A lot more information is needed to know if it is undercharged such as;

What is the superheat?
What is the subcooling? ( if applicable)
What type of expansion device? Fixed or tev?
Air on/off indoor unit
Air off outdoor unit etc etc

if iceing suction heavily its overcharged or if it has a tev its bypassing is the coil iceing when the suction pipe is? more ifo required ie temps tev or cap type of machine superheat as above really

Welder, as Marc says, you really must start giving a few more facts if you want a decent answer.

It's a bit like me saying that I have a 36" waist, what colour are my eyes and why?

One single reading and a quick look do not a diagnosis make.

You've got 48°, is that air temperature, the temperature of your gas torch cooling down or your coffee from Costa's?
