4 Setup and Operation

4.1 Gauge start up and operation

Read this user manual in its entirety before operating the instrument.
The signal output is available when power is applied to the gauge. Allow for a stabilizing time of approx. 10 min.
Once the gauge has been switched on, it can remain in operation continuously regardless of the pressure.
Connect power to the PCM301 using the designated pins 3 and 4 of the 9-pin D-sub connector. Alternatively,
you can power the device by connecting InstruTech's PS401-A power supply to the gauge.
