10.2.2 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 measu-
ring points (s. manual 6.7).
After selecting the function
Number
the 6-digit number is entered in the usual
way (s. 8.5). 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.

10.2.3 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 is de-
scribed here in section 10.1.4, the limit value
responses in section 10.4.3 and the varieties
of relais and trigger in section 10.6.2.
10.2.4 Sleepmodus
For long term monitoring with larger cycles it is possible to operate the measu-
ring 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
point scans. At 10 minutes for one cycle this results in a total measuring time
of more than 100 days.
The following steps must be carried out in the menu
Recording to memory
to
perform a
data recording in the sleep mode
:
1. Enter a cycle with a min. duration of 2 minutes:
Cycle: 00:05:00
2. Switch on the storage activation in the cycle:

Sleep: -
3. Select the sleep mode:
