The Gassonic Surveyor has two interface LEDs, which will flash red or green depending on the state of the unit. The LED on the front
of the unit indicates the current mode of the Gassonic Surveyor, and the LED next to the sensor head communicates with the test-
and calibration tool Gassonoc 1701. During service operations with the Gassonic 1701 the communication LED is not visible.

The unit can operate with a supply voltage of 9 to 28 Vdc. Power consumption patterns below are calculated with a 33%
safety factor, and with the minimum voltage of 9 Vdc.
If the calibration or gain test was faulty the Gassonic 1701 beeps three times and a No response message is displayed
on the screen.
• Check if there is dirt on the optical window between the 1701 and the Gassonic Surveyor.
• Check if there is dirt on the windscreen or on the microphone.
• Replace microphone if nessesary.
