Safety Summary
The following safety precautions apply to both operating and maintenance personnel and must be
observed during all phases of operation, service, and repair of this instrument. Before applying
power, follow the installation instructions and become familiar with the operating instructions for this
instrument.
If this device is damaged or something is missing, contact the place of purchase immediately.
This manual contains information and warnings that must be followed to ensure safe operation as
well as maintain the meter in a safe condition.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical
ground. This instrument is grounded through the ground conductor of the supplied, three-conductor
ac power cable. The power cable must be plugged into an approved three-conductor electrical
outlet. Do not alter the ground connection. Without the protective ground connection, all accessible
conductive parts (including control knobs) can render an electric shock. The power jack and mating
plug of the power cable must meet IEC safety standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes. Operation of any
electrical instrument in such an environment constitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Instrument covers must not be removed by operating personnel. Component replacement and
internal adjustments must be made by qualified maintenance personnel. Disconnect the power
cord before removing the instrument covers and replacing components. Under certain conditions,
even with the power cable removed, dangerous voltages may exist. To avoid injuries, always
disconnect power and discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt any internal service or adjustment unless another person, capable of rendering first
aid and resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY THE INSTRUMENT
Do not install substitute parts or perform any unauthorized modifications to this instrument. Return
the instrument to B&K Precision for service and repair to ensure that safety features are maintained.

1.1 Introduction
This manual contains information requir ed to oper at e t he B&K Pr eci s ion mod el CP62 Current
Probe. This section covers the instrument’s general description, specifications and
characteristics.
1.2 Description
The CP62 current probe allows a g eneral purpose oscilloscope to display AC and DC current signals
up to 100 A Peak (70 A RMS). The CP62 current probe can also make AC and DC measurements
with a multimeter by using the recommended accessory TL62 (BNC-to-banana) plug adapter.

Installation
(Overvoltage)
Category
Terminals on this product may have different installation (overvoltage)
category designations. The installation categories are:
CAT III
Distribution-level mains (usually permanently connected).
Equipment at this level is typically in a fixed industrial location.
CAT II
Local-level mains (wall sockets). Equipment at this level includes
appliances, portable tools, and similar products. Equipment is usually
cord-connected.
CAT I
Secondary (signal level) or battery operated circuits of electronic
equipment.
Pollution Degree
A measure of the contaminates that could occur in the environment
around and within a product. Typically the internal environment inside a
product is considered to be the same as the external. Products should be
used only in the environment for which they are rated.
Pollution Degree 1
No pollution or only dry, nonconductive pollution occurs. Products in this
category are generally encapsulated, hermetically sealed, or located in
clean rooms.
Pollution Degree 2
Normally only dry, nonconductive pollution occurs. Occasionally a
temporary conductivity that is caused by condensation must be expected.
This location is a typical office/home environment. Temporary
condensation occurs only when the product is out of service.
Note: All specifications apply to the unit after a temperature stabilization time of 15 minutes
over an ambient temperature range of 23 °C ± 5 °C. Specifications are subject to change
without notice.
