When measuring instrumentation devices
• When measuring a 4-20 mA current, connect a 250
Ω
resistor between the positive and negative
input terminals.
See “Connecting voltage cables and thermocouples” in the Quick Start Manual.
• The [1-5 V] range is convenient when measuring output from 4-20 mA instrumentation devices.
• The [1-5 V] range is a range in which the lower and upper limits of the [10 V] range’s display
range are automatically set to 1 V and 5 V, respectively. If you wish to change the upper and
lower limit values, use the [10 V] range.
• The Strain Unit does not support 4-20 mA current measurement.
You can use the scaling function to convert measured voltage values to the desired values.
See “1.7 Using the Scaling Function” (p. 58).
