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.Ill 1000V over-voltage safety standards and
pollution level 2.
ill 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.
•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.
•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
Safety Operating Procedures
•Before opening the outer cabinet or battery cover, please remove the probe on
the instrument. Do not use the instrument in the circumstances that the
instrument is taken apart or battery cover is opened.
•When using the probe, please put your fingers behind the finger protector of the
probe.

•When measuring, please connect the zero line or the ground line firstly, then
connect the live wire; but when disconnecting, please disconnect the live wire
firstly, then disconnect the zero line and ground line.
•When it shows low battery indicator, please replace the battery in time in case of
any measurement error.
•It only meets the safety standards when the instrument is used together with the
supplied probe. If the probe is damaged and needs to replace, the probe with
same model number and same electrical specifications must be used for
replacement.

Cautions
•Do not usethe instrument around explosive gas, steam or inwet environment.
•The instrument shall be used in accordance with the specified measurement
category, voltage or current rating.
•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.
