Execution Errors
If the identity is unknown an error is generated for the coefficient entry.
An error is generated if any of the coefficients exceed the limits for correct algorithm
operation.

Recalling the Characteristics of a Known PRT

PRT_DATA?
Recalls the characterization data and associated coefficients for the probe identity given.
Response Format:
This is a variable length response consisting of comma separated elements :
(string) Identity , algorithm , connection , (Nr3) R
coefficient2 , (Nr3) coefficient3 , (Nr3) coefficient4 , (Nr3) coefficient5
The 'Identity' consists of 17 ASCII characters enclosed with quotes.
The 'algorithm' will be one of the following: STD_PRT or CVD_ALPHA or
CVD_DIN or CVD.
The 'connection' will be one of the following: TWO_WR or THREE_WR or
FOUR_WR.
The first numeric value will be the resistance of the PRT at either the triple point of water
(STD_PRT) or zero degrees C (all CVD).
The number of coefficients appended to this response detailed above is dependant on the
algorithm used:

Deleting a Known PRT from the Non-volatile Store

PRT_DEL
Removes the probe from the store of probe data for the identity given.
4-20
PRT_DATA?
For CVD there will be no further coefficients.
For CVD_DIN and CVD_ALPHA there are three comma separated numbers.
For STD_PRT there are five comma separated numbers.
