RemoDAQ-8031A/33A/34 User’s Manual 

3.4 $AA0 

Name

：

Span Calibration 

Description

：

Calibrates module to correct for gain errors. 

Syntax

：

$AA0 (cr) 

$  delimiter character. 
AA address of the module that is to be calibrated(00~FF) 
0  span calibration command. 
(cr) the terminating character, carriage return (0Dh). 

Response

：

!AA(cr)    if the command was valid. 
?AA(cr)    if an invalid operation was entered. 

Syntax error or communication error may get no response. 

!  command is valid. 
?  command is invalid.

 

AA    address of the module (00~FF)   

In order to successfully calibrate an analog input module’s 

input range, a proper calibration input signal should be 
connected to the analog input module before and during the 
calibration. 

Example

：

 

Command

：

$010     Response

：

!01 

Span calibration of address 01,return success 

Command

：

$020     Response

：

?02 

Span calibration of address 02,return the calibration is not 

enable before span calibration command   

 

Notice

：

Command only for
