CAUTION:
Do not make 20A 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
jack.
2. For current measurements up to 4000μA DC,
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 DC,
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 10A DC, set
the function switch to the yellow
10A/HZ
/%
position and insert the red test lead banana
plug into the
10A
jack.
5. Press the
