Safety Specificatio
/A\Warning
To avoid possible electric shock or personal injury, please observe the following
specifications:
© Please read this manual carefully and pay special attention to safety waring information before
using the meter.
® Operate the meter according to the manual, otherwise the protection function provided by the
instrument may be damaged or weakened.
® Take special care when measuring values that above 60V dc, 30V ac RMS, 42V peak. This kind of
voltage has the danger of electric shock.
® Do not measure voltage higher than the rated value between terminals or between terminals and
ground.
® Measure the known voltage to check whether the meter works normally. If it is not normal or
damaged, please do not use it again.
© Before using the meter, please check whether there are cracks or damaged plastic parts in the
instrument shell. If so, please do not use it again.
© Before using the meter, please check whether the probe is cracked or damaged. If so, please
replace the probe with the same model and electrical specification.
® Please use the meter according to the measurement category, voltage or current rating specified in
the meter or manual
@ Please observe local and national safety regulations. Wear personal protective equipment (such as
EN
1

approved rubber gloves, masks and flame retardant clothing, etc.) to prevent injury caused by
electric shock and electric arc when dangerous live conductors are exposed.
© When the "{C§ " symbol is displayed on the meter, please charge battery in time to prevent
measurement error.
© Do not use the meter in the environment with explosive gas or steam or humid environment.
® When using the probe, please hold your fingers behind the probe finger guard.
® When measuring, please connect the null or ground wire first, then the live wire; when
disconnected, please disconnect the live wire first, and then the null or ground wire.
® Remove the probe from the meter before opening the case or battery cover. Do not use the meter
when the meter is disassembled or the battery cover is opened.
® The meter can only be used together with the probe provided to meet the requirements of the
safety standard. If the probe is damaged and needs to be replaced, the probe of the same model
and electrical specification must be replaced.
