Example: To have an input of 4 to 20 mA displayed as 0 to 100,
The Low input value = min. input value * conversion number = 4(mA) x 500 = 2000
The High input value = max. input vlaue * conversion number = 20(mA) x 500 = 10000 (9999)
where: converison number is a coefficient of conversion between input values and real display range.
The full range of the display = 10000, conversion number = 10000/20 = 500.
