7.0 SIGNAL AND POWER INPUT CONNECTIONS
7.1 Introduction
The following describes how to connect your sensors to your meter with and without sensor excitation and how to connect
the AC power to your meter. Prior to wiring the sensor to the meter, check with a multimeter that a proper excitation
exists.
WARNING: Do not connect ac power to your meter until you have completed all input and output connections.
Failure to do so may result in injury! This device must only be installed electrically by specially trained
electrician with corresponding qualifications.
Earth ground MUST be connected to the same earth ground used by the signal source, in order to achieve
published stability and accuracy specifications.
7.2 Signal Input Connections - Process
The following Figures (7-1 through 7-5) show the connections for voltage, current and potentiometer inputs:
