DC Current Measurements
CAUTION: Do not make current measurements on the 10A scale for
longer than 15 seconds followed by a 15 minute cool down period.
Exceeding 15 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 200mA DC position and insert the red test lead banana plug into
the V/Ω/mA jack.
3. For current measurements up to 10A DC, set the function switch to the
10A DC range and insert the red test lead banana plug into the 10A
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.
Resistance Measurements
1. Insert the black test lead banana plug into the negative COM jack and
the red test lead banana plug into the positive V/Ω/mA jack.
2. Set the function switch to the highest Ω position.
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 and then set the function switch to
the lowest Ω position that is greater than the actual or any anticipated
resistance.
