers are excluded, since they have not been tested, but should work. The hardware requirements are more complicated as it depends on the type of seismic survey, number of channels and software product SCS (SGOS, MGOS, ESOS, ...), SAS and options. It also depends how many network cards are needed, sample rate, and record length. For small systems, SCS will require at a minimum 512MB of free memory. For large systems up to a Maximum of 2GB of free memory. The CPU follow the same pattern. Any CPU since Pentium 90, if Supported by the OS, will work for small systems. A bigger survey system and continuous recording software may need i5 or i7 type CPU. An SSD drive may also be needed. See SCS software license agreement.

Geometrics seismographs are designed to trigger on a contact closure, contact open, or signal input. The trigger circuit has protect from high voltages, but it is possible to damage the input circuit if voltages outside the specified range are connected directly to the input circuit. It is recommended that input signals, or voltages do not exceed + 10 volts. A typical voltage measurement using a hand held volt meter on pins A (+) and B (-) of the 3 pin trigger input connector will be 4.9 volts DC. Voltages less than 4.0 volts may indicate a problem with the trigger circuitry. Often times the unit will continue to operate and trigger, but should be serviced at the next opportunity. If the circuit has been damaged, typical problems will include false triggers, or failure to trigger. To verify the trigger function of the Seismograph, begin by removing the external connector from the trigger input, and short pins "A" and "B" together on the trigger input connector of the seismograph. The unit should trigger each time the pins touched as long as the interval between triggers is greater than the record time or the trigger hold off whichever is longer. It should not trigger unless these pins are touched. If consistent triggering is achieved using this method, then attach the hammer switch directly to the seismograph. Do not put the hammer switch on a hammer yet. Tap the hammer switch cylinder on the edge of a table or other hard object and verify consistent triggering. Watch the stack count on the screen to confirm each tap of the hammer switch results in a trigger of seismograph. Check the trigger hold off setting and trigger sensitivity settings. Set the trigger hold off to 0.5 sec. and the trigger sensitivity to 50. If the seismograph is triggering correctly, insert any trigger extension cables between the hammer switch and the seismograph. Repeat the test to confirm consistent triggering. Then attach the hammer switch to the hammer, or other device used for triggering. Make sure the cylinder of the hammer switch is firmly taped to the handle, and the direction of motion is across the diameter of the cylinder. You can also attach a geophone or other signal producing devise at this point and verify proper triggering. If the unit does not properly trigger, contact Support with the results of the tests above for assistance.

hi, i have downloaded the .exe file. when i ran it, it showed 'trial expired' do you have new version available or new trial? thank you

Customer had problem connecting Wi-Fi using domain magarrow.net. Solution: Verify the blinking LED patterns are ok: 1) One steady blink and a pause, about once per second - The MagArrow is ready for a WIFI connection from your device. 2) Two short blinks followed by a pause – A device is connected to the MagArrow’s WIFI. If your device or another nearby device is set to connect automatically, this two-blink pattern might commence quite soon after power-on. If the MagArrow LED blinks normally, please try to connect to 192.168.1.1, instead of magarrow.net. If the LEDs don’t blink in these patterns, refer to the user manual’s troubleshooting section and/or contact Support@geometrics.com

I have attached the instructions that are sent with a new order acknowledgment. (Installation and Transfer) The license is assigned to a specific Registration ID once Fully purchased. This ID can be assigned to a person (we like to know for our own records) if possible but not required and can be transferred to other PC’s as needed. The ID works like a softkey dongle. The software can be active on only one machine at a time. I attached a simplified “Steps with windows_SI Transfer procedure that shows how the software can be moved. The PC must connected to the internet to affect the first part of the transfer (which removes the ID from the PC, making available for the next). Then to place the Reg ID on the next computer is just following the original registration process. Do not lose the ID. Make sure that the ID has been removed before a disc is reimaged or an employee leaves with the PC. If for some reason the Reg ID has to be reset, (computer dies before the ID can be removed) I will require a statement and an end user then for my records. I am available to discuss if needed at the number below 0700-1500 PST.

@kuldeep, No, the data streaming is ONLY through the Ethernet port, not the UART5 port. Current instrument software does not Support the UART5 streaming. An example C code to stream MFAM data through the Dev Kit using TCP protocol can be found at:

Summary New releases of the MagEx and G-864 magnetometers include automated updates of instrument software (the embedded sofware, sometimes called firmware) into the G-864 MagEx instruments. This feature eliminates an additional installation process and reduces the need for customers to track software versions and compatibilities. How does it work?When the MagNav app connects to an instrument, it determines whether the instrument's software should be updated. If an update is available, MagNav informs the user, who can choose to update the software or to wait until later. If the user agrees, MagNav sends the update to the instrument, which installs the software and restarts. After the user reconnects the WiFi and restarts MagNav, the customer enjoys the benefits of the new version. If the automated process is not available for any reason, the existing standard install process, using a USB, will still be available to install software on the instrument, One last time for G-864 customers...Existing G-864 customers will need to run the manual install one last time, because the instruments shipped before the introduction of this feature can't execute the automatic upgrade. After that final manual update, those G-864s will Support automatic udate. Does this also automatically install new versions of MagNav?No, this feature does not automatically install a new version of MagNav; MagNav will still be installed onto the tablet from a USB drive. This feature involves the elimination of the separate, additional installation of software into the instrument.

Geodes do have an option to have a factory installed oscillator board at extra cost that is used to test the electronics in the Geode. These are not normally installed for most of our users. Users do have the option to run geophone tests using the standard equipped Geode Seismograph that can run line continuity and geophone tests. This can be accessed from the system->tests->Run Geophone/Line tests. Oscillator boards are typically installed during purchase. Fewer than 5% of the customers purchase that option, that level of QC is typically not necessary. For more information please read the test box manual. We no longer supply the Test Box to external customers. A description of how to run the tests if you use the test box or if you use the internal oscillators is described in Section 2.11.3.1 RUN INSTRUMENT TESTS (OPTIONAL ADD-ON FEATURE) of the manual. The latest standard Geode Operations Manual has more information. You can run the tests outlined in the Geode Operations Manual to detect the bad geophones and spread cables. If you require a calibration certificate for your Geode please consult our Support Note. All Geophysical surveys require interpretation given limited understanding of the site, data from equipment, and ground truthing. Any interpretation provided is the best that can be provided according to the geophysical expertise and experience of the geophysicist.
