7.9.2 Checking Calibration Contact Output

The calibration contacts are used for the solenoid valve drive signals for the Automatic Calibration

Unit. This output signal enables you to check the equipment operation. Check the flowmeter gas flow

for that operation.
Follow the steps in Table 7.9. The table uses an example with a zero gas solenoid valve.
