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 CT235A and the CT237A current probes have been designed for use with
digital multimeters, recorders and other suitable equipment for accurate
non-intrusive measurement of AC, DC and complex waveform currents. Using
advanced Hall Effect technology the CT237A can accurately measure currents
up to 200 A rms over the frequency range of DC to 10 kHz, while the CT235A
measures currents up to 1000A DC or AC peak. These features make them
powerful tools for use in inverters, switch mode power supplies, industrial
controllers, automotive diagnostics and other applications requiring accurate
isolated current measurement.
