(For systems purchased before 7/09- Modules will have black caps)
Q57. What is the Module's Battery Life?
The chart below shows the battery life expectancy with 3 different Live Intervals. Extended battery life can be gained by:
- always unplugging the battery pack when a Module is not being used
- by utilizing a longer Live Interval and Recording Interval during testing
| Live Interval |

Q58.How do I check the Gas Production Modules to ensure that they are operating correctly?
To see if the Modules are communicating pressure to the computer, if they are holding pressure (no leaks) and if the Vent Valve is working properly. See Service Procedure #115.
Q59. Can current data be retrieved from a run that has been interrupted do to power outages, computer glitches etc.?
The GPM program makes a backup file when the first recording in an analysis is made. It then overwrites this file the next time a recording is made, each time including all the data from the start of the run.
If the GPM program is closed, and restarted, the file again gets overwritten and all the data from the first analysis is lost.
Therefore, if you have lost a run due to a computer glitch, power outage, etc. do not start a new run until you have tried to retrieve data from the backup file. As soon as you start a new run, the backup file is overwritten.
Below is the file path for the back-up file. "QCLAPTOP" directory is the name of our computer. You will need to insert the name of your computer in this path. The Autosave File is named "GPM Autosave.xls." You may have to search your c: directory as different operating systems may structure the directory tree differently during installation.
c:\documents and settings\qclaptop\local settings\temp\GPM Autosave.xls
Q60. How do I convert psi increase to Gas Produced?
To convert psi to Gas Produced See Service Procedure #123
Q61. My Module does not seem to be holding pressure. What should I do?
To see if the Module is communicating pressure to the computer, if it is holding pressure (no leaks) and if the Vent Valve is working properly, See Service Procedure #115.
Q62. My Module doesn't seem to be releasing pressure at its set level. What should I do?
To see if the Module is communicating pressure to the computer, if it is holding pressure (no leaks) and if the Vent Valve is working properly, See Service Procedure #115.
