Calculating the maximum absolute error of the counter module 1Count24V/100kHz (6ES7 138-4DA02-0AB0) when measuring rotational speed

Part number:

QUESTION:
How can you calculate the maximum absolute error of the counter module 1Count24V/100kHz (6ES7 138-4DA02-0AB0) when measuring rotational speed?

ANSWER:
If the information in the manual about the error when measuring rotational speed is not sufficient for your purposes, you can use the following formula to calculate the maximum absolute error:
