Transmitter WST 3

Quick set-up, calibration
General
Set-up of all parameters in WST 3 can be performed from the control unit by serial
communication, using the programme deltaCOM. Set-up can also be performed from
the transmitter front panel, for example the ‘Quick set-up’ of certain parameters
described in this section.
Calibration is essential to get correct measurement results.
Two calibration methods are available in the ‘Quick set-up’:
Data sheet calibration, for calibration when transducer data are available and
the installation is free from disturbing mechanical forces.
Dead weight calibration, normally the most accurate calibration method,
where known weights are used to give well defined loads on the scale.
Before selection of calibration method, the value of some common parameters must
be set.
All parameter values from the calibration should be noted in the set-up list, see
Appendix 1. These values are useful later, if the transmitter must be replaced.
Common parameters
These parameters define: the language, measurement unit and resolution used by
the transmitter, and also the capacity and signal type for the analogue output.
Set-up
1. Access ‘Quick set-up’
At normal operation WST 3 displays the actual weight value. Status for the internal
relays (R1/R2) in use and the transmitter Modbus address are also displayed.

2 seconds
This switches the transmitter into Set-up mode, displaying the main menu
for ‘Quick set-up’.
As WST 3 is in Set-up mode, normal measuring functions are interrupted!
