Safety Summary
The following safety precautions apply to both operating and maintenance personnel and must be followed
during all phases of operation, service, and repair of this instrument.
Before applying power to this instrument:
Read and understand the safety and operational information in this manual.
Apply all the listed safety precautions.
Verify that the voltage selector at the line power cord input is set to the correct line voltage. Operating
the instrument at an incorrect line voltage will void the warranty.
Make all connections to the instrument before applying power.
Do not operate the instrument in ways not specified by this manual or by B&K Precision.
Failure to comply with these precautions or with warnings elsewhere in this manual violates the safety
standards of design, manufacture, and intended use of the instrument. B&K Precision assumes no liability for a
customer’s failure to comply with these requirements.
Category rating
The IEC 61010 standard defines safety category ratings that specify the amount of electrical energy available
and the voltage impulses that may occur on electrical conductors associated with these category ratings. The

3
category rating is a Roman numeral of I, II, III, or IV. This rating is also accompanied by a maximum voltage of
the circuit to be tested, which defines the voltage impulses expected and required insulation clearances. These
categories are:
Category I (CAT I): Measurement instruments whose measurement inputs are not intended to be connected to
the mains supply. The voltages in the environment are typically derived from a limited-energy transformer or a
battery.
Category II (CAT II): Measurement instruments whose measurement inputs are meant to be connected to the
mains supply at a standard wall outlet or similar sources. Example measurement environments are portable
tools and household appliances.
Category III (CAT III): Measurement instruments whose measurement inputs are meant to be connected to the
mains installation of a building. Examples are measurements inside a building's circuit breaker panel or the
wiring of permanently-installed motors.
Category IV (CAT IV): Measurement instruments whose measurement inputs are meant to be connected to the
primary power entering a building or other outdoor wiring.
Do not use this instrument in an electrical environment with a higher category rating than what is specified in
this manual for this instrument.

4
You must ensure that each accessory you use with this instrument has a category rating equal to or higher than
the instrument's category rating to maintain the instrument's category rating. Failure to do so will lower the
category rating of the measuring system.
Do not operate in an explosive or flammable atmosphere
Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finely-divided
particulates.
The instrument is designed to be used in office-type indoor environments. Do not operate the instrument
In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or finely-divided
particulates.
In relative humidity conditions outside the instrument's specifications.
In environments where there is a danger of any liquid being spilled on the instrument or where any
liquid can condense on the instrument.
In air temperatures exceeding the specified operating temperatures.
In atmospheric pressures outside the specified altitude limits or where the surrounding gas is not air.
In environments with restricted cooling air flow, even if the air temperatures are within specifications.
In direct sunlight.

5
This instrument is intended to be used in an indoor pollution degree 2 environment. The operating
temperature range is 0 °C to 40 °C and the operating humidity range is ≤95%relative humidity with no
condensation allowed.
Measurements made by this instrument may be outside specifications if the instrument is used in non-office-
type environments. Such environments may include rapid temperature or humidity changes, sunlight, vibration
and/or mechanical shocks, acoustic noise, electrical noise, strong electric fields, or strong magnetic fields.
Do not operate instrument if damaged
If the instrument is damaged, appears to be damaged, or if any liquid, chemical, or other
material gets on or inside the instrument, remove the instrument's power cord, remove the instrument from
service, label it as not to be operated, and return the instrument to B&K Precision for repair. Notify B&K
Precision of the nature of any contamination of the instrument.
Clean the instrument only as instructed
Do not clean the instrument, its switches, or its terminals with contact cleaners, abrasives, lubricants, solvents,
acids/bases, or other such chemicals. Clean the instrument only with a clean dry lint-free cloth or as instructed
in this manual.
Not for critical applications

6
This instrument is not authorized for use in contact with the human body or for use as a component in a life-
support device or system.
Do not touch live circuits
Instrument covers must not be removed by operating personnel. Component replacement and internal
adjustments must be made by qualified service-trained maintenance personnel who are aware of the hazards
involved when the instrument's covers and shields are removed. Under certain conditions, even with the power
cord removed, dangerous voltages may exist when the covers are removed. To avoid injuries, always
disconnect the power cord from the instrument, disconnect all other connections (for example, test leads,
computer interface cables, etc.), discharge all circuits, and verify there are no hazardous voltages present on
any conductors by measurements with a properly-operating voltage-sensing device before touching any
internal parts. Verify the voltage-sensing device is working properly before and after making the measurements
by testing with known-operating voltage sources and test for both DC and AC voltages. Do not attempt any
service or adjustment unless another person capable of rendering first aid and resuscitation is present.
Do not insert any object into an instrument's ventilation openings or other openings.
Servicing

7
Do not substitute parts that are not approved by B&K Precision or modify this instrument. Return the
instrument to B&K Precision for service and repair to ensure that safety and performance features are
maintained.
For continued safe use of the instrument
Do not place heavy objects on the instrument.
Do not obstruct cooling air flow to the instrument.
Do not place a hot soldering iron on the instrument.

Section 1 General Description
1.1 INTRODUCTION
B&K Precision Battery Capacity Analyzer Model 601B measures the terminal voltage, internal resistance, and percent of charged capacity
left in a battery.
The model 601B supports 6V & 12V storage type lead acid batteries with wide range of Ah capacity. No external power (Mains or DC) is
required. The unit works on the BUT (Battery Under Test) power.
1.2 APPLICATIONS
As the information age develops it is likely that the demand for UPS units will increase for use in hospitals, offices, labs etc. It is expected that
the importance of battery maintenance will increase along with increasing demand for UPS.
The 601B can be applicable for Automobile Service Stations, UPS Manufacturing, Maintenance and Field Servicing, QC Department, Battery
Systems in Railways, Telecommunications, Ships / Submarine.
