Data entry into the register is confirmed by a short illu-
mination of the Status lED in red.
Before the required number of correct measurements
(according to Table 1) is achieved, the device displays arithme-
tic mean from the completed measurements. Subsequent me-
asurements are added applying the walking window principle,
i.e. the “oldest” measurement is deleted and replaced
by the most recent one. When values outside the measuring ran-
ge are measured, the device indicates it and correct measure-
ments are counted from the beginning. Default time is set to 1s.
