Question What does different Sensor Modes represent?

There are 3 different Sensor Modes: Heating, Locking and Normal.

Heating and Locking are stages during startup. Heating means the Cs cell is warming up and Locking indicates the laser locking (frequency/wavelength stabilizing) stage.

In room temperature, Heating should take less than 5 minutes and Locking less than 10 minutes.

If the startup time takes much longer than expected, please check the error code displayed on http://192.168.1.1/status.cgi (and click “Detailed Instrument Status”).
