As and when this memory becomes full, the
´
FrEE
´ display will show 0.00; no further meas-
ured values will be saved. However, the in-
ternal memory can be configured as ring
memory. see Manual, 6.10.13.2

11.2.4 Cycle
To have measured values saved cyclically and
output via the interface a cycle must be spe-
cified. To specify a cycle select the cycle func-
tion ´
ZY
´ by pressing
FCT
(see 9.3)
If the cycle is 0, individual measuring opera-
tions will be recorded. Saving, i.e. recording
data to memory, is activated automatically.
Sleep mode
For long-term recording by cycles lasting longer than 1 minute the device can
also be operated in sleep mode. In energy-saving sleep mode the measuring
instrument is completely switched off after each measuring point scan (sensors
with their own power supply) and switched on again automatically after the
cycle expires ready for the next measuring point scan. In this way with just one
set of batteries or one battery recharge well over 50 000 measuring operations
can be performed; for a cycle lasting 10 minutes this represents an available
battery life of over a year.
To adapt the measuring function and the handling of limit value overshoot
events as closely as possible to the ambient conditions there are 5 sleep
modes with different displays and alarm messages. (see 11.1.3)
To select from among these 5 modes press
