The easiest is the direct method where you use a tension dynamometer or strand or Loos tension meter. The Loos is \$59.95 - the other two are \$900 and \$2300 respectively. There are two indirect methods you can use. One is the Pulse Method where you give the guy wire a sharp jerk (or swing) and you measure the return with a stop watch and crank the time along with the total weight of the guy, the guy length, vertical and horizontal measurements and some other data into a formula. The other indirect method is the Tangent Intercept method where in addition to much of the aforementioned information you need the guy angle at the anchor (probably best done with a transit) and, again, it's all cranked into a formula. These methods are obviously used for TALL towers with BIG guy wires - not your typical ham installation. More info and the formulas are in the TIA-222-F "Structural Standards for Steel Antenna Towers and Antenna Supporting Structures". The obvious accurate, quick, inexpensive and *only* way to measure ham tower guy wire tensions is with a Loos.
