Preceding commonplace measurement method is manually using vernier caliper measurement.The position of slide calliper rule card has centainly random
Property, and the dynamics applied when measurement also has certain randomness, and these randomnesss can all be directly resulted in and be measured size
Error.To improve data precision, we should be ensured that is measured is the full-size of battery always, while used in guarantee
Dynamics is all.For rectangular cell, as long as battery can be obtained most using two faces of the snap-gauge contact battery of face contact
Big thickness, and for cylindrical battery, it can only also realize that line contacts from the side card of battery using snap-gauge, that is to say, that can only obtain
Two tangent line the distance between opposite to side, and can not represent and be answered in the greatest diametrical dimension actual measurement of entire side
This can 360 ° realize battery differences at diameter dimension measurement.This is not fine reality in the case where manual hand manipulation
It is existing.
