i310s

AC/DC Current Clamp

Instruction Sheet

Introduction

The i310s Current Clamp (“Clamp”) has been designed for use with oscilloscopes and digital multimeters for accurate nonintrusive measurement of ac, dc and complex waveform currents.

Using advanced Hall Effect technology, the Clamp can accurately measure currents up to 450 A peak over the frequency range of dc to 20 kHz. These features make it a powerful tool for use in inverters, switch mode power supplies, industrial controllers, automotive diagnostics, 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.

WX Warning

The Clamp 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 Clamp if damaged. Always

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

• Always ensure the Clamp is removed from any

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

• Use the Clamp only as specified in the

operating instructions; otherwise the 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 Clamp anywhere beyond the

tactile barrier.

• Before each use, inspect the Clamp. Look for

cracks or missing portions of the 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.

• 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.

• Do not use Clamp in wet environments or in

locations that hazardous gases exist.
