Safety Instructions
The instrument is designed according to the requirements of the
international electrical safety standard IEC61010-1 for the safety
requirements of the electronic testing instruments. The design
and manufacture of instruments strictly comply with the
requirements of IEC61010-1 CAT.III 1000V over voltage safety
standards and pollution level 2.
Warning
In order to avoid possible electric shock or personal injury
and other safety accidents, please abide by the following
specifications:
Please read this manual carefully before using the
instrument, and pay special attention to safety warning
information.
Strictly observe the operation of this manual and use this
instrument. Otherwise, the protection function of the
instrument may be damaged or weakened.
Please be careful if the measurement exceeds 30V AC true
RMS, 42V AC peak or 60V DC. There may be danger of
electric shock at this kind of voltage
By measuring the known voltage to check whether the meter
work is normal, if it is not normal or damaged, do not use it
again.

Before using the instrument, please check whether there is
any crack or plastic damage in the instrument case. If you do,
do not use it again.
Before using the instrument, please check whether the probe
is cracked or damaged. If so, please replace the same type
and the same electrical specifications.
The instrument shall be used in accordance with the
specified measurement category, voltage or current rating.
Please comply with local and national safety code. Wear
personal protection equipment (such as approved rubber
gloves, masks and flame retardant clothes, etc.) to prevent
being damaged by electric shock and electric arc due to
exposed hazardous live conductor
When it shows low battery indicator, please replace the
battery in time in case of any measurement error.
Do not use the instrument around explosive gas, steam or in
wet environment.
When using the probe, please put your fingers behind the
finger protector of the probe.
