Does anybody have a clue how tension is maintained using a spring scale and a two-person taping crew?
With a two-person crew, one person must hold proper tension and read the tape at the same time. I have tried this and found it to be a hard thing to do. Generally the scale is offset from the mark on the tape, and it's nigh impossible to hold proper tension while being sure both readings can be read.
In my opinion it is a three-person job, yet I see many applications for certification of a calibration course that mention only a two-person crew.
I've never done a decent job of maintaining proper tension while simultaneously reading both scale and tape. Can anyone explain how this is done?
