For sensors that output more than one data value, only the first value will be

shown in response to Rx,y command.

Sx,y Display SCALED sensor data for sensor numbers x through y. Your terminal emulation program

will display scaled data from each sensor updated once a second.

All measurements made by multi-output sensors will be shown with the

Sx,y command.

7.2. SCALING (CALIBRATING) RAW SENSOR DATA

Scaling (or calibrating) of the raw sensor data is defined by the three line items 13, 14 and 15 in a Sensor

Record.

160

These three line items define three coefficients (A, B, and C respectively) for the following

quadratic equation:

"y" represents the scaled (or calibrated) value and "x" represents the raw sensor value.

Option Cx (Calibrate Sensor Record x) in the Test Menu allows you to modify the settings of A, B and C

for Sensor Record Number x.

As an example, you have 10 Sensor Records defined in your sensor suite, and Sensor Record #3 is a 12-

bit ADC Sensor reading wind direction. If you need to recalibrate the conversion of volts to wind

direction of Sensor Record #3, you would type C3{ENTER} in the Test Menu. You will then be shown

the user-defined name for the Sensor Record and be prompted with three questions to set three new values

for coefficients A, B and C.

If you hit {ENTER} without entering a new coefficient value, the old value

will remain unchanged.

Your screen will look something like this:
