Making Measurements
% Scale of 4-20 mA or 0-20 mA
The 4-20 mA current loop output from a transmitter is a type of electrical signal
that is used in a series circuit to provide a robust measurement signal that is
proportional to the applied pressure, temperature, or flow in process control. The
signal is a current loop where 4 mA represents the zero percent signal and 20 mA
represents the 100 percent signal.
The % scale for 4-20 mA or 0-20 mA in this multimeter is calculated using its
corresponding DC mA measurement. The multimeter will automatically optimize
the best resolution for the selected measurement. Two ranges are available for the
% scale as shown in
To display the current measurement in % scale:
1 Position your multimeter's rotary switch position to

The analog bar graph displays the current measurement value. (In the example
above, 8 mA is represented as 25% in the 4-20 mA % scale.)
