Measurements for which an additional charge will be made

  • Special construction required for contact
  • Measurement of particularly fragile modules
  • Samples with unstable electrical behavior
  • Samples with a high sensitivity to voltage reversal
  • Orders involving special construction for mounting or positioning samples
  • Required irradiance differs from STC
