Product Overview
The Greenlee CM-660 is a general-purpose AC true-RMS clamp meter for measuring current without opening the conductor and for performing common electrical diagnostic checks with the included test leads. It measures AC current, AC and DC voltage, resistance, continuity, diodes, and frequency, making it useful for troubleshooting circuits, checking equipment, and verifying electrical conditions during installation or maintenance.
A digital low-pass filter supports more stable voltage readings on variable-frequency-drive applications, while the AmpTip feature is intended to improve accuracy on smaller conductors carrying 60 amps or less. The meter also supports minimum, maximum, and average recording, data hold, and two voltage-detection methods: non-contact detection or detection using a single test lead. Select the correct function and measurement category before every test and follow the Greenlee safety instructions.
