On the ALMEMO ® 2450-1 all measuring channels, whenever available, are
scanned semi-continuously at 2.5 mops; (see Manual 6.5).
Up to 4 measuring points can be displayed; (see Section 8.2)
A measured value can be sent to an analog output; (see 12.2, Manual Section
5.1.1).

After switching ON first of all a segment test
is performed; then the battery voltage ap-
pears and if the batteries are almost empty
(<3.8 V) the

measuring point is displayed in the function
