Program Group: 9
This program group defines the characteristics of the Analog sensors.
The DKG-705 unit has 4 analog sensor inputs. These are:
-Coolant temperature sensor input,
-Oil temperature sensor input
-Oil pressure sensor input,
-Fuel level sensor input.
The analog inputs are capable of measuring resistor values between 0 and 5000 ohms. Thanks to
the programmable characteristics, the DKG-705 may be adapted to any brand and type of sensor.
Each sensor’s characteristics are defined using a maximum of 8 known points. Each point consists
of a pair of value, the first being the resistor value and the second being the corresponding analog
measurement. For each sensor, 16 program parameters are reserved. Using defined points, the DKG-705
applies a linear approximation algorithm to find the analog value corresponding to an unknown resistor
value.
For a given sensor, the points must be entered in the increasing order of resistor
values, or faulty measurements may occur.
If less than 8 points are used, unused point resistor values must be entered as ‘0’.
