In most cases, they are calibrated by a trained service technician who puts the heads on a fixture and "zero's" the sensors. This is done through a special sequence that is built into the administration features of the machine.
On late models - about year 2002 and newer, a user calibration feature is available. This requires placing the heads on a vehicle, taking a snapshot of the raw data, then swapping them around on the wheels. Another snapshot is taken and the machine compares the reading and calibrates as necessary.
With a little training the end user could calibrate his onw heads on older systems, but will require procuring a calibration fixture which may be hard to locate.
I would suspect most techs would charge around $100 to do a cal, but that may be off a little.
Four wheel is preferred.
Yes, wheel alignment machines do need to be calibrated.
A wheel alignment is what syncs your steering wheel with your wheels. It ensures your car will drive straight when your steering wheel isn't turned.
if you have independent suspention front and rear chances are a 4 wheel alignment can be done typically front wheel drive vehicles but not all.

Before-a bad alignment cannot "unbalance" a wheel, but an unbalanced wheel, if bad enough, can throw off an alignment.
when i calibrate my FMC wheel balancer i only get cal o not cal good at the end
A two wheel can be done, but a four wheel is preferred.
Wheel alignment 40-60 $ depending on where you go. Wheel balancing 20 $
The price of a wheel alignment at Jiffy Lube will vary from location to location as well as the make and model of the vehicle. Prices for a wheel alignment range anywhere from $40.00 to $80.00.
A frame rack is primarily designed for straightening vehicle frames after collisions, rather than performing wheel alignments. However, it can be part of the wheel alignment process by providing a stable platform for measuring alignment angles. For accurate wheel alignment, specialized alignment equipment, such as alignment machines with sensors, is typically required to ensure precision in adjusting the vehicle’s suspension components.
