How people were measuring superheat/subcool in the earlier days when there were no digital manometers (let alone "system analyzers" )? Especially the SC - how it is possible to differentiate the tenthes of a bar on a standard manifold scale (0 -30B) if "the bar" just takes 2.3mm on the scale with no tenth division inbetween (while it is important to know exactly the tenthes as each corresponds in average to a grade degree of temperature)
That is. do one need today a digital one or is it sufficient to use the standard manifold (manometers class 1.0) for that purpose?
