This starts the re-zeroing
process of the Sentinel 2, which
repeatedly reads the numeric
output from the transducer.
…Wait for this to stabilise
(e.g. wait for 10 readings)
and then click the “Save” button.
The value is stored.
Note: If the value does not stabilise and is showing readings with a difference of
more than 5, contact a HWM representative for advice.
Repeat the process for the second pressure transducer. This is identical but requires
selection of the “PRV Outlet pressure” transducer by picking “Channel 2” on the drop
-
down control.
To verify the transducers are re-zeroed, whilst still in
atmospheric conditions:
Select the P
RV Installation tab and click on the “Live
values” button.
The Upstream and Downstream pressure values
should now read zero, or very close to zero.
… Click the “Stop” button to end the verification.
