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

① Selects input signal connections on front or rear panel.

② Connect the test leads to the terminals as shown in Figure 3-4.

③ 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.

④ Press SHIFT+DCV or SHIFT+ACV buttons for DCI or ACI

measurement.

⑤ Select the auto-range function by pressing AUTO button on the front
