1.3 SETTING UP THE
TRANSMITTER
QUICK INSTRUCTIONS
CONFIGURATION AND CALIBRATION
When the transmitter is connected to the
process for the first time, it will operate with
default values set by the manufacturer. The
defaults are not sufficient, however. The
transmitter must first be configured and
calibrated in the actual process conditions.
The following is a description of the
simplest procedure (A) for a transmitter
where the sensor blade has been
mounted by the supplier (i.e., not a
standby transmitter installed to replace
e.g. a faulty transmitter).
This procedure enables an already
calibrated consistency measurement. The
other functions provide useful additional
features, but they are not necessary in basic
measurement.
The procedure is divided to three parts:
1. Defining the transmitter’s basic details,
i.e. configuration (A1 and A2).
2. Selecting the pulp types to be measured
(A3).
3. Adapting Valmet Automation’s laboratory-
defined calibration curves, optimised in
terms of pulp type and sensor blade, to the
actual process conditions (A6).
The appended Tables show the procedure
for setting up a transmitter which is taken
into operation for the first time. The Tables
show the required keystrokes and the cor-
responding displays. Steps A1 through A6
below describe the actions in more detail.
More detailed instructions for the menus are
found in the chapter Transmitter Functions
(Menus), which gives a detailed description
of the Calibration, Configuration,
Diagnostics and Measurement menus.
PROCEDURE
A1. Switch on the transmitter. Press [MODE]
and [
] to access the CONFIGURATION
menu. The text CONFIGUR is displayed.
Press [ENTER]. The text LOWER RA (=
lower range-value) is displayed. This is the
first parameter to be adjusted in the
configuration menu.
A2. You can select another parameter with
the arrow keys. Pressing [ENTER] will
display the selected parameter’s current

The operator unit consists of four pusbutton keys and an
8-character liquid crystal display. Press ENTER to
accept an option or command. Press MODE/ESC to go
to the next higher menu level or to the previous step,
depending on the command. Use the arrow keys to
view and/or select an option and to change numerical
values.
