What is the prescale function?
The prescale function converts the count into an actual
value (amount) and displays it.
Example
For a device that outputs 500 pulses when 1 m has been fed:
1. Set decimal position to the last 3rd place.
2. Set the prescale value to 0.002 (1/500).

• Leakage current: 1.5 mA max.
• Breaker capacitance: 5 mA min.
• Residual voltage: 2.0 V max.
• Usable voltage: Runs on 10 VDC
* If a dual-line sensor is connected to a 12 - 24 VDC/24 VAC type,
24 VDC (21.6 to 26.4 VDC) and 24 VAC (21.6 to 26.4 VAC)
should be applied to the power supply voltage of the counter.
