User Manual

WARNING
To avoid possible electric shock or personal injury, and to
avoid possible damage to the Meter or to the equipment being
tested, adhere to the following rules:
● When servicing the Meter, use only the same model number
or identical electrical specifications replacement parts.
● When using the test leads, keep your fingers behind the
finger guards.
● Do not apply more than the rated voltage, as marked on the
Meter, between the terminals or between any terminal and
grounding.
● Do not use or store the Meter in a high-temperature
environment, do not expose to high levels of humidity, or
near strong magnetic fields. The performance of the Meter
may deteriorate after dampening.
● When the Meter is working at an effective voltage over 60V
in DC or 30V rms in AC, special care should be taken
because there is a danger of electric shock.
● When measuring, connect the neutral wire or ground wire
first, and then connect the live wire; when disconnecting,
disconnect the live wire first, and then disconnect the neutral
wire and the ground wire.
● 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.
● Remove the connection between the testing leads and the
circuit being tested and turn the Meter power off before
opening the Meter case.
● The manual rotary switch should be placed in the correct
position before measurement and should NOT be moved
during measurement to prevent damage to the Meter.
● Turn the Meter off when not in use and take out the battery
when it is not going to be used for an extended period.
Regularly check the battery as it may leak when it has not
been used for some time. Replace the battery as soon as
leaking appears. A leaking battery will damage the Meter.

● The reading will be displayed on the LCD screen.
● Insert the red test lead into the “Input” jack
and the black test lead into the “COM” jack.
Ⅲ. MEASURING FREQUENCY/DUTY CYCLE
● Turn the rotary dial to the setting.
Hz%
● The reading will be displayed on the LCD screen.
Ⅳ. MEASURING RESISTANCE
● Turn the rotary dial to the setting.
Ω
● Insert the red test lead into the “Input” jack
and the black test lead into the “COM” jack.
● The results will appear on the LCD display.
● Place the test leads at both ends of the resistance to be
measured and maintain strong contact.
RESISTANCE NOTES:
● Do not change the resistance while taking a measurement.
Doing so may damage the Meter and affect the test results.
● Do not directly measure the internal resistance of micrometers,
galvanometers, batteries, and other instruments.
● Do not test parallel circuits. The accuracy of the
measurement will be affected, and the results may not be
accurate.
● If the measured value is equal to the nominal resistance of
the resistor or within the range of error, the resistor is
functioning correctly.
● If there is a large deviation between the nominal resistance
and the measured resistance, the resistor is bad.
● If the measured resistance is infinite (open circuit), zero
(short circuit), or unstable, it means the resistor is damaged
and can no longer be used.

MAINTENANCE
CLEANING THE METER:
If there is dust or humidity in the terminals, it may produce
erroneous measurements. Please clean the Meter as follows:
● Turn of the power to the Meter and remove the test leads.
● Wipe the case with a damp cloth or mild detergent. Do not
use abrasives or solvents. Wipe the contacts in each
terminal with a clean cotton swab dampened in alcohol.
REPLACING THE BATTERY AND FUSE
BATTERY REPLACEMENT:
● Turn off the Meter and remove the test leads.
● Remove the screws on the battery cover with a screwdriver,
and remove the cover.
● Remove the old battery and replace it with a new battery of
the same specification. Please pay attention to the polarity
of the battery. The positive and negative polarity of each
battery is marked in the battery box.
● Put the battery cover back to its original position and fix the
battery cover with the removed screws.
REPLACING FUSES:
Fuses rarely need to be replaced and are usually blown due
to operator error. To replace the fuses:
● Disconnect the test leads.
● Remove the rubber sleeve and screws on the back cover of
the Meter.
● Open the back of the Meter and replace with fuses of the
same rating.
It is crucial that the replacement fuses have the same
rating:
Fuse 1: F600mA/250V fuse,6mmX32mm
Fuse 2: F10A/250V fuse,6mmX32mm

personal protective equipment (such as approved rubber
gloves, masks, and flame-retardant clothing, etc.) to prevent
injury from electric shocks and arcs when hazardous live
conductors are exposed.
● Check whether the Meter is working normally by measuring
the known voltage, do not use if the readings are incorrect or
the Meter is damaged.
