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.
