SAFETY PRECAUTIONS
Read this information before using the meter, taking special care regarding
any WARNING or IMPORTANT notices. The following safe practices and proper
operating procedures should be followed when using any multimeter:
•
Inspect the test leads for insulation damage or exposed metal.
Damaged leads should be replaced.
•
Select the proper function and range tor your measurement.
•
Avoid severe shocks and do not drop the multimeter.
•
Do not allow the meter to be used if it is damaged or if its safety is impaired
•
WARNING: To AVOID ELECTRIC SHOCK, USE CAUTION WHEN WORKING
ABOVE 40V DC OR 25V AC RMS. SUCH VOLTAGES POSE A SHOCK HAZARD.
•
Electrically disconnect the live, or hot test lead before disconnecting
the common test lead.
•
Follow all equipment safety procedures. Disconnect the input power
and discharge all high-voltage capacitors through a protective
impedance before testing in
Ω
and with the multimeter.
•
Avoid working alone.
•
When making a current measurement, turn the power off before
connecting the multimeter in the circuit. Overloading a current shunt
will cause excessive heat.
•
When measuring transformer secondary or motor winding current, check
the multimeter fuses first.
•
When testing circuits take extra care not to touch any bare metal
including the ends of the test probes.
•
The use of makeshift fuses and the short-circuiting of fuse holders is prohibited.
•
Whenever it is likely that the protection has been impaired, the meter shall
be made inoperative and be secured against any unintended operation.
•
Never attempt to measure a voltage or current higher than the maximum
rating of the meter.
•
Never perform resistance measurements on a live circuit.

DC Current Measurement
WARNING, Do not attempt to measure a current in excess of 10 Amps
1. Connect the BLACK test lead to the COM jack and the RED test lead to
the mA jack for a maximum of 2A. For inputs greater than 10A, move
the red test lead to the 10A jack.
2. Set the FUNCTION switch to the A --- range to be used and connect the
test leads in series with the load under measurement. Reverse polarity is
indicated by a “—” sign being displayed in front of the reading.
Note:
1. If the current range is not known beforehand, set the FUNCTION switch
to a high range and work down.
2. When only the figure “1” is displayed over range is being indicated and the
FUNCTION switch must be set to a higher range.
3. The maximum input current is 2A, or 10A depending on the jack used.
Excessive current will blow the fuse which must be replaced. The 10A
range is not protected by a fuse. The fuse rating should be 2A and
no more to prevent damage to the internal circuitry. The maximum
terminal voltage drop is 200mV.
AC Current measurement
WARNING, Do not attempt to measure a current in excess of 10 Amps
1. Connect the BLACK test lead to the COM jack and the RED test lead to
the mA jack for a maximum of 2A. For a maximum of 10A, move the
RED test lead to the 10A jack.
2. Set the FUNCTION switch to the A~ range to be used and connect the
test lead in series with the load to be measured.
Note: See DC Current Note 1 - 3
Resistance Measurement
IMPORTANT. When checking in-circuit resistance, ensure the circuit under test
has all power removed and that all capacitors are fully discharged.
1. Connect the BLACK test lead to the COM jack and the RED test lead to
the V/
Ω
jack. Note
: the polarity of the RED test lead is “+”.
2. Set the FUNCTION switch to the range to be used and connect the test
leads across the resistance to be measured.
