Battery Voltage and Internal Resistance Tester User Manual
Chapter 1 Introduction
Thanks for using “NEWARE BVIR” voltage internal resistance equipment, in order to make
full use of equipments’ function, please carefully read this user manual before you operate the
testing equipment.
Check the equipment carefully to see weather it was broken during the transportation when
you receive it. Specially, check accessories, panel buttons and connector wire. If there is obviously
damage or can not work in accordance to instructions, please contact NEWARE sales engineer.

Dangerous
This product is designed according to relevant safety standards, and passed the
safety test before the transport. But, wrongly use this instrument will harm the human
body, also damage the equipment. Please confirm your operation is according to the
specifications instructions and using environment before using it. We don't accept any
complaint and feedback of property or personnel damage caused by non-instrument
problem.
Safety Tips
Following instructions in the manual are the relatively important notice and warnings.
“Dangerous” if operation is incorrect, may cause the user very serious injury or death.
“Warning” if operation is incorrect，may cause the user very serious injury or death.
“careful” if operation is incorrect ，may cause the user very serious injury or broke the
equipment.
“Attention” helps improve the performance of the proposed project or the correct operation
of the product of the steps.
1.3 Overpressure Classification
This product meets the class I over-pressure testing product standards。In order to ensure the
safe operation of testing products，IEC 60664 established a safety standards for all types of electric
environment , from the CAT I to CAT IV is divided into 4 categories，called overpressure standard.
They are defined as follows：
CAT I ：The secondary circuit through a transformer or similar circuit connected in AC
socket.
CAT II: The circuit directly connected to the AC power output devices on the circuit
(portable tools, home appliances, etc)
CAT III: The circuit connected to the distribution box on heavy equipment, direct circuit
from distribution box to AC socket.
CAT IV: From lead-in line to aerial lead-in line, electric meter, leakage current protection
equipment (distribution box).
The higher level classification, the corresponding instantaneous electric energy is high also,
so if design a CAT III environmental standard equipment, the instantaneous electric energy it bears
should exceed CAT II standards. There will be a serious accident if testing equipment is over-used
in a higher standard environment, which must be avoided.
