Each digit indicates the following status :

D15 Start Word
D14 4
D13 When send the upper display data = 1

When send the lower display data = 2

D12, D11 Annunciator for Display

uS = 13 mS = 14 PPM = 19
% = 03

D10 Polarity

0 = Positive 1 = Negative

D9 Decimal Point(DP), position from right to the

left
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
