The Shurline scale is a model of simplicity. It is a cylinder and piston with a surface area of 1 square inch pushing a hydraulic jack oil. It uses a standard pressure gauge calibrated in pounds/square inch. You can easily change the capacity of the scale by swapping out the gauge since the displayed weight is an exact function of the pressure applied to the gauge. These gauges are more accurate mid-scale, so the 0-2000 gauge is reasonably accurate when the weight is between 500-1500 pounds. if you wanted to weight something that is close to 3000#, put on a 0-5000# gauge.
You can get a ballpark weight load on a wheel by placing the Shurline on the saddle of a floor jack and with everything safely blocked, jack up the axle close to the wheel and take a reading when the tire is just free of the ground.
Public scales such as those found at co-ops and grain elevators are typically a single section platform that gives only a total weight. If the scale master has the time and is willing, you can get individual weights but the process is a lot simpler if you go to a CAT scale. For those who have not done this before, the scale is segmented to provide individual weights for the steer, drive and trailer axles. Pull up so that the front axle is more or less centered on the front platform, this will put your rear axle on the 2nd segment and the trailer axles on the 3rd. The operator has a camera to see when you're on the scale and there is an intercom with a call button that is placed where the big rig drivers can reach it. For that reason and the noisy environment, I drop off the wife with her cell phone and she goes in to tell the operator what we're doing. Since our rigs are lighter than the big trucks, they sometimes have me pull forward or back a bit until they get a stable reading.
She pays and I pull off and pick her up. If I want to try an adjustment, I pull to an area away from where I might be in the big trucks' way and make my adjustment and reweigh. I think $10 is fairly universal with a $1-2 reweigh fee if done at the same scale within 24 hours. Once you get it where you want it, you shouldn't have to visit the scales again unless you change something significant.
You may want to get a weight of the solo TV as a baseline, then go back with the TT in tow.
