CAUTION: Do not make current measurements on the 20A
scale 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
jack.
2. For current measurements up
to 4000µA AC, set the
function switch to the yellow
µA position and insert the red
test lead banana plug into the
µA/mA jack
3. For current measurements up
to 400mA AC, set the function
switch to the yellow mA
position and insert the red test
lead banana plug into the
µA/mA jack.
4. For current measurements up
to 20A AC, set the function
switch to the yellow 20A
range and insert the red test
lead banana plug into the 20A
jack.
5. Press the SELECT button to
indicate “AC” on the display.
6. Remove power from the circuit under test, then open up the
