Determine the correct values for Inputs ( " INPUt 0 " and " INPUt 1 " ). Calculate " INPUt 0 " and " INPUt 1 "
using the following equation:
"INPUt" = (Sensor Output) x (Conversion Number)
Conversion number is a coefficient of conversion between input values and real full display
range (100000 counts). See table below for proper conversion number.
INPUT RANGE CONVERSION NUMBER
0 – 100 mV 100000/(100 x 1)=1000cts/mV
0 - 1 V 100000/(1000 x 1)= 100cts/V
0 - 10 V 100000/(1000 x 10)= 10cts/V
0 – 20 mA 20000/ (20 x 1) = 1000cts/mA
Table 18-1. Conversion Number Table
Determine " INPUt 0 " and " INPUt 1 " Input range. For our transducer select 0 – 100 mV range.
" INPUt 0 " = 0 (mV) x 1000(cts/mV) = 000000
" INPUt 1 " = 30 (mV) x 1000(cts/mV) = 030000
1. Determine correct values for Display Reading ( " REAd 0 " and " REAd 1 " )
2. In most cases, " REAd 0 " and " REAd 1 " are equal to the minimum and the maximum of the
transducer output range.
"REAd 0" = 000000
"REAd 1" = 000100
