3. Operation
In contrast to conventional hand-held measuring de-
vices this measuring device does not have a keypad
but what is known as a "THUMB-WHEEL" on the left-
hand side of the device.
The wheel can be turned up or down through 15° and
can also be pressed in the middle position.
Turning the wheel up selects the upper menu. Turning the wheel down
selects the lower menu for configuration and equalisation.
