The calculation of the display-information influences the power
consumption significantly. When the application does not require a fast
display refresh rate, it is
strongly advised
to select a slow refresh rate.
Please understand that NO information will be lost; every pulse will be
counted and the output signals will be generated in the normal way.
The following refresh rates can be selected:
fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
(read 3 sec as a refreshment every 3 seconds, 30 sec as a refreshment
every 30 seconds)
When “off” is selected the display will be automatically switched off after
30 seconds since the last action. The display will return again after
touching one of the keys.
