Percentage scale of DC mA measurement
The percentage scale for 4 mA to 20 mA or 0 mA to 20 mA
is calculated based on the measured DC mA value.
1 Select the required range (4 mA to 20 mA or 0 mA to
20 mA) in the Setup mode (refer to Chapter 4, “Setting
the percentage scale readout”).
2 Turn the rotary switch to .
3 Press to select percentage scale display for DC mA
measurement.
4 Connect the red and black test leads to the positive and
negative input terminals respectively.
5 Probe the test points in series with the circuit and read
the display. The inset display in Figure 3- 3 shows the
percentage scale reading representing 20 mA in the range
of 4 mA to 20 mA.
