During the program run, you can toggle between the main menu
and the data logging menu to display temperature levels already
processed.
Once the program run of the logging program has been completed,
the ramp program and the data logger are automatically set to OFF.
The calibration data recorded can either be displayed in the data
logging menu or downloaded via the RS 232 interface.
This menu is used for configuring the temperature switch test. It is
possible to determine switch points and the hysteresis of a
temperature switch.
The switch test program and
the temperature ramp program
are automatic program runs
that exclude one another. When
the program is enabled, all the
functions not used for testing
temperature switches are
disabled.
The switch test is started by pressing ENTER and can be aborted at
any time with CONTROL ON/OFF. An interrupted switch test is
identified with the status bar message SWITCH TEST. HEAT UP or
COOL DOWN will be displayed in the status bar during the switch
test.
Rem. temp, T
max
or T
min
are displayed to the left-hand side of the set
temperature. After the test has been completed and the hysteresis
has been calculated, the removal temperature will be controlled
such that a new switch test can be started. If the temperature
fluctuations are < 0.1 K, TEMP.STABLE will be displayed in the
status bar.
