1. Zero adjustment
X14.1 – X14.2: open
Apply E = +4 mA ± 0.05 %, set the output value to A = 0 mA ± 0.1 % with
trimming potentiometer R41.
Set output value
X14.1 – X14.2 : open
Apply E = +12 mA ± 0.05 %, set the output value to A = +20 mA ± 0.1 % with
trimming potentiometer R42.
2. Zero adjustment
X14.1 – X14.2 : closed
Apply E = +12 mA ± 0.05 %, set the output value to A = 0 mA ± 0.1 % with
trimming potentiometer R41.
Check output value
X14.1 – X14.2 : closed
Apply E = +20 mA ± 0.05 %,
check output value A = +20 mA ± 0.1 %.
Apply E = +4 mA ± 0.05 %,
check output value A = -20 mA ± 0.1 %.
Check the intermediate values.
