5.5.4 Selecting Magnetometer Channels
Normally when a GSM-19G gradiometer is used in a single channel mode (i.e. for magnetic
readings only), the lower sensor is used to take the readings but it is also possible to use the upper
channel for this purpose.
To change the channel, access the
Main Menu and press C-info. The following screen is displayed.
