7. Operating elements of the calibrator/micro calibration bath
Cooling gradient SLoF
The cooling gradient, SLoF, is active if the reference temper-
ature is higher than the set temperature.
Only settings that are under the heating power of the calibra-
tor have an effect on the cooling gradient.

The dwell time, dur.t, is active when the set temperature,
SP1, has been reached. Subsequently, the calibrator or micro
calibration bath automatically switches to set temperature
SP2.
CAUTION!
If settings have been made for these three
parameters, the calibrator or the micro
calibration bath will not use the new values
until you either change the set temperature
or until the calibrator or the micro calibration
bath has been turned off and then on again.
Another approach would be to switch the
automatic control off before the parameter
change (see chapter 7.4.2 “Switching off
automatic control”), and then turning it
back on (see chapter 7.4.3 “Switching on
automatic control”).
The heating and cooling gradients and the dwell time can be
set via the parameter level, ’rEG. This is achieved by press-
ing button P for approx. 5 secs., this opens the main menu.
The upper PV display will show OPEr.
In the lower SV display, the LED SET will blink.
If button P is pressed again, this opens the groups level.
The upper PV display will show OPEr.
In the lower SV display, ’SP is shown and additionally LED
SET will blink.
Select the group, rEG, by pressing button 6.
The upper PV display will show OPEr.
In the lower SV display, ’rEGis shown and additionally LED
SET will blink.
