5.2 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 a 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. For decimal places, see above.

5.3 Time measurements
When using the device as a time measurement system, the user
is offered the following functions, which can also be programmed
in line 21. The time range and resolution are defined in line 38. The
measurement result is displayed at F3.
After time-out, the display begins again at 00.00.00., whereby any
limit contacts which have been set are released again.
Path runthrough time Measurement of the runthrough time (e.g. of a conveyor belt)
required for a certain path (from A to B) taking into account the
speed factor. The measurement result is displayed at F3. The speed
can be picked up using an incremental pulse encoder with two signal
tracks „A 90° B“ on tachometer F1. In line 27, the required measure-
ment path must be programmed.
For this application, F1 is bypassed. On selection of this applica-
tion,„F1 OFF“ is displayed. F2 can be used to display rpm or speed.
