Reading Low and O
2
Reading High
If you believe that the CH
4
reading is lower than you expect or the O
2
reading is
higher than you expect, there could be two reasons for this:

There could be a leak in the tubing and when sampling you could be
drawing in air and diluting the sample. Refer to the
Pressure Test
section of this operating manual for instructions on how to pressure
test the BIOGAS 3000 system.

The BIOGAS 3000 has drifted since its calibration and may be due a user
calibration; see section
Gas Check and Calibration of this operating
manual for further information.
If after performing the above steps the problem is still present, please contact

9.12 Event Log
The BIOGAS 3000 incorporates the ability to log significant events performed
on the system via the event log. This can be used as an aid to monitoring the
use of the system and used as a diagnostic tool if there is a problem.
The system stores ten logs, each able to store 10kb of event memory. 10kb is
approximately 80-100 single event entries. Applicable events are stored in the
event log automatically and no user intervention is required. When the tenth
log file is full, the events of log file one are deleted and replaced with log file
eleven.
Below are some examples of events recorded to the logs:
