6.4. AC CURRENT (FREQUENCY, DUTY CYCLE) MEASUREMENT
CAUTION: Do not make 10A current measurements for longer than 30
seconds. Exceeding 30 seconds may cause damage to the
meter and/or the test leads.
1. Insert the black test lead banana plug into the negative COM input
jack.
2. For current measurements up to 6000 µA AC, set the function
switch to the µA AC/DC position and insert the red test lead banana
plug into the µA/mA input jack.
3. For current measurements up to 600mA AC, set the function switch
to the mA AC/DC position and insert the red test lead banana plug
into the µA/mA input jack.
4.
For current measurements up to 10A AC, set the function switch to
the 10A AC/DC position and insert the red test lead banana plug
into the 10A input jack.
5. Press the MODE Button to indicate "AC" on the display.
