ONY. 207 does not involve the resonant value of capacity, Cr, but only those at thepoints of half deflection where the slope of the resonance curve is steep.This formula is therefore the most desirable one to use, and the decremeteris consequently operated in accordance with it. In Fig. 117d a… … Fig. 117a.—Kolster Decremeter. turn is, in the majority of practical cases, small as compared with the totalinductance of the circuit under test, and therefore will not affect the tuningadjustment. The coil L is the inductance of the decremeter circuit and is so arrangedthat the mutual inductance…
