Cikakkun bayanai
Sassan tsarin: Na'urar gwajin resonance ta Pohl, mai sarrafa gwajin resonance ta Pohl, haɗakar walƙiya daban, na'urori masu auna haske guda biyu (kowanne daga nau'in A da nau'in B)
Tsarin gwajin Pohl resonance.
1. Factor na taurin kai na bazara K: ƙasa da kashi 2% na canjin lokacin girgizar ƙasa.
2. Ma'aunin lokaci (zagaye 10): daidaito 0.001s, kuskuren ma'aunin zagaye 0.2%.
3. Rage ƙarfin tsarin ba tare da damping na lantarki ba: ƙasa da 2° a kowace ruɓewar amplitude.
4. Pendulum na inji: tare da ramukan nunin faifai, nunin faifai 2°, radius 100 mm.
5. Ma'aunin girma: kuskure ±1°; hanyar auna girma: gano hoto.
6. Na'urar firikwensin daukar hoto A: gano siginar daukar hoto biyu; na'urar firikwensin daukar hoto B: gano siginar daukar hoto guda daya.
7. Gudun mota (mita mai tilastawa): 30 - 45 rpm kuma ana iya daidaitawa akai-akai.
8. Rashin daidaiton saurin mota: ƙasa da 0.05%, yana tabbatar da dorewar zagayowar gwaji.
9. Tabbatar da bambancin mataki.
Hanyoyi biyu na tantance bambancin mataki: stroboscopic da metrological, tare da karkacewar ƙasa da 3° tsakanin hanyoyin biyu.
Tsarin aunawa na hanyar metrology yana tsakanin 50° da 160°.
Matsakaicin aunawa na Stroboscopic tsakanin 0° da 180°; maimaita karkacewar auna <2°.
10. Flash: ƙaramin ƙarfin lantarki, walƙiya daban da na'urar gwaji, lokacin walƙiya mai ci gaba da 2ms, launi ja mai jan ido.
11. Ƙarancin hayaniya, babu wata matsala ko rashin jin daɗi yayin gwaje-gwajen rukuni.
Mai sarrafa gwajin ra'ayi na Pohl.
1. Ana amfani da na'urar sarrafawa ta musamman ta gwaji don tattarawa da nuna bayanai; ana amfani da babban allon LCD mai matrix, tare da menus don jagorantar gwajin, yana ba da bayanin kula (littafin umarnin lantarki), da kuma nunawa da duba bayanan gwaji.
2. Tsarin sarrafawa na musamman don strobes.
