Message Explanation

Check Background Calibration Error – The background-gas sensor needs calibrated. Refer to Section 5.2.

Check Leak Calibration Error – The leak-gas sensor needs calibrated. Refer to Section 5.2.

Check Background Offset Error – The background-gas sensor did not properly zero during startup. Refer

to Section 5.2.

Check Leak Offset Error – The leak-gas sensor did not properly zero during startup. Refer to

Section 5.2.

Check Zeroing Bypassed Error – The ESC key was pressed during start up, thus bypassing the normal

sensor-zeroing process. Refer to Section 5.2.

Check Leak Rate Difference Error–The calculated leak rate difference between measurements #1 and #2

during an automatic or manual leak test was greater than 100%. Refer to

Section 5.2.

Check Background Greater

Than Leak

Error–The measured background gas level was greater than the measured leak

gas concentration. Refer to Section 5.2.

Sample Time The amount of time that a leak rate measurement has been in progress.

Purging Sensors The instrument automatically turns on both sensor pumps to purge the

background-gas and leak-gas sensor chambers. This action occurred because

during an idle period (blower not running) or during shutdown the instrument

has detected that more than 50 ppm of natural gas is present in the sensor

chamber(s).

Low Battery Error–Battery voltage has fallen below 4.0 volts. Refer to Section 5.2.
