all available functions and change the value of all available parameters.
The instrument is equipped with the super contrast OLED colour display (96 x 96 pixels), which displays
the measurement results and the configuration menu.
The instrument has two general modes of operation: measurement performance / results preview mode
and configuration mode with the use of menu functionality.
