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.

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.
