Build in a stable metal case with carrying handle and tough front panel.
13.1
Measuring Unit:
Sampling rate max. 100kHz
Resolution 0.01V - 0.25V, 0.005A – 0.01A (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
Phox sensor with integrated Pt1000 sensor measures irradiance and cell temperature. Other commercially
available sensors as e.g. ISET-Sensor® can be connected using a reliable cable connection.
13.2
Pinout of sensor sockets:
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) -
