Safety Summary

WARNING CAUTION

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 instrument.

Only qualified personnel should use this probe. This

high 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.

This instrument is intended for usage within

Measurement Category I (CAT I) only.

Do not exceed 60 seconds of contact with high

voltage. When making contact between this probe and

any circuit with voltages ≥8 kV DC, ≥5 kVrms AC, or ≥15

kVpk-pk AC, wait for 5 minutes between such

measurements.

Do not work alone when working with high voltages.

Do not apply to the input any potential that exceeds

the maximum rating of the probe.

For your own safety, inspect the probes for cracks and

frayed or broken leads before each use. If defects are

noted, DO NOT USE the probe.

Hands, shoes, floor and work bench must be dry.

Avoid making measurements under humidity,

dampness or other environmental conditions that might

affect safety.

Turn the high voltage source off before connecting or

disconnecting the probe whenever possible.

The probe body should be kept clean and free of any

conductive contamination.

Do not remove the probe casing. Removal of the

probe’s casing may expose you to electric shock.

Keep fingers behind the probe’s finger guard during

use.

Always properly ground the probe with the lead before

contacting high voltage circuits with the probe tip. Always

disconnect the probe tip from high voltage circuits before

disconnecting the ground lead. Do not connect the probe

ground lead to any point which is at a potential other than

earth ground.

Use only on test instruments where the chassis or

return lead is properly grounded.

Use only in office-type indoor setting

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 environments where there is a danger of any

liquid being spilled on the instrument.

• In air temperatures exceeding the specified

operating temperatures.
