Im going to return the meter.
the USB is totally rusted and only connects 1 out of 10 times to both my PC and my MBP. When it does connect, it reads between 5-30 seconds before erroring out. Unfortunately, I was going to map out the entire tank so this isn't going to work due to how infrequently it reads and out sporadically it disconnects.
I'll drop it back off later today.
