What is the corrective action if the Test Filter Set does not measure accurately on the DR 3900?
Summary
Test filter set catalog number LZV537 does not measure accurately on the DR 3900
Answer
If the Test Filter Set (catalog number/order code LZV537) does not measure accurately, confirm that the filter set instructions were performed correctly and that the filters are clean and in the correct orientation. If these steps do not improve the accuracy the DR 3900 will need to be sent to Hach Service.
