3.2 Current Measurements (DC & AC)
The ranges for DC current measurements in ATM3500A are 10mA,
100mA, 1A and 3A. For AC current measurements, the range is 1A
with a sensitivity of 1
μ
A to 3A AC-Coupled TRMS with a sensitivity of
10
μ
A.
Figure 3-4
and
3-5
show you how to measure DC/AC currents
in ATM3500A.
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
