General Description
This meter has been designed to be simple to configure. It is easy to use because
no menu is used. Look at the front panel below... to adjust ZERO you press the
ZERO button, to adjust Span you press the SPAN button, to adjust Alarms you
press the ALARM button. There is no need to spend time learning a complex
menu system.
The meter’s main function is to totalise (or integrate) from a linear millivolt
signal, typically from a DC current shunt. This meter can accept shunts with
50mV, 60mV, 75mV and 100mV outputs.
The meter can give alarm outputs, scaled and isolated analogue output and isolated
serial data retransmission when fitted with appropriate plug-in option boards.
Alarm outputs 2 and 4 give pulsed outputs of 100mS, each time a batch total has
been reached.
The front panel has a 6 digit, 7 segment window for displaying the measurement.
It allows decimal point and minus sign characters to be included and has 4
alarm annunciators to show the status of each alarm relay.
The front panel pushbuttons each have an LED to show which setting is being
altered at any time.
A lockout switch on the rear of the meter saves your configuration settings in
non-volatile memory, which has a 10 year guaranteed storage period. If the lockout
switch is not set ON, your settings could be accidentally altered.
