5.1 Measuring speed and rpm
When using the device for measurement of revolutions per minu-
te, the time unit for F1 (tachometer 1) is set for r.p.m. in line 30, and
for F2 (tachometer 2) in line 31. The number of pulses per revolution
(scale) is specified in line 25 for F1, in line 26 for F2.
Decimal places
If you wish the display to include decimal places, this must be taken
into account when setting the measurement and decimal point as
follows:
1 Decimal place Scale x 0.1 Decimal 0.0
2 Decimal places Scale x 0.01 Decimal 0.00
3 Decimal places Scale x 0.001 Decimal 0.000

1 rev. = 1 pulse 1 none 9999 (U/min)
1 rev. = 1 pulse 0.1 0.0 999.9 (U/min)
1 rev. = 10 pulse 10 none 9999 (U/min)
1 rev. = 10 pulse 1 0.0 999.9 (U/min)
Speed measurement
When using the device for speed measurement for m/min., the time
unit for F1 and F2 is set in lines 30 and 31 (rpm), and the number of
pulses per metre (scale) for F1 is located in line 25, for F2 in line 26.
Formula for calculation of the scale factor: pulses/rev.
