Zeroing the transducer
The WPS600 has a zeroing function to ensure its long-term accuracy. The
transducer should be zeroed before first use, and can be zeroed again if the unit
starts to show an error in the zero-pressure reading.
Begin with the transducer switched off.
If the transducer is connected to a pressurized system, make sure that the
system is switched off and the pressure has been safely released.
Disconnect any items that are connected to the transducer’s inlet port.
Switch the transducer on and check that one of the range LEDs is lit.
Press both the “60 BAR” and “600 BAR” buttons at the same time, then release
them. Both range LEDs will flash for a few seconds, and then the “600 BAR” LED
will remain continuously lit.
The transducer is now zeroed.
