10. MEASURING OPERATIONS
With the ALMEMO
®
2470 all available measuring channels are by default
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.
