Patent ID: 7924544

Claim:
A method of balancing positive and negative ion output in an electrical ionizer having an ion emitter and positive and negative high voltage power supplies associated with the ion emitter, the method comprising: (a) storing a balance reference value in a software adjustable memory located in the electrical ionizer, the electrical ionizer including a wireless remote control receiver electrically connected to the software adjustable memory storing the balance reference value and responsive to a wireless remote control transmitter; (b) during operation of the electrical ionizer, comparing the balance reference value to a balance measurement value taken by an ion balance sensor located close to the ion emitter; (c) automatically adjusting at least one of the positive and negative high voltage power supplies if the balance reference value is not equal to the balance measurement value, the adjustment being performed in a manner which causes the balance measurement value to become equal to the balance reference value; (d) during operation of the electrical ionizer, measuring the actual ion balance in the work space near the electrical ionizer; and (e) adjusting the balance reference value if the balance measurement value is equal to the balance reference value and the actual measured ion balance is not zero, the adjustment being performed in a manner which causes the actual measured ion balance to approach zero, the adjusting step comprising using the wireless remote control transmitter to adjust the balance reference value in the software adjustable memory via the wireless remote control receiver while monitoring the actual measured ion balance to cause the actual measured ion balance to approach zero.
