Chapter 1 Introduction 1. 1.1 About This Manual This manual is intended for the user of the PM296/RPM096 Power Quality Analyzer. The PM296/RPM096 is a microprocessor-based instrument used for the measurement, monitoring, management and analysis of electrical parameters. This chapter gives an overview of this manual and an introduction to the PM296/RPM096. Chapter 2, Installation, provides instructions for mechanical and electrical installation.
Remote Display Module - Optional The RPM096 can be equipped with a Remote Display Module (RDM096) that provides local data display as well as setup capabilities. The RDM096 is connected to the RPM096 via a conventional DB15 connector (0.4/1.8/3.0 m cable supplied). The display is multi-page and is composed of three windows with high-brightness digital LEDs. One galvanically isolated direct current voltage input with options 300V, 100V or 20V.
Waveform Recorder for waveform capture and logging on different events. Along with the disturbance monitor it allows for capture and recording of various types of disturbances with a duration from one millisecond and up to tens seconds - transients, outages, sags, surges and deviations in voltage level.
User-selectable options are provided (see Section 4.11): 1) Power calculation mode (P.cAL) 2) Energy rollover value This option specifies the point at which the energy value rolls over to zero. 3) Thermal demand calculation option (thr.d) This option is used to enable or disable thermal power demand calculations.

5.3 Self-Test Diagnostics Display The PM296/RPM096 periodically performs self-test diagnostics during operation. If the instrument fails the test, it discards the last measurement results, and an error code is displayed for one second on all LEDs. Error codes are listed in Table 5-2. Frequent failures may be the result of excessive electrical noise in the region of the instrument. If the instrument resets itself continuously, contact your local distributor.
