Reading Configuration (If Process was selected) INPUT/READING (SCALE AND OFFSET) SUBMENU: Input Voltage or Current can be converted or scaled into values appropriate for the process or signal being measured. So, a reading may be displayed, for example, in units of weight or velocity instead of in amperes or volts. The instrument determines Scale and Offset values based on two user-provided input values entered with the corresponding readings.
Conversion number is a coefficient of conversion between input values and real full display range (10000 counts, shown as 9999). See Table 3.2 below for proper conversion number.
