How does 1 create a check to just get some SNMP values from a device

I have looked at them but I am not seeing a correlation.
For example here is an Uptime.
OID=.1.3.6.1.4.1.46202.1.1.1.3.0, Type=TimeTicks, Value=3 days, 0:10:22.41

So how would I make this show
OID=.1.3.6.1.4.1.46202.1.1.1.3.0
Value I am guessing might be in a number and I see where I would use a function for converting.
I want to call this Uptime and display 3 days, 0:10:22.41
