Safety Summary

To avoid personal injury and/or product damage, review and comply
with the following safety precautions. These precautions apply to both operating and
maintenance personnel and must be followed during all phases of operation, service,
and repair of this probe.

A

WARNING

statement calls attention to an operating procedure, practice,
or condition, which, if not followed correctly, could result in injury or death to
personnel.

A

CAUTION

condition, which, if not followed correctly, could result in damage to or destruction
of parts or the entire product.

Do Not Work Alone

Do not work alone when working with high voltages.

Inspect the Probe

statement calls attention to an operating procedure, practice, or

Inspect the probe and accessories for cracks and frayed or broken leads before each
use. If defects or damages are noted, DO NOT USE the probe.

Dry Conditions

Hands, shoes, floor, and work bench must be dry. Avoid making
measurements under humidity, dampness, or other environmental conditions
that might affect safety.

Do Not Remove the Probe’s Casing

Removal of the probe’s casing may expose you to electric shock. If necessary,
disconnect the inputs and outputs of the probe before opening the case.

Hazardous Contact

To avoid injury, remove jewelry such as rings, watches, and other metallic objects. Do
not touch exposed connections and components when power is present.

Unexpected Charges

Hazardous voltages may be present in unexpected locations in circuitry being
tested when a fault condition in the circuit exists.
Capacitors inside the instrument may retain a charge even if the instrument is
disconnected from its source of supply.

Use Only in Office-Type Indoor Setting

The probe is designed to be used in office-type indoor environments.
Do not operate the probe:

•

In the presence of noxious, corrosive, flammable fumes, gases, vapors,
chemicals, or finely-divided particulates.

•

In environments where there is a danger of any liquid

•

In air temperatures exceeding the specified operating temperatures.

•

In atmospheric pressures outside the specified altitude limits or where the
surrounding gas is not air.

Not for Critical Applications

This probe 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 Substitute Parts

Do not install substitute parts or perform any unauthorized modification to the
instrument.

Only Qualified Personnel

Only qualified personnel should use this probe. This differential voltage probe is
designed to be used by personnel who are trained, experienced, or otherwise
qualified to recognize hazardous situations and who are trained in the safety
precautions necessary to avoid possible injury when using such a device.

Observe Maximum Working Voltage

Do not use any probe above its maximum working voltage ranges. See
specifications on page 7.

Use Proper Power Source

Do not operate this probe from a power source that applies more than the voltage
specified.

Must be Grounded

This probe is grounded by the shell of the BNC connector through the grounding
conductor of the power cord of the measurement instrument. Before making
connections to the input leads of this probe, ensure that the output BNC connector is
attached to the BNC connector of the measurement instrument, and that the
measurement instrument is properly grounded. Whenever it is likely that the ground
protection is impaired, you must make the instrument inoperative and secure it
against any unintended operation.
