Dc Current Measurements - Craftsman 82337 Owner's Manual

DC CURRENT MEASUREMENTS

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 200 A DC, set the function
switch to the 200 A DC
position and insert the red test
lead banana plug into the
(uA/mA) jack.
3. For current measurements up
to 200mA DC, set the function
switch to the 200mA DC
position and insert the red test
lead banana plug into the
uA/(mA) jack.
4. For current measurements up
to 20A DC, set the function
switch to the 20ADC range
and insert the red test lead
banana plug into the (20A)
jack.
5. Remove power from the circuit under test, then open up the
circuit at the point where you wish to measure current.
6. Touch the black test probe tip to the negative side of the circuit.
Touch the red test probe tip to the positive side of the circuit.
7. Apply power to the circuit.
8. Read the current in the display.
