Cooper Instruments & Systems DFI INFINITY B Ultra High Performance Digital Force Indicator - Manual (Page 54)

To scale "MANUAL", calculate inputs based on transducer specifications and manually enter them via on the front panel
push buttons. The following example assumes load cells with this specification:
Maximum Load:....................................................................100.0 lb
Output ................................................................................3.0 mV/V
Sensor Excitation ......................................................................10 V
Maximum Sensor Output = 3.0(mV/V) x 10(V) = 30mV
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
0 - 1 V
0 - 10 V
0
– 20 mA
100000/(100 x 1)=1000cts/mV
100000/(1000 x 1)= 100cts/V
00000/(1000 x 10)= 10cts/V
20000/ (20 x 1) = 1000cts/mA
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
