Dear Client

Thank you for Purchasing our

HT2672 Insulation 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

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!
