User Manual

iv
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.
Probes and Test Leads
 If the instrument is used with test leads or probes, the test leads or probes must have a
safety category rating at least as high as that of the instrument to maintain the
instrument's safety category rating.
 Use only probes that have finger-guards that prevent fingers from slipping down the
probe body and contacting the probe's conductor.
 Inspect the probe or test leads for damage before using them. If you suspect a probe or
test lead is damaged, remove it from service, mark it as unusable, and return to B&K
Precision for maintenance service.
 Do not connect or disconnect test leads or probes from a circuit while that circuit is
connected to a voltage source or may have non-discharged energy storage devices.
 Connect the probe or test leads to the measurement instrument before connecting
them to the circuit to be tested. Disconnect the probe or test leads from the circuit to
be tested before disconnecting them from the measurement instrument.
 For probes that have a voltage reference lead (for example, scope probes with a
"ground lead"), connect the voltage reference lead only to conductors that are at
ground potential.
 Do not use the probe or test leads in a condensing environment or where flammable
materials (for example, dust, chemicals, or vapors) are present.
 Clean the probes or test leads only as instructed in their operating manuals.
Do not operate in an explosive or flammable atmosphere
Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finely-
divided particulates.
The instrument is designed to be used in office-type indoor environments. Do not operate the
