Users Manual

Safety

Designed for measurements on 1000 V Category II Installations, 600 V Category III Installations, Pollution Degree 2, per:

•ANSI/ISA S82.01-1994

•EN61010-1 (1993) (IEC1010-1)

•CAN/CSA-C22.2 No.1010.1-92

•UL3111-1

Max. Input Voltages

Input A and B directly	300 V CAT III
Input A and B via 10:1 probe	1000 V CAT II
	600 V CAT III
METER/EXT TRIG inputs	1000 V CAT II
	600 V CAT III
Max. Floating Voltage
From any terminal to ground	1000 V CAT II
	600 V CAT III
Between any terminal	1000 V CAT II
	600 V CAT III

Voltage ratings are given as “working voltage”. They should be read as Vac-rms (50-60 Hz) for AC sinewave applications and as Vdc for DC applications.

Note

Overvoltage Category III refers to distribution level and fixed installation circuits inside a building. Overvoltage Category II refers to local level, which is applicable for appliances and portable equipment.
