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
Ω
shunt resistor b and – analog input terminals (p. 36).
Use the scaling function to scale measurements to any arbitrary unit value for display (p.
69).
If the Allowable Measurement Range of each Range is Significantly
Exceeded
“OVER” or “-OVER” is displayed for the numerical value or cursor value and the calcu-
lated value or saved data is handled as a full scale value.
Refer to “LR8432-20 Measurement Values” (p. A13).
