"OVER" or "-OVER" is displayed in place of numerical/cursor values, and the following values
are applied to calculations and data storage.

Instrumentation and Control Device Measurements
• To measure 4-20 mA current, connect a 250
Ω
shunt resistor b and - analog input
terminals (p. 36).
• Select the [1-5V] range to measure 4-20 mA instrumentation control signal outputs.
• The [1-5V] setting automatically selects the [10V] range with an 5-V upper limit and 1-V
lower limit. To change the upper and lower limits, select the [10V] range.
Use the scaling function to scale measurements to any arbitrary unit
value for display (p. 71).
