Range
0.0 % to 99.9 %

Accuracy
[1]

Within  (0.2 % per kHz + 0.1 %) for rise times <1 s.

Conforms to relevant North American Safety Standards
Conforms to relevant South Korean EMC Standards

CAT II

Measurement Category II is applicable to test and measuring circuits connected directly
to utilization points (socket outlets and similar points) of the low-voltage MAINS
installation.

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.

On page 5, replace Electromagnetic Compatibility and IP Rating with the following, and
remove Shock, Safety Compliance and Certifications and add:
IP Rating .................................................. IEC60529: IP67 (Non-operating)
Safety ....................................................... IEC 61010-1: 600 V CAT IV / 1000 V CAT III, Pollution Degree 2
Electromagnetic Environment ............... IEC 61326-1: Portable
Electromagnetic Compatibility .............. In an RF field of 3 V/M, accuracy = specified accuracy +20 counts, except
600 A dc range total accuracy = specified accuracy +60 counts.
Temperature not specified
