Diagnostic Terminal mode. Record initial tare offset values at ‘0 min (a)’.
If the tare value is outside of +/- 10.0 L/min, replace the flowmeter.
If the tare value is outside of +/- (3.0 – 10.0 L/min) , send the following commands to tare the
flowmeter (items within <> indicate the key to press):
<
ENTER> <ENTER> *@=A <ENTER> A$$V <ENTER>
The tare offset should be reduced following the command. Repeat once more if it does not.
Record the post-tare offset into 0(b).
If the tare value is /- 3.0 L/min, record the offset into 0 (a), record n/a into 0(b).
Record the tare offset in the following time intervals.
