Configuration
To calibrate the Helium Level Sensor :
1. Insert the “full” Level calibration standard
2. Press “measure”
3. Wait minimum for the required time (ee above)
4. Press “get value” at the corresponding field. This shows the voltage acress the mea-
surement resistor. For full, this should be zero volts (except for ECL 00 Peripheral
Control Boards, in which case this value will be about 5).
5. Repeat using the “empty” calibration standard.
6. For empty, this should be around 6 volts (except for ECL 00 Peripheral Control
Boards, in which case this value will be about 28).
7. Press “Write to NVRAM”.
Helium Level Correction (ECL00 Peripheral Control Boards only
ECL00 Peripheral Control Boards require an offset correction of 7%. This is entered in
the section below the helium level calibration:
