BST100 MANUAL
1．Brief Introduction
The ANCEL BST100 battery tester is used for testing the conditions of the 12V lead-acid starting
battery: cranking system and charging system.
It comes with a large backlight LCD screen and it supports classic touch-tone to help you read and
operate more efficiently. It utilizes the 4-wire Kelvin method to complete the collection of a series of
complicated data for calculating every testing data with a build-in precise circuit and improved
digital processor. Moreover, some circuit improvements including polar reversal protection,
over-voltage input protection, and loose lead detection, ensure safety and convenience during
testing.
This is a must-have in the fields of battery sales, vehicle repair and
battery inspection equipment system.
2．Safety Rules and Precautions
This manual includes operation instruction and warning.
Damage to the meter may occur if it is not operated following the rules in this manual. This tester is
designed and produced strictly according to IEC/EN61010-1 safety standard. Also, it reaches
double insulation over-voltage standard CATⅢ 600V and pollution degree 2.
(1) The working voltage is DC 9V to 18V.
(2) The voltage value will be higher than 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 drops to the normal value.
(3) Check the insulating layer of the clamps before testing. It can only be operated without any
damage, bareness or disconnection. Do not use it when the housing is not covered completely
or correctly, which will cause electric shock.
(4) Do not use or store the tester in the condition of high temperature, high humidity, combustibility,
explosion, and strong electromagnetic field.
(5) Do not modify the internal circuit in order to avoid damage to the tester and danger to the user.
(6) Wear proper eye mask when testing or repairing in order to avoid objects hitting eyes from the
engine.
(7) Keep the site ventilated when testing or repairing in order to avoid inhaling toxic gas.
(8) When the engine is running, do not place the tester or accessories besides the engine or the
exhaust pipe in order to avoid damage by high temperature.
(9) Pay attention to the precautions and maintenance procedure from the manufacturer during
repairing.
(10) Standard of optional storage battery:
CCA：100~2000 IEC：100~1400
BCI： 100~2000 EN：100~2000
