1.Safety Information
This operation manual includes the safety information related to the operation of the
tester, please read them carefully before using the tester.
Before using the Tester, please read through and understand the operating
manual.
Please keep the Operating Manual properly for future use.
Use the Tester as specified in the Operating Manual.
Please understand in detail the Safety Information section of the manual.
Strictly follow the Safety Information, otherwise it may cause personal injury or
damage to the Tester.
Danger identifies conditions and actions that most likely pose hazard(s)
to the user.
Warning identifies conditions and actions that may pose hazard(s)
to the user.
Caution identifies conditions and actions that may cause minor
injury or damage to the Tester.
Safety sign " "has 3 meanings in this manual, the user has to pay attention to
this sign " " for operation.
Danger
Do not use the Tester around explosive environment, which may cause fire and
explosion.
Do not make any connections when the Tester is wet or the operator's hands
are wet.
Do not apply any voltage beyond the rating or specified range of the Tester.
Do not open battery compartment while testing.
Warning
Do not use the Tester if it is damaged or metal part is exposed.
Do not disassemble the tester randomly. If it needs repair, please contact
our after-sales services or our agents.
Do not change battery or open battery compartment when the Tester is wet.
clean it with dry soft cloth first.
Make sure the Tester is turned off when changing battery or opening the battery
compartment.
Caution
Ensure test leads are inserted into the corresponding port before measurement.
Take the battery out from the Tester if it is not used for a long time.
Do not expose the Tester in extreme temperature and wet environment.
Soft cloth and mild detergent should be used to clean the surface of the Tester
No abrasive and solvent are allowed.
Dry the tester before storing if it is wet.

2. Features
The Tester is designed with intelligent micro-controller chip and offers high accuracy
and reliability. It can measure earth resistance of earth ground devices of electric
power installations, electrical appliances, lightening protection systems, etc, and also
measure earth voltage(It is highly recommended not to use the Tester under severe
outdoor environments such as raining or thunder).
