Introduction; Key Features - General CM660 User Manual

INTRODUCTION

Thank you for purchasing General Tools &
Instruments' (General's) CM660 or CM700 Rugged
Auto Ranging True RMS AC/DC Clamp Meter. Please
read this user's manual carefully and thoroughly
before using the instrument.
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.
