2000A Flexible AC Current Probe
Instruction Sheet
Introducing the i2000flex
The i2000flex is a flexible AC current probe for use with
oscilloscopes and multimeters. The supplied Dual Banana to BNC
Adapter can be used for connection to instruments with banana
inputs. The i2000flex is optimized for current measurement on thick
and hard to reach conductors.
Unpacking
The following items should be included in the package:
•
i2000flex Current Probe
•
Dual Banana to BNC Adapter (model PM9081/001)
•
Instruction Sheet (this paper)
Check the contents of the shipping box for completeness. If
something in the box has been damaged or missing, contact your
distributor or the nearest FLUKE sales or service office
immediately.
Using the i2000flex Safely
Warning
To prevent electric shock, fire, and personal injury,
carefully read all safety information before
attempting to operate the Current Probe and follow
these procedures.
•
Before each use, inspect the Current Probe and its latching
system for any damage. Pay particular attention to the
insulation surrounding the flexible measuring head.
•
Do not use the Current Probe if it is damaged.
•
Do not use the Current Probe on circuits rated higher than
600V in Installation Category III (See "Specifications",
subsection “SAFETY”.)
•
Do not use the Current Probe to measure bare conductors
carrying a voltage from 30V up to 600V unless you are
wearing protective clothing suitable for high-voltage work.
Always use appropriate equipment for personal protection.
•
Do not expose the i2000flex unit to water.
In this Instruction Sheet, a Warning identifies conditions and
actions that pose hazard(s) to the user. A Caution identifies
conditions and actions that may damage the current probe.
International electrical symbols used are explained below.
