Module Lock-Up
In the rare event that the BIOGAS 3000 ‘locks up’ and will not recognize button
presses, the system should automatically power cycle the module due to a loss
of communications.
If this does not occur or fix the problem, isolate the supply to the system and
leave the system switched off for 60 seconds. After this duration, turn the
power back on and check the systems operation.
If the problem persists, please contact our technical support team at (800) 968-
2026 or email

Under and Over Range Codes
If a reading is under range (i.e. below zero) it will display ‘less than’ chevrons
(<<<). This can occur if:
A channel has been incorrectly user calibrated
The BIOGAS 3000 module has been damaged (e.g. during transit)
The BIOGAS 3000 module has drifted out of calibration or it is due for
factory calibration.
If a reading is over range (i.e. above the maximum allowed value) it will display
‘more than’ chevrons (>>>). This can occur:
For the same reasons as an under range error
If the channel is reading more than its acceptable limit (e.g. CH
4
> 100%)
Due to potential cross gas effects.
In most circumstances, a return to factory settings (see
) and
performing a user calibration (see
) will resolve the
error. If the error is not cleared by performing these tasks, please contact our
technical support team at (800) 968-2026 or email
