UA52-O2 Offset Adjustment Method

Thank you for purchasing DEKIST UA52-O2.

UA52-O2 consists of an optical oxygen measurement channel protruding in the front and a channel measuring atmospheric pressure or temperature in the lower part. Oxygen sensor supports relatively long usage time by adopting optical type.
Therefore, if it is determined that an error in the oxygen measurement value has occurred due to long-term use or ambient contamination, offset adjustment is performed to correct the error in a place where clean and uncontaminated air is smoothly ventilated.

1.Connecting to a PC using a USB cable

* Check the product.
* Please distinguish it from the electrochemical oxygen sensor UA54-O2, which has the same appearance.

1. When there is an error in O2 (oxygen) value Full Range Offset You can change the value by using.
2. To adjust the offset Clean air, uncontaminated place, ventilated In place At least 30 minutes I need about.
3. Uncontaminated placeSince the general O2 (oxygen) value of is 20.9%, set the Offset value for the range beyond 20.9%. For example, in an uncontaminated place 20.9%Assuming that the current UA Calibrator O2 (oxygen)Value 19%If expressed as, the Full Range Offset value is + 1.9 %After entering and saving, the value is corrected. 20.9%It is expressed as.

Caution: Oxygen concentration may vary depending on the region.

“Sensitivity” item responsivenessMeans. Its value is set to the default value (10).
If the sensitivity value is low, the characteristics of the sensor Become sensitive Sensitivity value If high The characteristics of the sensor Dullly Works.
