Î Disconnect the supply voltage and pro-
tect it against unintentional reconnection.
Î Remove any lines to upstream compo-
nents (pneumatic input signal) and any
wires to downstream control equipment
(electric output signal).
Î Connect the pneumatic input to a pres-
sure instrument and the electric output to
a measuring instrument with sufficient
accuracy.
Î Switch on supply voltage.
Î Tune zero:
Î Set the input signal to 0.2 bar.
The output signal of the measuring
instrument must now indicate
0/4 mA or 0/2 V.
Î Correct deviations at the ZERO
potentiometer.
Î Tune span:
Î Raise the input signal from 0.2 bar to
1 bar.
The output signal of the measuring
instrument must now indicate 20 mA
or 10 V.
Î Correct deviations at the SPAN po-
tentiometer.
