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.

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.

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.

Connection of the 9832 or 9833 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: 9832: 2500 VA; 9833: 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

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 as short as
possible. The local sense is the default configuration. When remote sense is selected, both
