The heater is a 100 Ohm power resistor. The temperature sensor is built into a bridge arrangement inside the cryostat. Its resistance can be measured directly between pins E and F. It is a Pt100 sensor with a coefficient of -0.4046 Ohms per degree C. The internal LEDS have no current limiting resistors, a current of 5mA for about 1s will give a deep exposure.
