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 specied 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 denes 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 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 denes 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 specied in this manual
for this instrument.
3
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.
Electrical Power
This instrument is intended to be powered from a CATEGORY II mains power environment. The mains power should be
115 V RMS or 230 V RMS. Use only the power cord supplied with the instrument and ensure it is appropriate for your
country of use.
Ground the Instrument
To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical safety ground. This
instrument is grounded through the ground conductor of the supplied, three-conductor AC line power cable. The power
cable must be plugged into an approved three-conductor electrical outlet. The power jack and mating plug of the power
cable meet IEC safety standards.
Do not alter or defeat the ground connection. Without the safety ground connection, all accessible conductive parts
(including control knobs) may provide an electric shock. Failure to use a properly-grounded approved outlet and the
recommended three-conductor AC line power cable may result in injury or death.
Unless otherwise stated, a ground connection on the instrument’s front or rear panel is for a reference of potential only
and is not to be used as a safety ground. Do not operate in an explosive or ammable atmosphere.

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 qualied 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 rst aid and resuscitation is present.
Do not insert any object into an instrument’s ventilation openings or other openings.

Getting Started
2.1 Input Power and Fuse Requirements
The supply has a universal AC input that accepts line voltage input within:
Voltage: 100 - 240 VAC (+/- 10 %)
Frequency: 50/60 Hz
Input Power: 60 VA MAX.
Before connecting to an AC outlet or external power source, be sure that the power
switch is in the OFF position. Verify that the AC power cord, including the extension line,
is compatible with the rated voltage/current. Once veried, connect the cable rmly.
The included AC power cord is safety certied for this instrument operating in rated range. To
change a cable or add an extension cable, be sure that it can meet the required power ratings
for this instrument. Any misuse with an uncertied AC power cord will void the warranty.
SHOCK HAZARD:
The power cord provides a chassis ground through a third conductor. Verify that your power
outlet is of the three-conductor type with the correct pin connected to earth ground.

• Check and replace fuse if necessary (see Table 2.1 - Fuse Table).
Figure 2.1 Fuse Removal
Disconnect power from the instrument when removing and installing fuses.
Any disassembling of the case or changing the fuse not performed by an
authorized service technician will void the warranty of the instrument.
Getting Started 16
2.4 Theory of Operation
The BA8100 stimulates the DUT using a small amplitude and a precisely timed alternating current signal. The unit
compares the reference signal and the response signal. By measuring the current and voltage signal at various frequencies,
a spectrum of internal impedance is derived.
2.5 Connections
Figure 2.2 Front Panel
The unit uses 4 connections: "Input" (positive and negative) and "Sense" (positive and negative). The provided Kelvin
test leads are color coordinated to simplify connections.
2.6 Input
The "Input" connection carries the test current. “Input” consist of the lower pair of connectors, which can be dierentiated
by grey highlighting rings. The grey rings indicate the banana plugs with a gray shroud are connected there.
2.7 Sense
“Sense” consist of the upper pair connectors. It senses the signal at the connecting point. They do not carry current,
which helps eliminate the inuence of the cables on the measurement values.
Measurement Modes
The BA8100 contains two measurement modes: primary mode and secondary mode. To enter primary and secondary
mode press the button then press the button. The letter m can be seen in to top right side of the
screen. The m species the current mode state. If blinking "M" is displayed the instrument is in secondary mode. If the
blinking "m" is displayed, then the instrument is in primary mode. In Figure 5.1 we can see the unit is in primary mode
Figure 3.1 Primary Measurement Mode

