4.6 switching on the instruments
The instruments are switched on using the On/Off button. Once
switched on, the display is activated. The TRI-SEN signals readiness
for operation with a short beep.
Before the instruments are switched on, make sure that the
battery has been charged (chapter 4.2). For the TRI-KA it is also
important to remember that the SD memory card must first be
inserted. The SD card stores the measured data. The customer and
module database is also kept on the SD card.
The instruments are switched off again by pressing the On/Off
button. The display goes out once the instruments are switched
off.
5. TAKing A MeAsUReMenT
The steps
Measuring the module temperature at several points of the string
or module to be measured (chapter 9.3). It is recommended to
measure the temperature at least 3 times before measuring the
characteristic curve and at least 3 times after.
Fitting the TRI-SEN mounting to the module/string to be meas -
ured and measuring the irradiation (chapter 9.5).
Using the TRI-KA to measure the open-circuit voltage (U
OC
) and
the short-circuit current (I
SC
) and determine the system’s current/
voltage characteristic curve (chapter 7.1).
Wireless transfer of the measured data from the TRI-SEN to the
TRI-KA during or after measurement (chapter 10.1).
Importing the measured results via SD card from the TRI-KA into
the PC and evaluating them using the software provided (chapter
10.2).
