Instrumentation and Control Device Measurements
For instrumentation control signal measurements, select [1-5 V] . This range corre-
sponds to the 4-20 mA output standard for instrumentation control. This setting automat-
ically sets 1- and 5-volt lower and upper limits, respectively, in the 10 V range.
Measurement accuracy is ±10 mV ±5 mV. To measure 4-20 mA current, connect a 250

shunt resistor b and – analog input terminals (p. 32).
Use the scaling function to scale measurements to any arbitrary unit value for display (p.
58).