Table 3.1 Measurement Modes
Measurement Setup
Follow the instructions in 2.5 to ensure cabling will not have a major impact on the measurements.
Note:
The sweep function as well as plot functions are only available through the BK-FRA software.
Only the measurements listed in Chapter 3 can be obtained through the unit’s display.
The following settings may be entered either through the front panel or through the remote interfaces.
4.1 Setting DC Current Level
The DC current component denes the load applied to the battery. Measurements of a battery at dierent test currents
provides more information about the battery. Dierent load currents may be necessary depending on the size of the
battery.
1. Press the button then press .
2. Enter the load current using the numeric keypad.
3. Press the button to conrm the set value.
4.2 Setting AC Current Level
The AC current component stimulates the battery. The amplitude of this signal is critical for accurate measurement
of the battery internal resistance. This value is directly related to the measureable voltage generated by the battery’s
internal resistance. Therefore, batteries with smaller internal resistance value require larger AC current test. For larger
internal resistances a large test signals will generate a large voltage signal. The input gain of the system needs to change
depending on the signal level.
1. Press the button then press .
2. Enter the AC stimulus current using the numeric keypad.
3. Press the button to conrm the set value.
Note:
The AC current level should be set to approximately 10% of the set DC Current level.
Measurement Setup 19
4.3 Setting Frequency and Sweep
It is standard to test batteries at 1KHz. However, measurements across a range of frequencies provide more information
than a single resistance measurement (at steady state or DC loading). To test across a range of frequencies use sweep
mode. Sweep mode is only available through the software provided.
4.3.1 Single Frequency
1. Press the button then press .
2. Enter the AC frequency using the numeric keypad.
3. Press the button to conrm the set value.
4.3.2 Sweep Mode
To access sweep mode use the BK-FRA software. More information on installing the software in chapter 6.
Figure 4.1 demonstrates the congurable parameters in sweep mode.
Figure 4.1 Software Sweep Mode
• Start: Set the starting frequency of the sweep.
• Stop: Set the stopping frequency of the sweep.
• Step: Set the steps in the sweep. Only available in Control Panel
when Lin mode is set.
• dB: Set the start and stop frequency for a logarithmic sweep.
• Lin: Set the start, stop and step frequency for linear sweep.
• List: Create a custom sweep. A separate window will open allowing the
user to customize up to 40 steps in a sweep. See gure 4.2
• DC-SWEEP: Performs multiple frequency sweeps at user-dened load levels set
in Edit (10 sweeps max).
• LOG: Save the recorded data to selected path.
A sweep yields more information about the DUT. The data collected can be graphed and recorded. See section 6 for
details on how to graph the sweep and record the data.
Figure 4.2
Software List Mode
Measurement Setup 20
Note:
As frequency increases, the physical arrangement of the test leads has a greater impact. Reduce the loop area
created by the test leads when working at higher frequencies to reduce the inductance of the cabling.
4.4 Making a Measurement
Once the appropriate stimulus values have been specied, connect the battery. Press to enable the load and the
stimulus signal. Press the button to cycle between the dierent measurement modes. See section 3 for more
details.
To take measurements using the sweep function see section 6.4.
Note:
Once you obtain a measurement press the button to disable the load
and the stimulus signal. This prevents the battery from being discharged.
Verication Test
Figure 5.1 Self-Test Fixture
The Self-Test Fixture (TLC81) serves two functions: it veries the BA8100 meets the accuracy and resolution specications, and is used as a reference when a user calibration is conducted. A user calibration is a compensation procedure
used to reduce the impedance introduced by the test leads. It does not issue data to create a report or certicate of
calibration that conrms conformance with its specifcations.
The user calibration procedure can be completed to the front panel or to the test leads. The BA8100 uses a single
memory location to store the compensation data. This memory will be over written each time the user calibration is
completed. Therefore, prior to conducting a verication test the user calibration procedure must be completed to the
front panel.
Note:
Out of the box the compensation data stored in the memory will be for the front panel. It is
recommended a verication test is conducted to ensure the instrument is working as expected.
The Verication Procedure should be completed when the user has concerns with user calibration to the test leads
or if there is doubt about the the instrument’s calibration. If the Verication Procedure to the Front Panel does
not provide conforming result after completing a user calibration to the front panel, the unit must be sent back to be
calibrated.
Verication Test 22
5.1 Verication Procedure
The verication procedure can be conducted to the front panel or to the test leads. Verication to the test leads should
be completed when there is a change in the position of the leads that can aect the impedance. Changes in looping,
tension, or enviromental pararemeters of the test leads can cause the compensation values to become obsolete.
If after completing a user calibration to the test leads the verication test to the leads is still failing, the next step is to
complete a user calibration to the front panel and conduct the verication procedure to the front panel. If the verication
to the front panel also fails the BA8100 will have to be sent in for repair and calibration.
Note:
The BA8100 along with the TLC81 when must be shipped together when sent in for repair or calibration.
Materials Required
• BA8100
• TLC81, Self-Test Fixture with matching serial number to the BA8100
• Power supply
– Any power with an output of 5 V and 3A is required.
Note:
The TLC81 is matched to the BA8100 by the manufacturer. If the TLC81 serial
number does not match the BA8100 serial number conctact the distributor.

Figure 5.4 Verication-Test to Test Leads
4. Connect the power supply to the TLC81’s power input.
5. Set the power supply’s voltage to 5 V and its current to set DCI of the BA8100 (Recomended load: .5 A).
6. Enable the BA8100 input and the power supply’s output.
7. If the unit is within calibration and functioning properly it will measure 5.0000 mΩ±(0.5 % of reading + 5 μΩ).
– The BA8100 is calibrated to the front panel. Calibration to the test leads is required in order to meet the
impedance measurement specications.
– Small changes in test lead position as well as environment changes can have an eect on the instrument reading.
The calibration and verication setup must be the same to meet specications. To perform a user calibration to
the test leads refer to section 5.4.1
Verication Test 25
5.4 User Calibration
Conguration of the settings in calibration mode can change the unit’s
measurement accuracy. Only adjustments to the ACA Ratio should be made.
5.4.1 User Calibration to the Test Leads
To a user calibration to the test leads connect the leads front the front panel to the TLC81. Power the TLC81 using a
5 V 3 A source. Before starting the user calibration procedure ensure your setup is complete. Making adjustment to the
setup, such removing the twist in the test leads, will eect the calibration ratios. The setup should be similar to the one
shown in gure 5.5 with adjustments to position of the test leads.
The leads should be laid in the position that will be used for testing.
