Function 00
A hydraulic zero adjustment (Zero Adjust) or a Zero Test can be
conducted without access to the Zero Adjust pushbutton S4 on the
Junction Board.
To conduct a Function 00 Zero Test:
1. Make sure the flow tube is full of product and there is no flow or leakage.
2. Check all connection cables to make sure the terminations are tight and
dry. The position of the CAL/MEAS switch on the Main Board determines
whether a Zero Test or a Zero Adjust will be performed:

Before executing a Function 00 procedure, check
the position of the CAL/MEAS switch to avoid
performing an undesired Zero Adjust.
3. Press key F. Then press key 0. Then press key 0.
The display confirms the Zero-Adjust or Zero-Test according to the
position of the CAL/MEAS switch. The cursor counts down right to
left for 40 seconds showing the progress of the automatic zero
measurement. At the end of the 40 second automatic zero
measurement period, the visual display shows the zero value just
measured. This display remains until any key is pressed. The
display pauses four seconds and then reverts to the Measuring
Register.
