or current than the set range of the 
multimeter will allow.

4)

Do not touch the metal

probes of the test leads when making a
measurement.

5) Replace worn test leads. Do not use test

leads with broken or tattered insulation. Only
test leads meeting ETL, cETL, CE CAT II
500V IA    can be used in this multimeter.

6) Discharge a capacitor before measuring it.

7) Remove the test leads from the circuit being

measured as soon as the test is completed.

8)

Do not measure voltage

when the function/range switch is set on
the resistance (ohms) or the current (mA)
settings. Never measure current when the
meter is set on the resistance range.
Never measure AC voltage when the
meter is set on DC voltage or DCmA.
Setting the meter on the incorrect function
may burn out some of the internal circuitry
and may pose a safety hazard.

3. Operating Suggestions

1) Set the function/range switch to the proper

position before making a measurement.
When the voltage or current is not known, it
MUST be determined that the capacity of
the selected range will handle the amount of
voltage or current in the circuit (see #3
under 

For Your Safety). Always start with the

highest range in the function. If the 
reading falls within the range of a lower 
setting, reset the function/range switch to

the appropriate setting for greater accuracy.

2) Avoid placing the meter in areas where 

vibration, dust or dirt are present. Do not
store the meter in excessively hot, humid
or damp places. This meter is a sensitive 
measuring device and should be treated
with the same regard as other electrical
and electronic devices.

3) Using the meter in areas with high magnetic

fields can result in inaccurate readings. For
greatest accuracy, lay the meter flat on a
non-metallic surface.

4) When the meter is not in use, keep the

function/range switch in the OFF position.
This keeps the needle indicator from
deflecting or ”bouncing” excessively.

5) When disconnecting the test leads from

the unit, always grasp the leads where the
input jacks meet the meter housing. Never
pull the leads out of the jacks by the 
insulated wire or transport the meter using
the test leads as a carrying strap.

6) Never immerse the meter in water or 

solvents. To clean the housing use a damp
cloth with a minimal amount of mild soap.

7) If the resistance (ohms) function of the

meter is not going to be used for a week or
more, remove the internal battery to avoid
potential leaks that may damage the unit.

3.1 Preliminary Adjustments

Fully seat the test leads in the correct input
jacks. If necessary, using a small flat tip 
screwdriver, slowly turn the mechanical zero
