Wescor/Vapro 5520 - Calibration problem
Please, could someone help me with the calibration process? I'm trying to calibrate the osmometer but I do not get the values of the standard solution. I tried already to clean the machine, and when measuring the osmolality of the 100mmol/kg standard solution, I get a lower value (49mmol/kg) but zero for contamination level. Any idea?
