So...after accidently dosing 200ml within 5 minutes last night by using some crazy programing (fixed now)... Thx to @SuncrestReef ..My Trident went to SH*TZ last night; giving me Bad Cal Error readings today. Several test, calibration and it is still the same. First it reported there wasn't any water coming into the sample tube. Pulled that out and pushed out some orange creamy substance...((YUK BTW)...started another test and bam...this time the CAL reading were below the recommended reading (353)...then another test...yep you guest it BAD CA reading...reached out to the Neptune Folks...they wanted the usual pictures...I did that...but something Odd happened during the full sample test..The ICON/Neptune logo on the Trident was Flashing...not sure what that is all about...First time I ever noticed it...I included a Video for reference
