Analogue
Pr.30 Analogue Output (Common to all points) (D=1)
The analogue output will be related to span (Pr.5). On single point applications see
also Pr.32 and Pr.33
Enter 1 - 4-20mA
2 - 20-4mA
3 - 0-20mA
4 - 20-0mA
5 - 4-20mA ) > will over-range 0-24mA if normal span
6 - 0-20mA ) (Pr.5) is exceeded
NOTE: Refer to Pr.34 for output test.
Pr.32 Analogue Datum (Used only on single point systems) (D=0.00)
If an analogue output is required with a zero different from the measurement zero
(Pr.4) then an offset defined as a percentage of the measurement span/volume etc., can
be entered here.
Pr.33 Analogue Span (Top level) (Used only on single point systems) (D=100)
If an analogue output is required with a span different to that defined for the
measurement (Pr.5) then an alternative value for the top limit of span, defined as a
percentage of the measurement span/volume etc., can be entered here.
Pr.34 Analogue Output Test (Applies to the point selected) (D=0.00)
This parameter can be used to examine the last analogue output value set up by the
instrument. Also any value in the analogue output range can be entered for loading to
the current output, and can be measured at the output terminals, to test the external
analogue circuitry.
Temperature Compensation
Pr.37 Temperature Sensor Enable (Define for each point) (D=1)
1 = No sensor attached
2 = Sensor attached
Pr.38 Compensating Temperature (Define for each point) (D=20°C)
If no sensor is fitted the vessel temperature may be entered here.
Pr.39 Temperature Sensor Test (Applies to the point selected) (D=0.00)
Displays the sensor resistance in K Ohms. Typically 9.5 at 20°C.
If value shows '0.00' after switching 'Off' and 'On' then either no sensor is connected,
or there is a short circuit or open circuit in the system.
