The GP-Probe TGE2 is equipped with a built-in current sensor that measures the consumption of a connected active GNSS antenna. The normal current consumption is within 10mA. If the current is near zero, the device will display error code 475.


To measure the current consumption, the device's internal antenna power supply must be enabled. However, if using a passive antenna, the internal power supply must be disabled to avoid error code 476 - short circuit.


Reason: GNSS port is active and the GNSS antenna power supply is enabled, but the GNSS antenna is not connected.


Solution 1: If you do not intend to use this GNSS port, deactivate it in the configuration panel:


Solution 2: If you use a passive GNSS antenna, disable the power supply for this channel in the configuration panel
