The LT51 will return 4 bytes (signed 32-bit value with MSB D3, LSB D0)
representing the data for:
READDATA1
– the
currently
selected terminals
READDATA2
– the AG terminals
READDATA3
– the BG terminals
depending on the following current measurement mode:

R & C
R = (D3 * 256) + D2
C = (D1 * 256) + D0 nF
If (R < 500)
R & C are in series
Else
R & C are in parallel
VOLTAGE
DCV = [((D1 * 256) + D0) / 100] V, NB: signed
ACV = [((D3 * 256) + D2) / 100] V
