Introduction
This instrument is a precision digital indicator using the latest Sigma-Delta analogue to digital
conversion technology to ensure fast and accurate weight readings.
Figure 1: Weight Indicator
The setup and calibration of the instrument are digital, with a non-volatile security store for all setup
parameters.
The instrument may be operated from 9.6V, 12V or 24V batteries or a DC power source from 12V to
24V. There is a soft power on/off function that retains memory of the indicator’s state. Once an
instrument is turned on it will automatically start up again if the external power is interrupted.
The instrument is fitted with opto-LINK communications as standard. This allows a temporary
isolated communications link to be established with a PC using an opto-LINK cable, which enables
software upgrades and the use of computerised setup and calibration via the Viewer software.

Overview
This instrument
provides
ZERO
and
TARE
functionality as well as more setup options (eg.
serial and setpoints) and printing functionality.
It also supports special functions (eg. peak-hold, averaging, counting, etc.), via the user
definable
<FUNCTION>
key. It is equipped with an NVRAM store to ensure day-to-day
operating settings (eg.
ZERO
,
TARE
,
CLOCK
, etc.), are retained when power is removed.
This instrument has three isolated transistor outputs with status display and LEDs on the front
panel as well as the RS-232 communications port that can be used for printer driving or
connection to a remote display or PC. There is a built-in clock for date-stamping printed
outputs.
