Flow System:
Pressure Sensor Calibration:
The flow system is monitored internally using one pressure sensor per point. Each pressure sensor has a
voltage offset which represents atmospheric pressure when the pumps are turned off. The
recommended range for the voltage offset per point is 1000-1400. The voltage offsets can be found by
following these steps:
1. Enter Setup Menu
2. Enter Factory Menu
3. Enter password 1225
4. Select the System tab
5. Press the Offsets button for any active analyzer (see image below)
If there is an offset voltage outside of the suggested range remove the sample line and press Set Offsets.
If the offset is still outside the suggested range refer to the CL96 Flow Troubleshooting Section.
