Speed measurment
When using the TA 201 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:

Measurement functions

The measurement functions are described below. These functions
are selected in line 21. For monitoring two speeds or rpm values or
of one speed and one rpm value which you wish to display in the
form of ratio, differential or extension / compression value (discre-
pancy in percentage terms). In the event of a percentage display the
scale is set with the factor 100.
