Each meter combines the functions of a voltmeter and a clamp-type ammeter. The meters are designed for use in an industrial setting by HVAC/R contractors, building maintenance technicians, MRO (maintenance, repair and operations) personnel at process and power plants, electricians and electrical/electronic technicians.
The only difference between the CM660 and CM700 involves their current measurement range and resolution. Where the CM660 has a 0 to 600A measurement range and a maximum current resolution of 0.01A, the CM700 has a 0 to 1000A measurement range and a maximum resolution of 0.1A.
Both clamp meters are easy to use and ruggedly built. Each meets the ETL CAT III 600V, CAT II 1000V safety standard.
