Measuring - VOLTCRAFT TC-150 Manuel D'utilisation

If the temperature is increased, the heating process is signalled by the function display "OUT" (1).
If the temperature is reduced, the function display "OUT" goes out or fl ashes.
If the actual temperature value (display 3) is >4 °C over the target temperature value (display 2), the
two red function displays "ALM1" and "ALM2" are activated. These displays signal a larger temperature
deviation at the moment. When the temperature difference of >4°C is undercut, this display goes out.
ALM1 : Heating has been interrupted briefl y
ALM2 : Cooling is increased.
The physically generated temperature (heating
element) has a low difference between actual
and target temperature. The table shows the
deviation between reference temperature and
actually pending temperature.
Outer infl uences like drafts may increase this
difference.

MEASURING

Temperature sensors have different shaft diameters. To be able to use as many different sensor types
and diameters as possible, different bores are placed in the calibration body.
Unfortunately, not all dimensions can be considered. Therefore choose the bore that matches your
sensor diameter best.
Push the sensor shaft straight into the matching opening (4/5), until the sensor has contact.
Since air is a bad heat conductor, it can be benefi cial to use heat conductor paste during
calibration. This paste serves as a heat bridge between the calibration body and the
temperature sensor. Measuring deviations are reduced by this. After use, clean the cooled
measuring openings of the heat conductive paste thoroughly with a cotton swab or similar.
The top of the housing also has an opening (4) for penetration thermal sensors with a shaft diameter of
max. 3 mm. This opening can be used for calibration, like the front bores, or to monitor the temperature
of the calibration body with an external thermometer.
After measurement has been completed, the temperature must be adjusted to
<60 °C. Do not switch off the device if the display shows a temperature of >60 °C.
The accumulated temperature could destroy the device. Never operate the device
unattended.
