Fig. 14: Display of the supply / evaluation unit (lamp test during switch-on)
The largest display value supported by the six-digit digital display is 999999.
The units for the measured value indicated appear on the right next to the digital display. The
default unit is kg/h. Other units are also supported.
"SENSOR 1" appears when transmitter 1 is selected.
"SENSOR 2" appears when transmitter 2 is selected (see section 5.5).
"TEMP 1" appears when the temperature of the fluid in transmitter 1 is requested.
"TEMP 2" appears when the temperature of the fluid in transmitter 2 is requested (see section
5.4).
"R.C. REMOTE-CTRL" appears when the device is in "Totalizer" mode (see section 6.1.2).

5.3.1 Adjustable
measuring
rate
It is often useful to produce an average from the configurable number of individual
measurements. You can set the required number of individual measurements using the selector
switch on the front of the supply / evaluation unit.
A measuring cycle period (time for an individual measurement) lasts approximately
3 milliseconds. The average value calculated for the number of individual measurements
configured is displayed and made available at the interfaces. In standard mode (i.e., when the
device is switched on/before the set measuring rate is adopted), the device automatically
generates an average value from 100 individual measurements.
If the device generates an average value from fewer than 100 individual measurements, the set
measuring rate is used for the analog outputs and the 12-bit parallel interface.
However, the digital display and the serial interface still contain measured values
reflecting an average value for 100 individual measurements.
Proceed as follows to set a measuring rate:
1.
Set the required measuring rate using the selector switch on the front of the
supply / evaluation unit.
2.
Press the "SAMPLE RATE" button to accept the set measuring rate. The selected measuring
rate appears briefly in the display field as an acknowledgment signal. The measured value
that appears after that is the first of the average values to be calculated from the newly
configured number N.
