1 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 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.

i

Do not use this instrument in an electrical environment with a higher category rating than what
is specified in this manual for this instrument.

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 between 190 V to 250 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 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 flammable atmosphere

ii

Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finely­divided 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.

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 20% to 80% 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.

Not for critical applications

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.

Hazardous voltages may be present in unexpected locations in circuitry being tested when a
fault condition in the circuit exists.

Fuse replacement

Fuse replacement must be done by qualified service-trained maintenance personnel who are
aware of the instrument's fuse requirements and safe replacement procedures. Disconnect the
instrument from the power line before replacing fuses. Replace fuses only with new fuses of
the fuse types, voltage ratings, and current ratings specified in this manual or on the back of the

iv

instrument. Failure to do so may damage the instrument, lead to a safety hazard, or cause a
fire. Failure to use the specified fuses will void the warranty.

Servicing

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.

Connection of the 9832B or 9833B to an AC power source should be made by a
qualified electrician or other qualified personnel. Incorrect wiring may damage the
source or cause a fire hazard.

The included AC power cord is safety certified for this instrument operating in the
rated range. If an extension cable is added, be sure that it can meet the required
power ratings for this instrument. Any misuse with wrong or unsafe cables will
void the warranty.

5 Getting Started

Before connecting and powering up the instrument, please review and go through the
instructions in this chapter.

5.1 Input Power Requirements

The AC input accepts line voltage input within:

Voltage: 190 V – 250 V
Frequency: 47 Hz – 63 Hz
Maximum power consumption: 9832B: 2500 VA; 9833B: 3800 VA
Before connecting to an AC outlet or external power source, make sure that the power switch is

in the OFF position and verify that the AC power cord, including the extension line, is
compatible with the rated voltage/current and that there is sufficient circuit capacity for the
power supply.

Follow the illustrations below to connect the new AC power cord to the AC input of the source
in the rear panel.

5.1.1 North American Split Phase Power

Split phase is commonly used in North American to provide 208 to 240 Volts. This
requires two wires that are both hot. For example 110 V and, 110 V resulting in 220 V
across them. The included cable may be used in most regions by adding a band of blue
electrical tape on each end of the white wire to identify both the black and white with
blue band as hot. The green trace yellow wire is always used for ground and must be
connected properly. Check with your local Authority Having Jurisdiction for clarification.

The power cable that is shipped with the instrument is preassembled from the factory.
The following instruction will provide information for changing the power cable for split
phase.

1. Verify that the source power in your facility can provide the minimum voltage and

10

current required to operate the instrument.

2. Using the power cable provided, identify the end that plugs into the instrument.

Before disassembling the black hooded connector, make a note of how the unit is
assembled from the factory so it can be correctly reassembled.

3. Remove the 4 screws from the bottom of the hooded connector as shown and place

the upper and the upper and lower hood pieces and screws to the side.

The black, white, and green wires should now be clearly visible. Use a screwdriver to
unscrew and release the white wire only.

Add a band of blue electrical tape or heat shrink to each end of the white wire.

1. Return the white wire into the green connecter and tighten the screw. Verify all

three wires are secured in the connector.

2. Closely inspect each of the wires at the enter point of the green connector to

verify none of the copper strands are bridging over to the wrong terminal
causing a short.

3. Carefully reassemble the hood so the Latch Fingers and Caution Label are facing

specified equipment accuracy, please allow the source to warm up for at least 15
minutes.

5.2.3 Power-off Procedure

When the instrument is not in use, make sure to set the front panel power switch to the
OFF position. After the power switch is turned off the internal fans will continue to run
for approximately 5-10 seconds to discharge the internal capacitors per safety
requirements. Once the discharge process is complete, the instrument will carry out an
automatic shutdown process of approximately 2-8 seconds. Do not turn the power back
on until the instrument has completed a full shut down cycle.

5.3 Sense Lines

The source can be configured as local sense or remote sense to compensate the voltage
drop of the test leads. The following diagram shows how to connect the load by local
sense or remote sense configurations.

When local sense is selected, the sense end L is connected to the output end L and
sense end N is connected to the output end N, whereas the output end L is connected to
the load end L and output end N is connected to the load end N. When this sensing
mode is selected, the wires connecting between the sense ends to the load end must be

13

as short as possible. The local sense is the default configuration. When remote sense is
selected, both the sense end L and output end L are connected to the load end L,
whereas both sense end N and output end N are connected to the load end N.

3-Phase kit option (TL983P-KIT)

11 3-Phase Operation

Three-Phase or Multi-Phase operation requires the three 9832B or 9833B AC sources and the 3­Phase kit (model TL983P-KIT) which includes three phase sync modules and two straight
through (pin to pin) RJ45 communication cables for 3-Phase operation. Replacement modules
(model TL983P) are sold separately. Additional phases require additional modules and RJ45
communication cables.

Limitations

9830B Series programming features including step, list, pulse, and amplifier mode are disabled
in 3-phase mode. Several configuration settings (Config 1 and Config 2) remain enabled in 3­phase mode. Range, coupling mode, power on state, and inrush current measurement settings
can be adjusted in 3-phase mode under the Config 1 menu. Under the Config 2 menu, external
reference and transient settings are disabled in 3-phase mode.

