Data Memory for measured values
11.2.3 Numbering of measurements
For the identification of measurements or series of measurements it is possible
to individually enter a number before starting. With the next measuring point
scan it will be output or stored, respectively. This allows to also assign single
measurements during a read-out to specific measurement locations or mea-
suring points (s. manual 6.7).
After selecting the function
Number
the 6-digit number is entered in the usual
way (s. 9.5). In addition to the figures 0 to 9 the characters A,F,N,P,- or _
(space) can be used. After the input the number is activated and next to it an
´
A
´ will be indicated until the next cyclic or manual measurement will be stored.

11.2.4 Starting and Stopping of measurements
Additionally to starting and stopping of the
measurement with the keys, there are even
more possibilities, concretely conveyed by the
assistant menu
START-STOP
.
The operation via interface is described in the
manual section 6.6.
The function of start time and end time or
measuring duration is described here in sec-
tion 11.1.4, the limit value responses in sec-
tion 11.4.3 and the varieties of relais and
trigger in section 11.6.2.
11.2.5 Scanning mode
For autonomous operation and / or for scan-
ning by computer there are 4 scanning modes available.
Normal
Internal cycle or cyclic scanning by the computer
Sleep
Internal cycle only, automatically switching off for long-term monitoring
Monitor
Internal cycle, not disturbed by computer scanning
Fail-safe
Cyclic scanning by the PC after any failure the internal cycle
Sleepmodus:
For long term monitoring with larger cycles it is possible to operate the measur-
ing device in sleep mode. Within this power saving mode the device will be
switched off after each measuring point scan (this is to be considered using
sensors with power supply!) and will be automatically switched on for the next
measuring point scan after the cycle time has expired. This procedure allows,
with one set of battery/accumulators to perform more than 15000 measuring
