1. Ntlha ea manganga ea selemo K: phetoho e ka tlase ho 2% nakong ea ho sisinyeha ha mahala.
2. Tekanyo ea nako (lipotoloho tse 10): ho nepahala 0.001s, phoso ea tekanyo ea potoloho 0.2%.
3. Ho senya tsamaiso ha ho se na motlakase oa motlakase: ka tlase ho 2 ° ka ho senyeha ha amplitude.
4. Mechanical pendulum: ka li-slots tsa indexing, indexing 2 °, radius 100 mm.
5. Tekanyo ea amplitude: phoso ± 1 °; mokhoa oa tekanyo ea amplitude: ho lemoha photoelectric.
6. Sensor ea photoelectric A: ho lemoha matšoao a mabeli a photoelectric; photoelectric sensor B: ho lemoha matšoao a le mong a photoelectric.
7. Lebelo la likoloi (maqhubu a qobellang): 30 - 45 rpm le ho fetoha ka mokhoa o tsoelang pele.
8. Ho se tsitse ha lebelo la likoloi: tlase ho 0.05%, ho netefatsa potoloho e tsitsitseng ea teko.
