Safety notices:
The use of meter instruments near devices with large electromagne
ti
c disturbances will be
unstable and may even cause large errors.
Do not use when the appearance of the meter or the test pen is broken.
If the meter is not used correctly, the safety func
ti
ons provided by the meter may fail.
Care must be taken when working around bare conductors or buses.
Do not use this instrument near explosive gas vapor or dust.
The correct input func
ti
on must be used to measure the range.
The input value must not exceed the limit of the input value speci
fi
ed for each range to
prevent damage to the instrument,
Do not touch the unused input when the instrument is connected to the circuit under test.
When the measured voltage exceeds 60 Vdc or 30 Vac, use cau
ti
on to prevent electric shock.
When measuring with a test pen, place your
fi
nger behind the guard ring of the test.
Before conver
ti
ng the range, it must be ensured that the test pens have le
ft
the circuit under
test.
Before carrying out a resistance, diode, capacitance measurement or con
ti
nuity test, the
circuit under test must be powered o
ff
and all high-voltage capacitors in the circuit under
test should be discharged.
Do not measure the resistance on a live circuit or perform buzzer test.
Before conduc
ti
ng the current measurement, the fuse of the meter should be checked.
Before connec
ti
ng the meter to the circuit under test, the power of the circuit under test
should be turned o
ff
.
When performing TV repairs or measuring power conversion circuits, care must be taken in
the high-amplitude voltage pulses in the circuit under test to avoid damage to the meter.
The instrument uses three pieces AA 1.5V ba
tt
eries to power the ba
tt
ery. The ba
tt
ery must
be properly installed in the ba
tt
ery compartment of the meter.
When the ba
tt
ery with low voltage symbol
appears, replace the ba
tt
ery immediately.
Insu
ffi
cient ba
tt
ery power can make the meter read incorrectly, which may result in electric
shock or personal injury.
When measuring voltages, do not exceed 600V. Do not use the instrument when the
instrument's housing or part of the housing is removed.
Maintenance:
When opening the instrument case or removing the ba
tt
ery cover, pull out the test pen
fi
rst.
The speci
fied
replacement parts must be used to service the meter.
Before opening the meter, all relevant power must be disconnected. At the same
ti
me,
you must ensure that you do not have sta
ti
c electricity to avoid damage to the meter.
Instrument components, instrument calibra
ti
on and maintenance opera
tio
n
instruc
ti
ons are operated by professionals.
When opening the instrument housing, some capacitance in the instrument must be
no
ti
ced. Even a
ft
er the instrument is turned o
ff
, dangerous voltages are kept.
If the instrument is observed Any abnormality, the table should be immediately
stopped and sent for repair, and to ensure that it can not be used before inspec
ti
on
quali
fi
ed.
When not in use for a long
ti
me, please remove the ba
tt
ery, and avoid storing in high
temperature and humidity.
Input protection measures
The limit voltage is 600V when the voltage is measuring.
The limit voltage is 250 Acv or the equivalent RMS voltage when the frequency,
resistor ,buzzer or the diode is measuring.
The fuse (F200mA/250V)will work to protect when the uA and mA is measuring.
General maintenance
In order to avoid electric shock or damage to the instrument, it cannot be the inside
of the instrument. Before opening the housing or the battery cover, the connection of the
test meter and the input signal must be removed.
Periodically use a damp cloth and a small amount of detergent to clean the meter housing. Do
not use abrasives or chemical solvents. Input sockets, if soiled or wet, may a
ff
ect readings.
