II. Selection CriteriaThe initial considerations for trimmer type selection are:A. Resolution of adjustmentB. Setability and time to setC. Physical and environmental conditionsD. Stability of setting requiredE. Circuit packaging requirementsA. Resolution of Adjustment1. Multiturns• Multiturns provide better resolution than single turns. Models with a longer element exhibit better resolution than those with a short element. Typical multiturn shaft revolutions range from 15 to 20 turns for end to end travel.• The contact design and stability are important considerations in achieving high resolution. The contact area must be small and the contact must move smoothly in order to provide high resolution. A noisy contact will make accurate setting very difficult.• All trimmers utilize smooth cermet materials, precious metal wire brush contacts and backlash-free wiper designs that ensure high resolution setability.• Reference multiturn models:Square multiturns - 44, 64, 66,
