AC/DC Current Measurement
The GDM-8351 series DMMs have two input terminals for current
measurement. A 1A terminal for current less than 1A and a 10A
terminal for measurements up to 10A.
The units can measure 0 ~ 10A for both AC and DC current.
Set to ACI/DCI

Connect the test lead between the 10A terminal
and the COM terminal or DC/AC 1A terminal
and the COM terminal, depending on the input
current.
For current ≤ 1A use the 1A terminal; For
current up to 10A use the 10A terminal. The
display updates the reading.
