M600 Introduction

The M600 kWh meter comes in a standard DIN 96 x 96 case.
Its mechanical counter is 7 digits long and is non resetable.
When the counter exceeds 9999999 it rolls over to zero.
The M600 can be supplied with a pulsed output allowing it to be connected to remote counters, PLCs data loggers and computers and a mA output proportional to the instantaneous power being measured.
1. Pulsed output.
2. Analogue output of instantaneous power
3. Non standard pulsed width.
4. Calibration at temperature other than 23 °C
5. Calibration at nominal Hz 35 ..... 450 Hz.
