Always place the CAL/MEAS switch in the MEAS position during normal
flowmeter measuring operations. Having the switch in the MEAS
position prevents anyone from inadvertently changing the actual stored
zero value and other critical calibration parameters.
Zero Test values can be useful for troubleshooting a flowmeter problem
or revealing a hidden condition that may have an adverse effect on
flowmeter performance. See Appendix A, Troubleshooting, for
information on Repeating Zero Test Measurement and Comparing Zero
Adjust and Zero Test Values.
Reversing Direction of Positive Flow Measurement
In certain installations it may be desirable to change the direction of
positive flow measurement opposite to the forward flow arrow on the
meter body nameplate.
To reverse the direction of positive flow measurement, exchange the
location of the white and red wires on the electrode signal cable at
terminal X2 on the converter. The white wire will now be in terminal 14
and the red wire will now be in terminal 16.
After changing the location of the white and red wires, it is necessary to
conduct a new hydraulic zero adjustment (zero adjust) before resuming
normal measuring operations.
