Use and Care Manual
INTRODUCTION
Thank you for purchasing General Tools &
Instruments’ (General’s) DAMP60 or DAMP68
Auto Ranging 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. Both are designed for
use in an industrial setting.
The DAMP60 is designed to be used by HVAC/R
contractors, building maintenance technicians
and electricians.
The DAMP68—with more features (see table
below)—is designed for precise measurement
and analysis of AC/DC power circuits by
process/power plant operators, HVAC/R
contractors and electrical technicians.
The DAMP60 and DAMP68 are easy to use,
ruggedly built and designed for safety. Both
instruments are ETL certified for CAT III 600V use.
