1 Introduction
This manual provides operating instructions for the Crompton Switchboard Integra series of
Digital Metering Systems. Some versions of the Integra incorporate the metering transducer
that provides the interface for the measurement of power supply parameters such as voltage,
current, power, frequency etc. In other versions, the display and transducer are separate,
interconnected units. The display allows the user to set up metering transducer parameters
and to monitor the measurements. Some Integra models can be supplied as either an integral
or display-only version, while others are only available in one format. This manual provides
user instructions.
A separate leaflet provides installation instructions.
Table1 lists the various models of Integra and shows their distinctive characteristics.

Voltage and current readings are true RMS, up to the 15th harmonic (31st for 1560/80
transducer).
The unit can be powered from an auxiliary a.c. or d.c. supply that is separate from the metered
supply. Versions of each model are available to suit 100-250V 45-65 Hz a.c./d.c. and 12-48V d.c
nominal supplies.
