| SGOS Calibration | 2 Relevance | 3 years ago | Gretchen Schmauder | Software | |
| Standard Procedure on Registering SCS Software Here's our standard procedure on registering the SCS (Seismic Controller Software): The latest version of the SCS is 11.1.69, which is used for Windows Operating Systems up to and including W-10 64 bit computers. Within the zip file you will find instructions as well as the installation file. Note: Installing the WinPcap is mandatory! After installing, you will need to register. In Order for us to issue the correct SCS registration we will need additional information. The preferred method is: 1. From the “Registration Window” select “Send Email or Save File to Disk”. 2. Fill out the report, to include serial number of seismograph. (type 0000 in sales No. field if not known) 3. Save the file to your computer. 4. Send an email with the file attached or embedded to: rrivera@geometrics.com and/or support@geometrics.com. We will then remit with a 40 character alphanumeric string that you can paste into the same “Registration Window.” Please understand that the SCS can be installed onto as many computers as you wish, yet each installation will generate its own unique user code and therefore need to be registered. | |||||

| Battery percentage and status | 2 Relevance | 3 years ago | Magnetics SW | MagEX | |
| Overview The MagEx instrument and the MagNav app both display information about the state of the instrument's battery. Battery state and reporting exist in bands according to percentage of remaining battery capacity: 30% or higher:The instrument has good remaining capacity.The LED on the instrument's power switch glows a solid green.MagNav displays the battery percentage or voltage in black text on a white background. Between 20% and 30%:The instrument has capacity to survey for additional time, but if you will be surveying a significant amount more, start thinking about changing the battery.The LED on the power switch is blue.MagNav displays the battery percentage with a blue background. Between 5% and 20%:You can continue to survey, but the battery is running low and you should consider changing the battery soon.The LED on the power switch is red.MagNav displays the battery percentage with a red background, and periodically notifies you that the battery is running low. Below 5%:The battery is running low, and the instrument may turn off at any time in Order to preserve battery health. You should change the battery as soon as possible. Temperature-related effects:Battery performance also changes as the temperature of the battery changes; as the temperature of a battery falls, the voltage it supplies also decreases, and the total energysupplied by the battery decreases. This means that in cold weather a battery will not last as long as in hot weather. The battery percentages reported in the instrument are adjusted for the effect of temperature; at a given battery voltage a cold battery will display a higher percentage than a warm battery will report. The effects of colder temperatures are not normally permanent; as a battery warms up, its output voltage and energy return to higher levels. Notes about the calculation:The MagEx instrument includes 2 batteries, and each battery includes 3 separate cells. Battery percentages are calculated from only one battery in the instrument - either the single battery if only one is connected, or from the better battery if two batteries are connected. Reported battery percentage is an estimate, based on measurements of the behavior of healthy batteries in instruments in the field and in the lab. Battery performance may change as a battery ages and as the temperature changes. The best practice for batteries is to use 2 healthy, fully charged batteries, and replace them both when the percentage falls below 20%. | |||||
| Can a Magnetometer Detect Gold | 2 Relevance | 3 years ago | Gretchen Schmauder | General Magnetometer Info | |
| There are basically three types of "gold": low concentration disseminated gold in ore, placer gold deposits and solid gold such as that associated with treasure. Magnetometers are used to find disseminated gold by its association with mineralized zones which also contain magnetite or other magnetic minerals. Magnetometers are often used in conjunction with airborne electromagnetic surveys to find the conductive ore bodies. Placer gold is the type found in buried stream channels such as the gold which sparked the California gold-rush in 1849. Gold dust and magnetic minerals have been concentrated in river banks over thousands of years. Where there is gold there is often magnetite and therefore the magnetometer can be used to locate placer gold deposits. Gold treasure is a different story and being non-magnetic gold, silver, and other precious minerals are not directly detectable by the magnetometer. The magnetometer can only detect ferrous (iron or steel) objects. If the gold is stored in an iron box or has iron materials next to the gold (such as colonial ship ballast stones in the marine environment), there is the possibility of detecting the iron material. This is true for land and marine (sunken galleon) gold bullion. The vast majority of target search surveys are performed on a grid in a "lawn mower" back and forth manner to cover the area of interest. Lane spacing is dependent on target size (magnetic mass). At a sensor to target distance of 2 to 3 meters there will need to be at least 1-2 kilograms of iron. This can produce a 1-2 nT anomaly that is detectable in a magnetically clean environment. The ideal environment would be in a plowed farm field or the bottom of the ocean away from human activity i.e., away from a port or harbor. You will probably not be able to detect this small of an anomaly in a city or port location. The more iron mass there is, the better the chance of detecting it. Training to use the magnetometer can take 1-2 days depending on experience with setting up computerized survey equipment and a GPS. Processing the magnetic data requires several days of training and would require a geophysical background to interpret the final maps. We provide free software to make maps and estimate the target depth of burial (inversion). If you are unfamiliar with this procedure, we would recommend that you find a local geotechnical firm to look at the data to determine if there are anomalies that should be investigated further. Remembering that non-ferrous materials do not cause anomalies (gold, silver, copper, brass, aluminum, gems) you will be looking for anomalies either associated with the container OR associated with ground disturbance (i.e., gravesite). In this way some anomalies can be detected where there has been an excavation such as a gravesite. In Order to understand the process more fully, we strongly suggest that you download and read the Applications Manual for Portable Magnetometers. Other additional resources are available. Understanding how the magnetometer functions and how the earth’s field responds to distortions due to ferrous materials will help you make good decisions about how to interpret and use the data to direct recovery or exploration efforts. | |||||
| Is the Self-Trigger Option Suitable for Refraction Surveys? | 2 Relevance | 3 years ago | Gretchen Schmauder | General Seismograph Info | |
| Can the Self Trigger function (extra purchased option) replace the conventional trigger (hammer switch) and trigger extension cables typically used in refraction work? Self-Triggering doesn’t provide sufficient timing accuracy to work for refraction surveys. For refraction interpretation, the accuracy of the absolute travel time between source event and arrival at the geophone must be on the Order of ≤ 5 milliseconds. This cannot be achieved with the self-triggering processes. This is because the self-triggering option works by breaking the data into small'Time Windows' and comparing the energy levels in these against the average background energy. These time windows and the ratio values are chosen by the user, so accuracy will depend upon the length of the window and how tightly you can specify the change in energy levels. In cases where you don't have a trigger switch, you can set up the Geode to provide pre-trigger data and place a geophone close to the source. The extra geophone acts as a trigger and will start the survey at T = 0. For more information, click here | |||||
