Purchased what was listed as new on eBay rec’v it not new missing the distilled water, calibration fluid and pipettes k not end of world. Was so excited to use it as read many good reviews online but for two days now I can’t get it to give a good reading. I watched some YouTube vids on calibrating and operating s/b “simple” to use but not so simple I’m finding anyway. I calibrated using rodi water showing 1.000 which supposed to then tried “reading” a tank water sample AND then used refractometer cal solution just to be sure and keeps reading 1.000 hoping I’m just dumbing myself to death here and didn’t get a bad unit. Anyone that might have some suggestions I’d greatly appreciate it and thank you .
