COMMISSION: ON THE BENCH OR IN THE LOOP
Commission the Model PX2088 Analog transmitter before or after
installation. It may be useful to commission the transmitter on the bench before
installation to ensure proper operation and to avoid exposing the transmitter
electronics to the plant environment. Commissioning consists of applying pressure
and setting the zero and span to the desired values.

TEST TERMINALS
Terminals for connecting an ammeter to the transmitter are provided in both the
terminal and the electronics compartments. To connect an ammeter in the terminal
compartment, connect the positive lead to the terminal marked “+TEST,” and the
negative lead to the terminal marked “–”. To connect an ammeter in the electronics
compartment, attach the positive lead to the terminal marked “+ TEST,” and the
negative lead to the terminal marked “– TEST” (see Figure 3-2).
Do not contact meter leads from
either test terminal on the output board to case ground. This can result in the maximum
current from the power supply flowing through the test meter and may blow the test meter
fuse, or damage the test meter or transmitter.
