4. Operation Procedures
1) Add water to the water cup: the liquid level shall be over the small diameter (i.e. the depth of the liquid level is 12.5mm)
2) Connect power: Power on
3) Connect 485 communication: if necessary
4) Connect the specimen
5) Connect the calibration air source: adjust the pressure to 1Bar, adjust the throttle valve to slowly and continuously discharge the bubbles.
6) Functions of the calibration gas:
A) To calibrate whether the counter is accurated.
B) To prefill the tested pipeline and valve with gas.
C) To verify whether there is leakage in the tested pipeline and valve.
7) After above process are completed, then start the counting:
A) To Set the time
B) Push to reset
C) Start timing and start counting
D) Time to the end of the counting
E) Keep displaying the current quantity
8) Operation completion
9) Operation for changing water and adding water of the cup
