Conversion number is a coefficient of conversion between input values

and real full display range (10000 counts). See Table 3.2 below for proper

conversion number.

Table 3.2 Conversion Table

RANGE CONVERSION NUMBER

100 mV 10000 / (100 x 1) = 100

1 V 10000 / (1000 x 1) = 10

10 V 10000 / (1000 x 10) = 1

0 -20 mA 10000 / (20 x 1) = 500

Example =

0 - 1 V = 0 - 100.0

In 1 = 0

Rd 1 = 0

Inp 2 = 9999

Rd 2 = 100.0
