Read this operators manual thoroughly before using this meter.
This manual is intended to provide basic information regarding
this meter 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.
Use extreme caution when using this meter. Improper
! WARNING WARNING
use of this meter 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 meter if you are
unfamiliar with electrical circuits and proper test procedures.
SAFETY WARNINGS
This instrument has been designed, manufactured and tested according
to IEC61010: Safety requirements for Electronic Measuring apparatus, and
delivered in the best condition after passing inspection. This instruction
manual contains warnings and safety rules which must be observed by
the user to ensure safe operation of the instrument and retain it in safe
condition. Therefore, read through these operating instructions before using
the instrument.

over AC 600 V exists.
• Do not attempt to take measurements in the presence of flammable
gasses. Otherwise, the use of the instrument may cause sparking, which
can lead to an explosion.
• This tester is designed for intermittent duty only (On 15 seconds, Off 240
seconds). It should only take several seconds to note a voltage indication.
If the reading is maintained longer than 15 seconds, damage to the unit
may occur.

conditions, such as broken case or exposed metal parts are
found on the instrument.
• Do not install substitute parts or make any modification to the instrument.
For repair or re-calibration, return the instrument to your local distributor
from where it was purchased.
• Verify proper operation on a known source before use or taking action as
a result of the indication of the instrument.
Use appropriate personal protective equipment such as
insulating gloves, insulating boots, and safety glasses.
• Do not expose the instrument to the direct sun, high temperature and
humidity or dewfall.
• Using the meter in areas with high magnetic fields can result in inaccurate
readings.

32 °F – 104 °F (0 °C – 40 °C).
• This instrument isn't dust and water proofed. Keep away from dust
and water.
• Cleaning: Use a cloth dipped in water or neutral detergent for cleaning the
instrument. Do not use abrasives or solvents otherwise instrument may get
damaged, deformed or discolored.

4.0 OPERATION
This meter is designed with probe
holders to allow for maximum
versatility and single hand testing.
Refer to the drawings in Fig. 1 for
common setups.
When using the test leads, the
tester will automatically activate
when connected to AC or DC
voltage. The tester will automatically
select the proper function.
4.1 Measuring DC Voltage Levels
Measure the voltage by touching
the test lead tips to the circuit where
the value of voltage is needed. If
the yellow test lead is on the
positive contact the +VDC light will
illuminate. If the yellow test lead is
on the negative contact the -VDC Fig. 2
light will illuminate. Fig. 2
Read the voltage level from the DC
voltage scale.
4.2 Measuring AC Voltage Levels
Measure the voltage by touching
the test lead tips to the circuit where
the value of voltage is needed. Both
polarity indicators will illuminate to
indicate AC Voltage. Fig. 3
Read the level from the AC voltage
scale. The polarity of the leads does
not matter for AC voltage
measurements.
