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.
Measurement Categories
These digital oscilloscopes can make measurements in measurement category I (CAT I).
Do not exceed a voltage input of more than 5 V absolute value for a 50 Ω impedance input or 400 V
absolute value for a 1 MΩ impedance input.
i
This oscilloscope can only be used for measurements within its specified measurement category.
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 120 V RMS or 240 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 threeconductor AC line power cable. The power cable must be plugged into an approved threeconductor 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 properlygrounded 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 flammable atmosphere.
Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finelydivided particulates.
ii
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 10 °C to 40 °C and the operating humidity is ≤ 85 % relative humidity at 40 °C,
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
iii
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.
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.
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.
iv
Cooling fans
This instrument contains one or more cooling fans. For continued safe operation of the instrument,
the air inlet and exhaust openings for these fans must not be blocked nor must accumulated dust
or other debris be allowed to reduce air flow. Maintain at least 25 mm clearance around the sides
of the instrument that contain air inlet and exhaust ports. If mounted in a rack, position power
devices in the rack above the instrument to minimize instrument heating while rack mounted. Do
not continue to operate the instrument if you cannot verify the fan is operating (note some fans
may have intermittent duty cycles). Do not insert any object into the fan's inlet or outlet.
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.
Do not pull the instrument with the power cord, connected probe, or connected test lead.
Do not move the instrument when a probe is connected to a circuit being tested.

Connect the Probe
B&K Precision provides passive probes for the 2560 Series oscilloscope. Please refer to the
probe’s user manual for more detailed information. Before connecting probes, please read and
understand the Probe Safety section.
Table 5 Analog Probes
Connect the BNC terminal of the probe to one of the channel BNC connectors on the front panel
(see the safety information below). Connect the probe tip to the circuit point under test and the
ground alligator clip of the probe to a grounded point in the circuit.
Probe Compensation
All oscilloscope probes should be properly compensated before their first use with the
oscilloscope. A non-compensated or inadequate compensated probe can cause inaccurate
measurements. The following steps illustrate the proper probe compensation procedure.

3. Connect the probe to channel 1's BNC connector. Connect the tip of the probe to the
compensation signal output terminal.
4. Press the Auto Setup button.
5. Observe the waveform on the screen and compare it to the following figure.
Figure 12 -Waveform compensation
6. Use a nonmetallic flat-head screwdriver to adjust the low-frequency compensation
adjustment screw on the probe until the waveform matches the “Correctly compensated”
waveform above.
We recommend you check probe compensation daily or after the probe has been used on
another instrument.
Probe Safety
A guard around the probe body provides a finger barrier for protection from electric shock.

Figure 13 – Oscilloscope probe
WARNING: SHOCK HAZARD
To avoid electric shock when using the probe, please make certain that the insulated wire of
the probe is in good condition and do not touch the metallic parts of the probe when it is
connected to a high voltage.
Do not connect the probe's ground lead (e.g., using the supplied alligator clip) to any point in
a circuit that is not at ground potential. If you're not sure whether a point you want to
connect to is at ground potential, first check it with a known-working high-impedance digital
voltmeter.
Connect the probe to the oscilloscope and connect the ground terminal to ground before you
take any measurements.
Probe Attenuation
Probes have attenuation factors that can affect the vertical display of the signal. Before making
measurements with the probe, verify the probe's attenuation matches the attenuation setting of
the oscilloscope channel it is connected to. Push the numbered button corresponding to the
channel the probe is connected to and ensure the attenuation factor shown on the Probe softkey
matches that of the probe. Failure to do this will result in significant measurement error.
