SCS CTM051 Ground Pro Meter Application Inquiries

Some common questions we received about the CTM051 Ground Pro Meter from SCS are collected below.

  • What is the difference between the SCS CTM051 grounding resistance measuring instrument and a precision multi-meter?

The SCS CTM051 Ground Pro Meter is a comprehensive instrument that measures the ground connection of your equipment in accordance with Grounding standard ANSI/ESD S6.1 and ANSI/ESD S20.20. Measuring ground with a digital multimeter does not comply with ANSI/ESD S20.20 because it measures resistance and not impedance.

  • Is there any more information for using CTM051 to provide accurate measurement of ground impedance?
