LiCl-NaCl automatic adjustment is a 2-point adjustment in reference humidities of 11.3 %RH (LiCl) and 75 %RH (NaCl). You do not have to feed the reference values, HM70 displays the accurate value based on the measured temperature and the Greenspan table stored in the memory of HM70.
Make the adjustment as instructed in 2-point RH adjustment of HMP70 series probes (select LiCl--NaCl autom. instead of 2-point adjustment in 10 and follow the instructions on the display).
