it is advised so to prevent wear and tear of the apparatus, however for accurate reading instead of tapping the jockey on the potentiometer wire, you can simply just slide the jockey. But while doing so avoid applying a lot of pressure.

@stutishah8748 4 жыл бұрын
6 strings means 5 complete strings (i.e. 500 cm) and the rest 66 cm are on the 6th string. You will get 600 at the end of the 6th string and 600+ to 700 readings on the 6th string
@730.mayurimanoj9 4 жыл бұрын
For the first five strings the value is 500 (5x100) and as the sixth string is an even number , u should take the reading from right to left then it will come 500 + 66. NOTE that if it is an odd string (1,3,5,7,9)then u should measure from left to right and if an even string(2,4,6,...) then from right to left.
