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 10A 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 2000µA AC, set the function switch to the µA position
and insert the red test lead banana plug into the (A) jack.
3. 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.
4. For current measurements up to 10A AC, set the function switch to the A position and
insert the red test lead banana plug into the 10A jack.
5.
Press the AC/DC button until “AC” appears in the display.
6. Remove power from the circuit under test, then open up the circuit at the point where
you wish to measure current.
7. 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.
8. Apply power to the circuit.
9. Read the current in the display. The display will indicate the proper decimal point, value
and symbol.
CLAMP
–ON ADAPTOR AC/DC CURRENT MEASUREMENTS
1. Set the function switch to the A DC/AC (clamp
–on adaptor) position
2. Insert the clamp
–on adaptor black test lead banana plug into the negative (COM) jack
and the red test lead banana plug into the positive (V) jack.
3.
Press the MODE button until “AC/DC” appears in the display.
4. Press the trigger to open jaw. Fully enclose one conductor to be measured.
5. Read the AC/DC current in the display.
NOTE: The output analog signal Sensitivity of The AC/DC CLAMP
–ON ADAPTOR is
1mV/A
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
Ω
2. Insert the black test lead banana plug into the negative (COM) jack and the red test lead
banana plug into the positive Ω jack.
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 and symbol.
