Frequently Asked Questions (FAQ)
What is the estimated time for replacing elements?
The unit is equipped with a self-diagnosis function called "sensor check." You can easily check the sensor's operating status by performing any key operation. We recommend that you check the sensor once every six months.
<How to check the sensor>
①Press the reset key on the front panel for more than 3 seconds.
② "rEF" will flash and the oxygen detector element will begin refreshing.
③ After "SCH" flashes, it will turn on and start the sensor check (for about 15 to 20 minutes).
④ If the oxygen sensor element is normal, the measured value will be displayed. If it is deteriorated, the display will start scrolling and the alarm lamp will light up (the alarm contact will not output). In this case, the element will need to be replaced, so please contact the store where you purchased the product. |
