CAN-2084C

User’s Manual (Version 1.00, Sep/2018) ------------- 17

2.8.3

Mode 2: Frequency Mode

We calculate frequency of a certain channel by how many counts in a period of time.

There are two modes: Normal Mode and High Speed Mode for measurement

frequency

Normal Mode:

Normal Mode will read 1 pulse, this pulse will be calculated frequency value.

High Speed Mode:

High Speed Mode will read 11 pulses to calculate average value of those 11

pluses.

High Speed Mode will be more accuracy than Normal mode for measurement

Frequency. We suggest using High Speed Mode if measurement frequency is more

than 10k Hz.
