Parameters (soft key):
Displays the CHANGE PARAMETERS menu (Figure 2.81) which contains:
CONC (RI) (soft key):
Further by the soft key "Parameters", the calibration parameters for the concentration are entered, see
Section 5.2.
Menu selected functions are:
1. Concentration unit, can be "CONC %", "CONC g/l", "CONC", “OECHSLE” or "BRIX". Also
available is the unit RI (x °C), which is "RI measured in the laboratory at x °C" where typically
x = 60 °C, displayed as RI (60 °C). The unit RI (x °C) should not be confused with "Standard
RI (25 °C)" even if the x can be chosen as 25.
2. Number of CONC display decimals.
3. Damping time in seconds. This is the time it takes for the concentration measurement to reach
half of its final value at a step change of the concentration
4. Switch selected scales. Provides four additional complete sets of calibration parameters, see
"Switch inputs" below.
1. Prism wash:
Entering of prism wash times for the Relay Unit and a wash check, wash stop and smart wash functions, see
Section 9.2.
2. Relays:
Provides relay configuration, see Sections 2.5 and 9.2.
3. Switch inputs:
The microprocessor accepts four switch inputs (A, B, C and D), for connections see Figure 3.63. The
function of each switch can be individually defined from one of four alternatives
0. Not defined (which is the factory setting).
1. Remote wash start for Relay Unit wash function and external Hold. The external Hold is used
with a wash timer other than the Relay Unit, or to hold the signal during stops in an intermittent
flow (e.g. by contact from the pump control). A wash start is also initiated when the contact
opens, if it has been closed longer than one minute.
2. Defined to select alternative process mediums. There are all together four alternative mediums
selectable by closure of the corresponding switch. If no selection switch is closed, the normal
medium is selected. Maximum number of mediums is five (Normal, A, B, C, D).
Note. The range will not change. Example: medium 1 = 20 - 40 % Sugar, medium 2 = 20 - 40
% Salt.
3. External wash stop: An input switch can be configurated to an external wash stop to prevent the
prism wash when the corresponding input switch is connected. “External wash stop”-message
will show when automatic wash is activated. The input switch can be set to protect the
refractometer e.g. if the process is stopped.
4. Calibration stop: An input switch can be configurated for calibration stop. Activating and
connecting the input switch will prevent calibration through software.
