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:
•
WARNING: TO AVOID ELECTRIC SHOCK, USE CAUTION WHEN
WORKING ABOVE 40V DC OR 25V AC RMS. SUCH VOLTAGES POSE
A SHOCK HAZARD
•
Inspect the test leads for insulation damage or exposed metal.
Damaged leads should be replaced.
•
Select the proper function and range for 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.
•
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.
