1. 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.

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 4.8V, 7.2V, 9.6V, 12V or 24V batteries or a DC power source
from 7V 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. Refer
to opto-LINK (Optional) page 16 for more information.
The instrument comes with five different firmware types (K342, K344, K346, K354, and K356).
FACTRY.APP.ID can be used to select desired firmware. Then licence code should be entered using
FACTRY.L.CODE. Refer FACTRY menu page 41 for more information.
1.1. Overview
This instrument provides ZERO and TARE functionality as well as more setup options (e.g.
serial and setpoints) and printing functionality.
It also supports special functions (e.g. 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 (e.g. ZERO, TARE, CLOCK, etc.), are retained when power is removed.
(NVRAM only supported in the K35* models)
This instrument has two isolated transistor outputs with status display 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.
