Use the Meter only as specified in this operating manual, otherwise the
protection provided by the Meter may be impaired.
In this manual, a Warning identifies conditions and actions that pose
hazards to the user, or may damage the Meter or the equipment under test.
A Note identifies the information that user should pay attention to
International electrical symbols used on the Meter and in this Operating
Manual are explained on page 6.
Rules For Safe Operation
Warning
To avoid possible electric shock or personal injury, and to avoid
possible damage to the Meter or to the equipment under test, adhere
to the following rules:
Before using the Meter inspect the case. Do not use the Meter if it
is damaged or the case (or part of the case) is removed. Look for
cracks or missing plastic. Pay attention to the insulation around the
connectors.
Inspect the test leads for damaged insulation or exposed metal.
Replace damaged test leads with identical model number or electrical
specifications before using the Meter.
Do not apply more that the rated voltage, as marked on the Meter.
When measurement has been completed, disconnect the
connection between the test leads and the circuit under test, remove
the testing leads away from the input terminals of the Meter and turn
Page 3
3
the Meter power off.
Do not carry out the measurement when the Meter’s back case and
/ or battery door is opened to avoid electric shock.
When the Meter working at an effective voltage over 30V in AC,
special care should be taken.
Use the proper terminals and function for your Measurements.
Do not use or store the Meter in an environment of high
temperature, humidity, explosive, inflammable and strong magnetic
field. The performance of the Meter may deteriorate after dampened.
Do not use the Meter if the surface of it is wet or the user’s hands
are wet.
When using the test leads, keep your fingers behind the finger
guards.
Replace the battery as soon as the battery Indicator appears.
With a low battery, the Meter might produce false readings that can
lead to electric shock and personal injury.
When opening the battery door, must make sure the Meter is
power off.
When servicing the Meter, use only the same model number or
identical electrical specifications replacement parts.
The internal circuit of the Meter shall not be altered at will to avoid
damage of the Meter and any accident.
Soft cloth and mild detergent should be used to clean the surface
of the Meter when servicing.
No abrasive and solvent should be used to prevent the surface of the
Meter from corrosion, damage and accident.
The Meter is suitable for indoor use.
Turn the Meter off when it is not in use and take out the battery
when not using for a long time.
Constantly check the battery as it may leak when it has been using
for some time, replace the battery as soon as leaking appears.
A leaking battery will damage the Meter.

True RMS Measurement and Average Value Measurement
The True RMS measurement method can measure accurately the effective
value of non-sine wave input signal.
Average value measurement method can measure the mean value of one
sine wave input signal, and then displays it as RMS value
When the input waveform has distortion, measuring tolerance will be
included. The total tolerance depends on the total distortion. Below table 1
shows the waveform coefficient and the relationship and the requested
changing factor of sine wave, square wave, pulse rectangle wave, sawtooth
triangle wave, RMS value and average value.

MAINTENANCE
This section provides basic maintenance information including battery
replacement instruction.
Warning
Do not attempt to repair or service your Meter unless you are qualified
to do so and have the relevant calibration, performance test, and
service information.
To avoid electrical shock or damage to the Met do not get water inside
the case.
A. General Service
● Periodically wipe the case with a damp cloth and mild detergent. Do not
use abrasives or solvents.
● To clean the terminals with cotton bar with detergent, as dirt or moisture
Page 36
36
in the terminals can affect readings.
● Turn the Meter power off when it is not in use.
● Take out the battery when it is not using for a long time.
● Do not use or store the Meter in a place of humidity, high temperature,
explosive, inflammable and strong magnetic field.
B. Replacing the Battery
Warning
To avoid false readings, which could lead to possible electric shock or
personal injury, replace the battery as soon as the battery indicator “ ”
appears.
Make sure the transformer jaw and the tests leads are disconected
from the circuit being tested before opening the case bottom.
To replace the battery:.
1. Press POWER to turn the Meter off and remove all the connections from
the input terminals
2. Turn the Meter’s front case down.
3. Remove the screw from the battery door, and separate the battery door
from the case bottom.
4. Rejoin the case bottom and the battery compartment ,and reinstall the
screw.
