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 lead is 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 should be used

Dry the tester before storing if it is wet.

Electrical Symbols are used on the Tester or in the manual:

danger, warning, caution double or reinforced insulation

AC Grounding

Conforms to Standards of European Union

2.Features

The Tester is designed with intelligent micro-controller chip to maintain high

accuracy and reliability. It can measure earth resistance of earth ground devices for

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).

● Backlight LCD;

● Battery Check;

● Data Hold& Data Storage(up to 20 sets);

● Auto Power Off;

● Offers Precision Three-Wire & Simple Two-Wire Measurements;

● “- - - - Ω” Indication for Bad Connection to C or E Terminal When Measuring

Earth Ground Resistance;

● “OL” Overloaded Indication;

● Double-or Reinforced-Insulated Structural Design.
