Note: while in the talk mode other commands such as MONITOR, VERSION and SCAN
may be used.
Command:
DISPLAY COEFFICIENTS [DIS C]
This command, used in conjunction with the TALK command, will display the sensor’s
calibration coefficients. To exit the
talk mode
, use the CTRL C command.
Example:
>talk 203
(enter talk mode with the Sound Velocity board)
Entering talk mode
Sound Velocity Micro Sensor V1.40 SN:0002-SV
>dis c
(display the Sound Velocity sensor coefficients)
Sound Velocity
A=7.361894E-04 B=-7.438164E-056 C= 1.07834E-06 D=-5.791932E-07
Command:
CTRL-C
This command exits the talk mode.
(Press the ‘ctrl ‘ key and the ‘c’ key at the same time)
5.1.3.7 Editing the Calibration Coefficients
The instruments calibration coefficients are stored in the Micro SVT’s memory.
Accessing the coefficients for viewing or editing can be achieved by talking to the
individual sensor boards using the TALK command. The addresses of the sensor boards
are as follows,
Sensor board
Address
Pressure & Temperature
200
Sound Velocity
203
Analog
202
Once communications is established with the individual sensor board the user can view or
edit the calibration coefficients by using the DIS COEFFICIENTS or SET commands.
The following describes the method to edit the Calibration coefficients for each parameter
of the Micro SVT using the SET command. Refer to the TALK command for accessing
the coefficients.
Sound Velocity
Command:
SET n = c
Where n = the coefficient letter a,b,c,d,
c= calibration coefficient
