value in a 1-byte (8-bit) format. The calibration temperature is an integer value.

 

 

 

 

Example

The following example translates the OUT_BYTE returned value into a decimal

 

 

integer calibration temperature value (°C):

 

 

1.

°

Convert to calibration temperature.

 

 

 

19h = 25 C

Command Name

Query Calibration Date

 

 

 

 

 

 

 

Command Format

8Bh

 

 

 

 

 

 

Description

The Query Calibration Date command returns the calibration date in a 3-byte (24-bit)

 

 

format.

 

 

 

 

 

 

Example

The following example translates the 3-byte (HIGH_BYTE-MID_BYTE-

 

 

LOW_BYTE) output to a calibration date:

 

 

1.

05h = 5

Convert the HIGH_BYTE to get the month.

 

 

2.

1Ah = 26

Convert the MID_BYTE to get the day.

 

 

3.

63h = 98

Convert the LOW_BYTE and add 1900 to get

 

 

 

98 + 1900 = 1998

the year.

 

 

4.

5-26-1998

Forms the calibration date of May 26, 1998.
