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.
