3.2 Current Measurements (DC & AC)

The ranges for DC current measurements in 1201 are 10mA, 100mA, 1A

and 3A. For AC current measurements, the range is 1A with a sensitivity

of 1 μA to 3A AC-Coupled TRMS with a sensitivity of 10μA. Figure

3-4 and 3-5 show you how to measure DC/AC currents in 1201.

Warning! The maximum input current allowed is 3A, 250V. Do not

apply excess current to your meter to avoid damaging the fuse of current

input.

※ Note: To eliminate the thermal EMFs due to the differences between

two metals, use copper leads to connect your source signal to the meter.

How to measure current

Selects input signal connections on front or rear panel.

Connect the test leads to the terminals as shown in Figure 3-4.

Set RESOLUTION of DCI (Refer to 4.1.3), BANDWIDTH of ACI (Refer

to 4.1.2.1) or skip this step if default is to be used.

Press SHIFT+DCV or SHIFT+ACV buttons for DCI or ACI

measurement.

Select the auto-range function by pressing AUTO button on the front
