A friend has a Park Tool spoke tension meter, which he has not used yet. I borrowed it to check my three sets of wheels. My winter wheels are a set of new Fulcrum Racing 5 LG, I have around 100km on them. Front wheel has 16 to 17 on the scale which is OK. The back wheel has 17 to 18 on the drive side and 13 or 14 on most and down to around 6 in about three. Tried to bring the NDS up to around 14 and the DS stayed at 17/18. I noticed a wobble in the wheel and the rim now was pulling to the NDS side. Returned the wheel to it orignal settings and the rim is true and centred......Next tried out my early 2017 Fulcrum quatro LG wheel set which have done around 2000km, and front OK at 16/17 and the rear was ok as well, DS at 17/18 and the NDS at 15...Next checked my Mavic Ksy Elite 15c 2014 wheelset. Front ok at 14. Back was like the Fulcrum ,5 NDS around 13 with about three at about 6.....Wheels seem ok, just wondering in case I will crake or twist the rim out on the road.
