Since the refractive index is highly depending on the temperature the temperature of the
optical bench of the RI2012 refractive index detector can be controlled by the micro
controller. To set the desired temperature press the
MENU
button until the following status
line is displayed.
Currently the temperature control is switched OFF. The optical bench is operated at ambient
temperature plus additional 7 °C caused by internal heating resulting from different
electronic components which heat up when operated. As a result of this the temperature
can be controlled in a range from 35 °C up to 55 °C only. To change the temperature
setpoint press the
ArrowUp
(
▲
) to switch to higher temperatures or use the
ArrowDown
button (
▼
) to select a lower temperature. If you set the temperature control to OFF the
optical bench is operated at ambient temperature plus 7 °C.
Pressing the
ENTER
button accepts the new setting. In the normal measuring mode an
asterisk (*) in the left top corner of the display indicates the activity of temperature control.
The temperature sensor is constantly controlled by the internal firmware of the instrument. It
is not possible to activate the heating when one of the following reasons occurs:
The temperature sensor does not work or is not connected. In this case the error
message “noTS” will appear in the display.
