Testing the resistor of the external electrode for sealing chamber control

  1. Ohmmeter available.
  1. Measure the resistance.
  2. Measured values “infinite (∞)”: Monitoring device OK.
  3. Measured value ≤ 30 kOhm: Water in oil. Change oil.
  1. Resistance checked. If the measured value still deviates after the oil change, consult customer service.
