Regulation of the temperature of the medium
using PT1000 double temperature sensor
Operation with the PT1000 double
sensor is indicated on the digital
display by the
symbol. One
temperature sensor is located in the
heat carrier fluid and the other is
located in the reaction medium. The
set target temperature (2) refers to
the temperature of the medium. The
higher temperature is automatically
attributed to the heat carrier fluid and
shown on the display as an additional
current temperature with the symbol
(3).
The actual temperature of the reaction
medium is shown as the current
temperature (5). The heating plate
temperature (and therefore the heat
carrier fluid temperature) are limited by the set heating plate
safety temperature limit (7). The reaction medium temperature
is limited by the set temperature limits (carrier fluid/reaction
temperature limit).
see section entitled "Limits"
Limits
In order to ensure that neither the reaction fluid nor the carrier
fluid overheat, the user can set separate temperature limits.
• S croll to the "Heating" icon
in the menu
• O pen the submenu by
pressing the rotary knob (D)
• O pen the "Limits" submenu
followed by "Medium
limit" and then set the
temperature limit for the
reaction fluid.
• C onfirm the set limit by
pressing the rotary knob (D)
• O pen the "Carrier limit"
submenu and set the limit
temperature for the carrier
fluid.
• C onfirm the set limit by
pressing the rotary knob (D)
• O pen the "Limit
information" submenu.
All set limit temperatures,
including the safety limit
temperature of the heating
plate, as displayed on one
screen.
• C lose the submenu by
pressing the rotary knob (D)
Calibrating the temperature sensor
In order to use tolerances to limit temperature deviations, the
user can calibrate the temperature sensor in conjunction with the
device.
2-point calibration:
Calibration using two temperatures
3-point calibration:
Most accurate way of calibrating the temperature sensor at three
different temperatures
Note:
A calibration carried out by the user is indicated on the display
with the symbol (11) shown in red.The calibration of the PT100
and PT1000.50 double
sensor are carried out
separately.
• S croll to the "Heating" icon
in the menu
• O pen the submenu by
pressing the rotary knob (D)
• O pen the "Temperature
sensor" submenu and
then "Calibration", finally
confirming by pressing the
rotary knob (D)
• S elect either 2-point
calibration or 3-point
calibration and confirm by
pressing the rotary knob (D)
In this function, the speed can be pre-set before starting the
calibration.
