232_TRI-SEN – Functions
9.4 Resetting the temperature measurement
When the °C key and the On/Off key are simultaneously pushed
for at least 1 second, the temperature measurement can be set
back. There will be an extended signal tone, and temperature val-
ues (count and mean value) are set to 0.
With this function, the temperature measurement can be reset
without completely switching off the TRI-SEN.
9.5 Measuring the irradiation
Once the TRI-SEN is switched on, the integrated solar cells meas-
ure the irradiation. After the temperature measurement, the
TRI-SEN is placed in the mounting which is fitted flush with the
modules (chapter 4.5). The position of the TRI-SEN at module lev-
el is crucial for the accuracy and reliability of the STC evaluation!
The irradiation is measured continuously, stored at intervals in the
memory and transferred to the TRI-KA. The current irradiation is
shown in the top left-hand corner of the screen.
9.6 Measuring the angle of inclination
Once switched on, the TRI-SEN continuously measures the angle
of inclination, shown in the top right-hand corner of the screen.
For a reliable measuring result, the TRI-SEN should be placed in
the mounting fitted to the module frame (chapter 4.5).
