Prescaling
The prescale function makes it possible to convert the counting value of the
K3NC into an appropriate value.
For example, the system shown in the illustration outputs 250 pulses when
the object is advanced 0.5 m. To enable the K3NC to display @@@@.@ (mm),
obtain the advanced length of the object per pulse from the following formula.
500 mm (0.5 m)/250 = 2
1. The prescale value is set by the mantissa X multiplied by the exponent Y
as follows:
Prescale value = 2.0000 x 10⁰
X = 2.0000, Y = 00
2. Set the decimal point to the left of the rightmost digit.
