Temperature
P852 Temperature Source
This parameter determines the source of the temperature measurement. By
default it is set to External Range “A” (P852=4), which will use an external
temperature sensor with range -25˚C to 50˚C. If for any reason, no
temperature input is received, then the Fixed Temp value is used, as set by
P854.
The temperature source can be specifically set as follows:
Option
Description
1 = Automatic Will automatically select transducer
temperature sensor, if available, or fixed
temperature (P854) if no temperature
sensor found.
2 = Xducer Always uses temperature reading from
transducer.
3 = Fixed Always uses fixed temperature (P854)
4 = Ext Range “A”
(Default)
Uses an optional external temperature
sensor with an operating range of -25 o C to
50 o C.
5 = Ext Range “B” Uses an optional external temperature
sensor with an operating range of -25 o C to
125 o C.
P854 Fixed Temperature
This parameter sets the temperature, in degrees centigrade to be used if
P852 (Temperature Source) = 3. Default = 20 o C
