OPERATION
TRANSCEIVER
The IQ Radar 160 transceiver operates under 1 of 5 sets of preset conditions
(P003), summarized as follows:
parameter
value
measurement
response
echo
verification
filter fail-safe
timer
1 0.1 m/min slow on on 100
2 1 m/min • on on 10
3 10 m/min • on on 1
4 100 m/min • off on 0.1
5 1000 m/min fast off off 0
When the echoes are received, the relevant echo extraction technique (P820) is
applied to determine the true material echo.
The measurement response limits the maximum rate at which the display and
analog output respond to changes in measurement. It is of concern especially
where liquid surfaces are in agitation or falls into the radar path during filling.
