EXAMPLE 2

To show the rpms of a wheel with 250 pulses/rev, with max. frequency less than 1 kHz, set
FP = 0, P.S = 8 (full scale 1 KHz), M

U

= 6, d

E

= 25

EXAMPLE 3

For applications requiring greater precision of frequency value (with max. full scale 500 Hz), you can set a sampling time
greater than one second.
To show the frequency in pulses/second with fixed scale, with one decimal figure and with sampling time at a constant 5 sec,
set FP=3, tc =5.0 sec, P.S = 8 (full scale 1 KHz), M

EXAMPLE 4

Calculation of frequency displayed (F.v.) with a proximity input
With a full scale of 20KHz, the assigned prescaler ratio is 4; therefore the value shown is:
