Input of the dwell time
Press button P.
On the upper PV display, dur.t will blink.
On the lower SV display, the corresponding currently-select-
ed dwell time is displayed.
By pressing button P, the newly-set dwell time, dur.t, is
accepted.
The screen returns to the parameter level.
CAUTION!
If no button has been pressed for approx.
15 secs., an automatic return to one level
above in Calibration mode occurs.
After the setting has been made, the calibra-
tor or the micro calibration bath will not use
the new values until you either change the
set temperature or the calibrator or the micro
calibration bath has been turned off and
then on again.
8. Cooling down the metal blocks or micro calibration baths
WARNING! Risk of burns!
Before transporting or touching the metal
block or micro calibration bath, make sure
that it has cooled down sufficiently, as there
is an acute risk of burns from both the metal
block and micro calibration bath and also
from the test item.
In order that the calibrator or the micro
calibration bath can be brought quickly from
a higher to a lower temperature, set the set
temperature to a lower temperature (e.g.
room temperature).
With a heating instrument, the built-in ventilator will automati-
cally slowly switch to higher speed, which will provide a
cooling airflow.
The LED OUT 2 signals the status of the outputs for the
fan control. If LED OUT 2 is on, the fan is running at higher
speed, if LED OUT 2 is not on, the fan is running at lower
speed.
With a heating and cooling instrument, the controller will
switch the active cooling on. The LED OUT 2 signals the
status of the outputs for the fan control. If LED OUT 2 is on,
the active cooling is running, if LED OUT 2 is not on, the
cooling is not active.
WARNING!
After switching off or removing the mains
connection, no cooling air will be provided
by the built-in fan. A sufficient thermal
decoupling between the metal block and
liquid bath and body is nevertheless guaran-
teed.
By pressing button 5, the dwell time, dur.t,is increased.
By pressing button 6, the dwell time, dur.t,is decreased.
By pressing button 5 or 6 the value is
increased or decreased by 0.1. If the keys
are held down for at least 1 sec., however,
the value increases or decreases more
rapidly, and after 2 secs. even faster, so
that the desired value can be reached very
quickly.
