Khoma makulidwe a chitoliro cha chitolirochi chizikhala ndi vuto la +10% kapena -8%, khalani imodzi mwazinthu zofunikira kwambiri patebulo 3 mpaka 6 patebulopo, pokhapokha atagwirizana pakati pa wopanga ndi wogula.
-Ziyi
Kupatuka kulikonse kwa chitoliro kuchokera pamzere wowongoka, sudzapitilira 0,2% ya kutalika kwa chitoliro.
Kutulutsa kulikonse (kwina kuposa komwe kumayambitsidwa ndi Sag), mapaipi a kunja kwa 500 mm sikungapitirire 1% ya ovetur 2%, chilichonse, chilichonse chomwe sichiri zochepa.
Chonde dziwani kuti pepala latsatanetsatane la data limapereka chidziwitso chokwaniraAmasamba 719 ciges Cipes. Zofunikira zapadera zitha kukhala zosiyanasiyana kutengera polojekitiyi ndi mawonekedwe enieni a chitoliro chomwe chikufunika.
