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
When the voltage or current is not known, it
MUST be determined that the capacity of
the selected range will handle the amount of

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.

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
jacks. If necessary, using a small flat tip
