Do I really need to wait 48 hours before calibrating Trident?

[squarereefer]

I picked up a used Trident which same with the DIY Rebuild kit. I completed the rebuild yesterday, installed fresh reagents and brought the unit online for the first time. CA/Mag are reading about 100-125 points higher than my repeated salifert tests. Alk is reading about 1.5 pts low vs my Hanna.

I know there is some acceptable margin of error, but I'd like to try to tighten up the readings a bit. Do I really need to wait 48-72 hours before calibrating per the calibration task instructions?

I am still debating between calibrating with included solution vs tank water after reading a lot of posts.

I would wait until you get several consistent readings then do the calibration. I have calibrated with both the included solution and my tank water and personally I’d rather use my tank water and calibrate to my manual tests readings.

You could prolly bypass the wait time if you ran the manual tests 3 or 4 times in a single day then calibrated it.. I waited a couple days and it wasn’t off much.. I finally ran out reagents and went with the abc ones and it was way different than apex.. I used tank water to calibrate it and it was actually closer to abc than the apex reagents “using apex calibration fluid” i used salifert to confirm

Thanks everyone - I think i'll just be patient until tomorrow.
