Dear Client

Thank you for Purchasing our

ETCR2000 Clamp Type Earth

Resistance Tester

. Please read the manual in detail prior to first

use, which will help you use the equipment skillfully.

Our aim is to improve and perfect the

company's products continually, so there may be

slight differences between your purchase equipment

and its instruction manual. You can find the changes

in the appendix. Sorry for the inconvenience. If you have further

questions, welcome to contact with our service department.

The input/output terminals and the test column

may bring voltage, when you plug/draw the test wire or

power outlet, they will cause electric spark. PLEASE

CAUTION RISK OF ELECTRICAL SHOCK!
