Mibvunzo Inowanzo bvunzwa
Nhamba yemuenzaniso ndiyo ΔT rating here?
Pamutsetse wedu weSatellite, nhamba dzinoratidza kirasi ye triggering-advance — ESE2500 kuenda kukirasi ye25 μs, ESE4500 kusvika 45 μs, ESE6000 kusvika 60 μs.

Ndingasanganisa ESE2500 neESE6000 padenga rimwe chete here?
Ehe, uye kazhinji ndiyo mhinduro yakanaka. Chivako chehotera chinogona kururamisa ESE6000 nepo chikamu chidiki chefekitori chichitora ESE2500.
