9.2 Converter Check / Calibration
9.2.1 0% Flow Rate Calibration (Zero Calibration)
Using Mag-Prover internal calibration circuit, 0% flow rate (hereafter called zero point) calibration
can be performed.
Checking the zero point

P1:FLOW CAL 0
0.0 % About 3 to 6 seconds later (Note 2), the zero calibration ends
and a new zero point appears.
P1:FLOW CAL 0%
Returns to the menu of calibration item selection.
Note 1: To cancel the adjustment from the condition of ADJUST READY, press CANCEL . The display returns
to the condition where zero point using the simulation input is displayed.
