Algorithm
Configuration
BPT algorithm: Write
the calibration data
for this user.Calibrate
the BPT algorithm
using the result of the
calibration
procedure. (Use the
data from the 0x51
0x04 0x03
command).

Algorithm
Configuration
BPT algorithm: Set
the estimation date,
using the current
date. The year is sent
as a 16-bit unsigned
integer, and the
month and day are
bytes.
0x50
0x04
0x04, year MSB, year LSB,
month, day

coefficients
A, B, C.
Defaults:
C = 0x42E16137
B = 0xC20AA37F
A =

0x50
0x04
0x0B, four bytes signed
integer A, four bytes signed
integer B, four bytes signed
integer C (32-bit integers
which are the coefficients
times 100,000)
The MAXREFDES220#
without the cover glass uses
the following coefficients as
the default values:
