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 200mA DC, set the function
switch to the mA range and insert the red test lead banana plug
into the (mA) jack.
3. For current measurements up to 20A DC, set the function
switch to the A position and insert the red test lead banana plug
into the 20A jack.
4. Remove power from the circuit under test, then open up the
circuit at the point where you wish to measure current.
5. 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.
6. Apply power to the circuit.
7. Read the current in the display. The display will indicate the
proper decimal point, value.

AC CURRENT MEASUREMENTS

WARNING: To avoid electric shock, do not measure AC current
on any circuit whose voltage exceeds 250V AC.
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 200mA AC, set the function
switch to the mA range and insert the red test lead banana plug
into the (mA) jack.
3. For current measurements up to 20A AC, set the function switch to
the A position and insert the red test lead banana plug into the 20A
jack.
4. Remove power from the circuit under test, then open up the
circuit at the point where you wish to measure current.
5. Touch the black test probe tip to the negative side of the circuit.
And touch the red test probe tip to the positive side of the
circuit.
6. Apply power to the circuit.
7. Read the current in the display. The display will indicate
the proper decimal point, value.

RESISTANCE MEASUREMENTS

WARNING: To avoid electric shock, disconnect power to the unit
under test and discharge all capacitors before taking any
resistance measurements. Remove the batteries and unplug the
line cords.
1. Set the function switch to the
2. Insert the black test lead banana plug into the negative (COM)
jack and the red test lead banana plug into the positive
3. Touch the test probe tips across the circuit or part under test. It
Is best to disconnect one side of the part under test so the rest
of the circuit will not interfere with the resistance reading.
4. Read the resistance in the display. The display will indicate the
proper decimal point, value
