G SAFETY INFORMATION
Understand and follow operating instructions carefully.
GWARNING
■Do not use test leads or the multimeter if they are damaged
■Do not use the multimeter if the tester is not operating properly
■To reduce risk of fire and shock do not expose this product to rain or
any moisture
■When using test leads or probes, keep fingers behind the finger guards.
■Remove test leads from meter before opening the battery door or meter
case.
■Use the meter only as specified in this manual or the protection by the
meter might be impaired.
■Always use proper terminals, switch position, and range for measurements.
■Never attempt a voltage measurement with the test lead inserted into the
A input terminal.
■Verify the meter’s operation by measuring a known voltage. If in doubt,
have the meter serviced.
■Do not apply more than the rated voltage, as marked on meter, between
terminals or between any terminal and earth ground.
■Do not attempt a current measurement when the open voltage is above the
fuse protection rating.
■Suspected open circuit voltage can be checked with voltage function.
■Only replace the blown fuse with the proper rating as specified in this
manual.
■Use caution with voltages above 30 Vac rms, 42 Vac peak , or 60 Vdc.
These voltages pose a shock hazard.
■To avoid false readings that can lead to electric shock and injury, replace
battery as soon as low battery indicator appears.
■Disconnect circuit power and discharge all high voltage capacitors before
testing resistance, continuity, diodes, or capacitance.
■Do not use meter around explosive gas or vapour.

GCAUTION
■Disconnect the test leads from the test points before changing the position
of the function rotary switch.
■Never connect a source of voltage with the function rotary switch
W, , d,a,A, bposition.
■Do not expose Meter to extremes in temperature or high humidity.
■Never set the meter in daA function to measure the voltage of a
power supply circuit in equipment that could result in damage the meter
and the equipment under test.

Non-Contact Voltage Alert (VOLTSENSE)
1. Volt sense switch will be activated on any function or at OFF status.
2. Test leads are not used for the Volt sense test.
3. Press the Volt sense button. The display will blank out, a tone sounds
and the red LED lights up to verify the instrument is operational. The
Volt sense button must be held down to detect the presence of voltage
without use of the leads.
4. If a voltage of 50V to 600V (50 to 500Hz) is detected near the top of
meter a continuous tone sounds and the red LED near the top of meter
illuminates.
