Time interval in seconds
The measuring interval can be set between 1 and 9999 seconds. At the end of the
set interval the next measured value is stored in the memory automatically (max. 800
measured values).
Pressing the plus key increments the time interval, the minus key decrements it.
Keeping a key pressed automatically increments / decrements the time interval (auto-
increment). Time intervals > = 64 sec. enable the power save mode when a
measuring series is started in mode 3.

End,StP,memory loc. no.
Current temperature, HLt
If no interval measurement is active, the
small displays
shows ‘End’ and the
large
display
shows the current temperature value.
Pressing the plus key starts an automatic interval measuring mode provided an
interval timer > 0 has been entered in mode 2.
The
small display
always shows the current memory location number whereas the
large display
shows the temperature value for that location.
Pressing the minus key stops the interval measurement. In this case the
small display
shows ‘StP’. Pressing the plus key again continues the measurement in intervals. If
the measured value memory is full (800 values), the interval measurement stops
automatically. The active interval measurement also stops when the minus key is
pressed twice. The
small display
shows ´End´.
If a trigger function is active in mode 7 and an interval measurement is started, bars
are displayed in the top or bottom segment row (
small display
) as long as the trigger
temperature (mode 6) has not been reached. The actual interval measurement starts
only when the trigger temperature set in mode 6 is reached (actual temperature value
above or below the trigger).
If the mode is changed while an interval measurement is active, mode 4, mode 8,
mode 0 and mode 1 are not available. If the interval measurement is interrupted,
mode 8 and mode 0 are skipped. The min, max and mean value memories are
deleted after the interval measurement is started.
Power save mode:
If a time interval of > 64 seconds is set in mode 2, the measuring instrument changes
to power save mode after the measured value is stored. The
large display
shows
´HLt´. The measuring instrument is activated again just before the next measurement
and returns to power save mode again after the measurement
(power consumption in
power save mode is approximately 1mA)
.
The power save mode (´HLt´) can be exited by holding the minus key pressed. This
also automatically stops the interval measuring mode.
During long-term measurement the series can only be stopped (
small display
= ‘StP’)
at the time the measured value is saved in the memory.
