Fluke i30s Operating Manual

i30s/i30

AC/DC Current Clamps

Instruction Sheet

Introduction

The i30s AC/DC Current Clamp has been designed for use with
oscilloscopes and DMMs for accurate, non-intrusive
measurement of both AC, DC, and complex waveform currents.
The i30 AC/DC Current Clamp has been designed for use with
DMMs only. Using advanced Hall Effect technology the i30s can
accurately measure currents with a resolution of 1 mA from 5 mA
to 30 A over the frequency range of DC to 100 kHz. These
features make it a powerful tool for use in inverters, switch mode
power supplies, industrial controllers and other applications
requiring current measurements and/or waveform analysis.

Safety Instructions

Please read this section carefully. It will make you familiar with
the most important safety instructions for handling your product.
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 calibrator or the test
instruments.

W X Warning

The i30s and i30 may only be used and handled by
qualified personnel. To avoid personal injury, follow
these precautions:

• To avoid electric shock, use caution during

installation and use of this product; high
voltages and currents may be present in circuit
under test.

• Do not use the product if damaged. Always

connect probe to display device before it is
installed around the conductor.

• Always ensure the probe is removed from any

live electric circuit, and leads are disconnected
before removing the battery cover.

• Use the Current Probe only as specified in the

operating instructions; otherwise the current
probe’s safety features may not protect you.

• Adhere to local and national safety codes.

Individual protective equipment must be used
to prevent the shock and arc blast injury where
hazardous live conductors are exposed.

• Do not hold the Current Probe anywhere

beyond the tactile indicator.

• Before each use, inspect the Current Probe.

Look for cracks or missing portions of the
Current Probe housing or output cable
insulation. Also look for loose or weakened
components. Pay particular attention to the
insulation surrounding the jaws.

• Use caution when working with voltages above

60 V dc, 30 V ac rms or 42 V ac peak. Such
voltages pose a shock hazard.

• Use of this equipment is designed to protect

against transients in equipment in fixed
equipment installations, such as distribution
panels., feeders and short branch circuits, and
lighting systems in large buildings.

• Use of this equipment in a manner not specified

herein may impair the protection provided by
the equipment.

• CAT III equipment is designed to protect against

the transients in the equipment in fixed
equipment installations, such as distribution
panels, feeders and short branch circuits, and
the lighting systems in large buildings.
