Values Measured In Balanced Three Phase Mode And Single Phase Mode - Circutor C-80 Instruction Manual

-------------- SYSTEM ANALYZER
3.1.- Values measured in balanced three phase mode and single phase
mode
In three phase mode, the three phases must be connected in the correct fashion plus
a current clamp to measure current. The C-80 measures power consumed.

This manual has information and warnings that the user must follow to ensure
the safe operation of the equipment and to maintain it in good condition in
terms of safety.
If the equipment is used in a way not specified by the manufacturer, the
equipment's protection may be compromised. Bear in mind that when the

dangerous parts.
If it is likely that there has been a loss in protection (for example if there are
visible signs of damage) the equipment must not be handled. In this event
please contact a qualified service representative.
