2.2 Measurements
2.2.1 Online Voltage and frequency / Phase sequence - AC Voltage
measurement and frequency measurements, phase sequence
 Monitors voltages between L-N, L-PE and N-PE at the same time
 Values shown in real-time
 System can also be used on 3 phase systems for monitoring voltages between
phases
 Phase sequencing should be checked on 3 phase systems.
 System shows values e.g. 1,2,3 or 3,2,1 which relate to the green, blue and brown
test leads to show rotation
