WARNING!
Use extreme caution when using
this multimeter. Improper use of this tester can
result in severe damage to property, severe
personal injury or death. Follow all instructions and
suggestions in this operators manual as well as
observing normal electrical safety precautions. Do not
use this multimeter if you are unfamiliar with electrical
circuits and proper test procedures.
2.1 For Your Safety
1)
WARNING! Use extreme caution when checking
electrical circuits.
2)
WARNING! Do not stand in wet or damp work
areas when working with electricity. Wear
rubber soled boots or shoes.
3)
WARNING! Do not apply more voltage 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.
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)
WARNING! 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 tester is set on the resistance range.
Never measure AC voltage when the tester is set on
DC voltage or DCmA/A. Setting the tester on the
incorrect function may burn out some of the internal
circuitry and may pose a safety hazard.

19 Measuring ranges
Zero Ohms Adjustment Dial: Located on the front left side of the housing.
Adjustment dial is used to zero the needle
indicator on the ohms scale while shorting the test
leads together.
Mechanical Zero
Located directly below the center of the scale,
Adjustment Screw:
used to align needle on the zero settings for
accurate readings.
Mirrored Scale Plate:
The mirror on the scale plate is used to line up the
needle with its reflection to improve the reading
accuracy by preventing parallax error.
Recessed Input Jacks:
Negative (-) input jack for black test lead, positive
(+) input jack for red test lead. Separate jack for
10 Amp range.
Important:
Read this operators manual thoroughly before using this
multimeter. This manual is intended to provide basic
information regarding this multimeter and to describe
common test procedures which can be made with this unit.
Many types of appliance, machinery and other electrical
circuit measurements are not addressed in this manual and
should be handled by experienced service technicians.
