You may enter information that will be written into the series of measurements generated
by the instrument. This can be a company name, as example.
Characters are entered in the same way like at a cellphone. For an „N“ press [ 6 ] twice, for
an „Y“ three times [ 9 ]. Pressing [Menu] alters between capital and small letters. Press [ C

7.2.5 Set
Minimum
Frequency
For the frequency input you may set the minimum frequency that shall be measured. All
smaller frequencies will be displayed as zero.
When using turbines for the measuring of volume fl ow rates, we recommend to set the
minimum frequency to „100 Hz“. When the system comes to idleness, the decay to zero will
be displayed with just a small time delay (10 ms). With a minimum frequency of 0.25 Hz,
„Zero“ would be displayed after four seconds.
For rotational speed measurements over 60 rpm with sensor and
one
refl ection mark we
recommend a minimum frequency set to 1 Hz. Then all rotational speeds between 0 and 59
rpm will be displayed as „Zero“.
For rotational speeds over 14 rpm you will have to set the minimum frequency to 0.25 Hz.
Then all rotational speeds between 0 and 14 rpm will be displayed as „Zero“. If rotational
speeds below 14 rpm shall be measured, you will have to use multiple refl ection marks.
The setting of the minimum frequency is a compromise between the required measuring
range and the desired dynamic in the detection of the measured value „Zero“.
