3-8-10 Differentiation Function
The differentiation function is used to convert variations in measured val-
ues into output values. Use it for measurements that monitor changes in
measured values, such as counting the number of sheets.
When the Differentiation Mode is enabled, the number of cycles (measure-
ment period) to be compared can be set. (1 cycle: 150 µs)
Example: Measured Values and Differentiation Values
3-8-11 Display Reverse Function
The display direction of the digital displays can be selected. Select either
forward or backward according to the mounting direction of the Amplifier
Unit.
Refer to 4-5-11 Special FUN Mode Settings Related to Dis-
plays.
3-8-12 ECO Display Function
The ECO display function can be enabled or disabled. When the ECO dis-
play function is enabled, the digital display will not light.
The variation in the measured values indicates the difference
between the previous and current measured values. This value will
decrease when the number of samples to average is increased.