11.1 Setup and Configuration

The 9830B Series 3-phase operation uses a master/slave configuration. 3-phase operation
requires three identical 9832B or 9833B models. One AC source will be set to master with the
remaining set to slaves.

1) Rear panel configuration

Power off and disconnect the AC sources from AC input. Connect one TL983P module to
the Digital I/O (DB25) bus connecter to the rear of each AC source using the included
screws and washers to hold them firmly in place. Use a standard Ethernet (RJ45) type
connector to daisy chain modules as shown in the following figure.

40

Do not set more than one AC source to ‘Master’ as this may cause damage or a
malfunction.

RJ45 cables

Master

Figure 11.1: Phase control setting

Additional phases require additional AC sources and TL983P modules.

2) Front panel configuration

After verifying the TL983P adapters are properly wired on the rear panel, the AC sources
must be configured from the front panel. 3-phase operation is enabled by setting the
phase control field on each AC source.

The options for phase control are Master, Slave, or Disable. The master must be set first.
Any one of the three connected AC sources can be set to master. Use the directional key
pad to highlight the phase control field, use the soft key to select master, and press enter
to confirm (Figure 11.1).

The 8-pin digital I/O terminal block on the rear of the
TL983P adapter preserves commonly used signals. See
Table 11.2 for the pin definitions. To insert a wire into
the digital I/O block: press the orange tab in, insert
wire, and release the tab to hold the wire in place.

Digital I/O pinout

Similarly, after setting the master set ‘Phase Ctrl’ of the remaining two AC sources to
‘Slave’. The slaves will automatically connect to the master.

This completes the set-up process for three phase operation.

3) 3-Phase parameters and output

3-Phase parameters include: Voltage (rms), Frequency (Hz), and Phase (deg). The
reference phase of the master is always fixed at 0 degrees. The phase angle of slave
sources can be adjusted from 0 to 359.7 degrees.

The coupling mode can be changed to AC+DC in 3-phase mode to add a positive or
negative DC offset to the AC signal. The DC offset can be set from -424 V to +424 V.

Output of the system is controlled by the master. Enabling/disabling the output of the
master also enables/disables the output of slave instruments.

11.4 Phase Control Software

The 9830B Series Phase control software can be downloaded from bkprecision.com by visiting
the 9830B product page and clicking the ‘Docs & Software’ tab.

Phase control software allows you to easily control 9832B/9833B models in three-phase or
multi-phase modes with data logging and live output monitoring capabilities.

11.4.1 Operation Modes Overview

After launching the Phase Control Software you will be prompted to select ‘Three-Phase
Application Mode’ or ‘Multi-Phase Application Mode’.

The same setting and range limitations that apply to front panel operation also apply
when using the software with the exception of DC offset control.

Three-phase application mode

This mode is intended strictly for 3-Phase Operation using three 9832B or 9833B
models. Setting parameters: Voltage (Vrms), Frequency (Hz), and Range apply to all

The USB interface does not support flow control. The programmer should be
aware of this limitation and pay attention to the Instrument command process
time. If the remote commands are sent too fast the internal buffer may overrun
and cause communication errors. Therefore, it is mandatory to add a delay
between commands so that the Instrument can have sufficient time to process.

12 Remote Interface Operation

The Instrument comes with RS232, USB (USBTMC, and USBVCP), GPIB, LAN and analog
interfaces. Users can program the Instrument using the SCPI (Standard Commands for
Programmable Instruments) commands through any of the remote interfaces. Only one
interface at a time can be enabled and used to control the Instrument.

12.1 Interface Connection

12.1.1 RS232

The RS232 interface can be found on pin 23 (RX) and 11 (TX) of the DB25 port. See the
settings below:

Table 17 - RS232 Settings

Note: RS232 communication is not available in 3-phase mode

12.1.2 USBVCP (virtual COM)

The USB port is a virtual COM port, which can be used for remote communication. See
the settings below:

USBVCP Driver
The USBVCP driver for the SiLabs CP210x used in the unit can be downloaded from the

following link.

53

12.1.3 USBTMC

The USB port is USBTMC-compliant and can be used for remote communication and
control. There are no additional settings in the menu system for USB configuration. The
only requirement is that the USBTMC driver be installed. It is included when installing
VISA software on the computer. (We recommend using NI-VISA, which can be
downloaded at http://www.ni.com/visa/).

12.1.4 GPIB

Each device is assigned a GPIB address from 1-30. To communicate via GPIB, connect a
GPIB cable to the GPIB interface on the back of the instrument and configure the
address.

12.1.5 LAN (Ethernet)

There are three ways to control the Instrument via LAN interface: Web server, Telnet
connection, and Socket connection.

12.1.6 Web server

There is an embedded web server GUI (Graphical User Interface) that can access the
Instrument via LAN interface using a web browser. Using a web browser from a
computer connected to the same local area network as the Instrument. The GUI provides
a simple way to set the voltage and current, and to monitor the output. To use this
function, follow the steps below:
