Warnings and Precautions

PLEASE READ SPECIFICATIONS BEFORE OPERATING THE INSTRUMENT

Exceeding the maximum limits of this instrument is DANGEROUS.

Exceeding these limits will expose you to physical injury or even death and will

almost certainly damage your instrument. Even low-level voltages and currents

are capable of causing serious injury or even death.

Please do not use this or any piece to test equipment without proper

•

training.

Individual functions and ranges have different overload limits.

•

It is VERY IMPORTANT that you make yourself aware of these overload

•

limits.

Check the specifications of these overload limits.

Introduction

The CT238A current probe has been designed for use with multimeters for

accurate, non-intrusive measurement of both AC, DC and complex waveform

currents.

Using advanced Hall Effect technology the CT238A can accurately measure

currents with a resolution of 1mA from 5mA to 30 Amps 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 and other applications requiring current

measurement and/or waveform analysis.
