Speed adjustment coefficient
Speed measurement value may have some errors with the actual speed value, by setting speed
adjustment parameter can correct the errors.

Filter coefficient
If there are large fluctuations measured values by various causes in the measurement process, set the filter coefficient appropriately can make it stable.

Threshold voltage
In some applications, the duty cycle of the signal that picked up by speed sensor is very small or very
large, and there is big shaft vibration on the shaft, then adjust the parameter can obtain the best
threshold voltage.

Limiting threshold voltage
Limiting threshold voltage can improve the anti-interference ability of speed measurement. When the
limiting threshold voltage is larger, the anti-interference ability is better. But the limiting threshold voltage
is restricted by speed signal, when the speed signal has a large range, you can set a larger limiting
threshold voltage.

Alarm delay time
Alarm delay in unit of second, in 0 ~ 10 seconds can be set.
