Temperature presentation
On the PI32 display, the temperature is displayed in the numeric
display. If the temperature is falling or rising, this is shown with
an arrow. When the readings are stable, the digits are shown in
black colour. When the values are predicted, the digits are grey,
and if the contact with the sensor is lost, the characters *.* * are
shown in grey.
(A) = Sensor set up as sensor no.2.
(B) = Current temperature.
(C) = Denomination (Celcius or
Fahrenheit)
(D) = Temperature change. This
arrow indicates that the temperature
is rising.
(E) = Graphic alarm
(F) = Indicator, lit for every sensor interrogation.
(G) = Interference symbol.
Sensor configuration
On delivery, all temperature sensors are configured in Channel 8
and with Fast update rate. If you use more than one sensor, you
must set them up to operate in different channels.
Note:
The sensor and the PI32 system setup must correspond,
otherwise the communication will not work.
To change the sensor setup (channel selection), use the PI
Configurator utility.
The sensor update rate controls how often the sensor reads and
reports the temperature. Three settings are available. Note that a
faster update rate will decrease the battery life.
•
Fast (~4,5 sec): Recommended for purse seine or trawl,
allows immediate update of changes in the sea temperature.
•
Normal (~14 sec): Recommended for trawl and normal
fishing with fairly constant sea temperatures.
•
Slow (~34 sec): Recommended if you experience constant
sea temperatures, or if maximum operational battery life
before charging is required. The system will be more
sensitive to bad communication conditions due to the slow
data update.
