    Solar Cell I-V Test System (Manual) User Manual 10. Test Device The system is shipped with a test device with 100 kΩ resistors that can be used to check the calibration of the system. They are arranged in the geometry of the substrate pixels, and the appearance of the test device will depend on the substrate system being used (Figure 10.1).
  • Page 26 Solar Cell I-V Test System (Manual) User Manual Resistance can be calculated using: R = V / I II. For the 200 mA current range the calculated resistance should be between 98 and 102 kΩ (within 2% of the resistor value).
