GENERAL SPECIFICATIONS
The Klein Tools ET600 is a digital tester with four voltage ranges for
insulation resistance measurements, and is also a True Root-Mean-
Squared (TRMS) tester that measures AC/DC voltage, electrical
resistance, and continuity.
• Operating Altitude: 6562 ft. (2000m)

Double insulation
CAT III: Measurement category III is applicable to test and
measuring circuits connected to the distribution part of the
building's low-voltage MAINS installation.
CAT IV: Measurement category IV is applicable to test and
measuring circuits connected at the source of the building's
low-voltage MAINS installation.
• Electromagnetic Environment: IEC EN 61326-1. This
equipment meets requirements for use in basic and controlled
electromagnetic environments like residential properties,
business premises, and light-industrial locations.
