Taking a closer look at Nor150
Placing the finger for a few seconds in a graphical
display or numerical table or pushing the
√ button
gives access to a context sensitive menu with various
selections available for the current display – easy and
intuitive.
The backlight brightness is preset from the factory to
work in various environments. It is however possible to
adjust it in the power setting menu to optimise it for the
current light condition. It may be needed to increase the
brightness in heavy sunlight, while dark environments
may call for a lower setting. Additionally there is a time
out function that will turn off the backlight after a preset
time. Touch the screen or push a button and the light
will be turned on again.
Please note that the use of the backlight makes a
significant impact on the power consumption.
Use the measurement control (
Start/Stop
,
Pause/
Continue
) in the touch sensitive display when you
measure low noise levels. The touch sensitive
display is completely noiseless compare to a
traditional keyboard.
