This is for a college project. We are supposed to figure out a way to power a load without the meter registering it :/
Some students were thinking you could draw a really small amount that maybe wouldn't register. Another idea was to suck up a huge amount faster than the sampling rate and dissapate that slowly to power the load. Another idea was the 1:1 transformer but that I guess wouldn't work. Any ideas? The school allocated the funds for us to build it.

Not be able to measure it in what way, current or voltage? If it's voltage, you could max out (overload) the meter. Find out what the maximum voltage it can read then try to go beyond it. (Dangerous though) You could use a step-up transformer or you could get it to oscillate beyond what the meter can read.

Simple attach/wire your load to the input side (upstream) of the metering point rather then output side (downstream).

The instructor joked about doing that. Not allowed. We have to power something, like a light bulb without the meter registering it.
