Hardware Information
(Changes reserved)
Build in a stable and water proof (IP67) plastic case with carrying handle, automatic pressure valve and tough
front panel.
12.1 Measuring Unit
Sampling rate max. 100kHz
Resolution 0.01V - 0.25V, 0.0005A – 0.005A (depending on sel. range)
Accuracy of the a/d converter 0.08% of FSR±1 LSB
Peak power measurement: ±5%
Reproducement: ±2%
Duration of single measurement: 20ms up to 2 seconds, avoiding the influence of capacitive properties of the
module under test.
Irradiance reference sensor (Phox) with integrated Pt100 or Pt1000 temperature sensor measures irradiance
and cell temperature. Other commercially available sensors as e.g. ISET-Sensor® can be connected using a
reliable cable connection.
Pinout of sensor plugs:
10.2 Pin allocation of the sensor connections:
Temperature (external): 4 pin female chassis socket Lumberg KFV40
Pin 1 = Current (~1 mA)
Pin 2 = Pt100 +
Pin 3 = Pt100 -
Pin 4 = Current source - (~1 mA)
Irradiance: 8 pin female chassis socket Lumberg KFV81 (plug: SV81)
Pin 1 = Irr
Pin 2 = Pt1000 (reference) +
Pin 3 = Irradiance-
Pin 4 = Current (~1 mA)
Pin 5 = Current source - (~1 mA)
Pin 6 = do not connect
Pin 7 = do not connect
Pin 8 = Pt1000 (reference) -
