1. Brief Introduction

This battery tester is used for lead-acid starting battery, along with

checking the following conditions of the battery, starting up, charging, and

loading. With great design, easy operation, precise reading, complete

functions, this tester supply the readings by a large LCD and hints by sound

and light when testing. It utilizes 4-wire Kelvin method to complete collection

of a series of complicated data for calculating every testing data with build-in

precise circuit and improved digital processor. Moreover some circuit

improvements including polar reversal protection, over voltage input

protection, loose lead detection, ensure safety and convenience during

testing.

So this is the best tool in the fields of battery sales, vehicle repair and

battery inspection in equipment system associated with lead-acid starting

battery.

This manual includes instruction, operation warning and maintenance.

Damage to the meter may occur if failure to operate it complied with

regulations in this manual. This tester is designed and produced strictly

according to IEC/EN61010-1 safety standard. It also reaches double

insulation over voltage standard CATⅢ 600V and pollution degree 2 .

(1) The working voltage of 12V system battery tester is DC 9V to 18V,while

that of 12/24V system refers to DC 9V to 35V. Make sure DO NOT check the

series connection battery.

(2) The voltage value will be higher than that in the normal situation after the

checked battery being fully charged . Please turn on the headlights for 2 to 3

minutes, then check the battery when it's voltage value drop to the normal

value.
