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.

Resistance and Capacitance

Note – To improve the measurement accuracy of small value capacitor, record the

reading with the test leads open, then subtract the residual capacitance of the meter

and leads from measurement.

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.

Fuse Replacement

Refer to the following diagram to replace fuse.

GUse only a fuse with the amperage, interrupt, voltage,

and speed rating speciﬁed.

˙ Fuse rating: 10A, 500V
