READ TEMPERATURE VOLTAGES (Command ‘n’)

Purpose: Returns the most recently acquired raw temperature data for the specified channels converted to engineering-unit Volts directly from the averaged A/D counts. It is similar to command ‘V,’ except that the raw data reflects a channel’s temperature signal instead of its pressure signals. Each datum returned in the response will be in the specified high-precision data format. This command is intended for advanced users only and is not required for normal operation.

Command

nppppf

 

n’ is the command letter

 

pppp’ is the position field

 

f’ is the format field

 

 

Response

dddd.. dddd

 

dddd’ are the datum fields, each with a leading space (except f= 7

 

or 8).

 

 

Description: The 4-character hex position field (pppp) specifies a 16-bit binary bit-map, with each bit (set to 1) specifying a particular channel number (16-1, left-to-right).

The 1-character format field (f) specifies the format of each datum field (dddd) that will be returned in the requested response. The first datum returned in the response will be for the highest channel number supplied, and each (non-binary) datum will be preceded by a space character. Some formats may not be applicable to the specific type of data being requested. Valid formats are shown in the following table:

f

converts each internal response datum value from . . .

max. char.
