Measuring:
When exceeding the maximum range limit (10kHz) independently from the limit setting an error
message will be displayed (“Err.1“).
6.5. Measuring of rotation speed (TTL, switching-contact)
This chapter describes how to configure the device for measuring rotation speed.
This instruction demands that you se

Switching contact, NPN
For direct connection of a passive switching contact (e.g. push
button, relay) or transmitter with NPN output.
There is a internal pull-up-resistor

Switching contact, PNP
For direct connection of a transmitter with PNP output.
There is a internal pull-down-resistor.

.
Decimal point:
Use the decimal point position to change the resolution of your measurement. The more the deci-
mal point position is on the left, the finer the resolution will become. Please note that you lower the
maximum value that can be displayed, either
Example:
50 rotations per minute.
without decimal point: display = 50, the maximum value 9999 rotations per minute.
decimal point on the left e.g. XX.XX: display = 50.00, maximum value 99.99 rotations per minute.
Connection:
For the connection of a frequency-transmitter, please follow the instructions given in chapter 5.3.6.
When connecting a switching-contact-transmitter with increased frequency range (= with external
circuitry) you have to select TTL as input signal.
