10. MEASURING OPERATIONS

With the ALMEMO
scanned continuously; this permits continuous differential measurements and
ensures continuous temperature compensation for dynamic pressure probes
or chemical probes. (see Manual, 6.5.1.3) Up to 12 measuring channels can be
displayed. see 8.2 A measured value can be sent to an analog output.
see 12,2 and Manual, 5.1.1

10.1 Battery voltage

As soon as the device is switched on, a seg-
ment test is performed; then the battery sym-
bol appears and the available battery
voltage ´Ubat´ is displayed. The battery sym-
bol is an outline containing 3 sections; these
indicate the battery status. If the battery is al-
most empty, the last of these sections will
briefly appear in red; then the battery symbol
outline will flash (<3.3 V). Now - at the very
latest - the rechargeable batteries must be recharged. (see 7.1)

10.2 Measured value

The measured value and its appropriate units
are displayed in the main field and the meas-
uring point is displayed in the function field.
All special operating states affecting a meas-
ured value are explained in 9.1;
the special ways of indicating that a limit
value has been exceeded are explained in
11.1.3.

10.2.1 Selecting a measuring point

To select one after the other all active measuring points and have the current
measured value displayed for each of these press
ous channel press
To increment the measuring channel
To decrement the measuring channel
The measuring range abbreviation appears briefly in the display. see 10.2.2.
