Hninhnak sensor signal cu a dang tein chiahmi himnak khamnak chungah luhter a si, cu nih cun ttihnung hmun ah hninhnonak sensor nih a chuahmi negative voltage signal kha a himnak hmun ah 1: 1 in a kuat khawh, cun AC le DC signal kha a kuat khawh, cu nih cun hnahnawhnak dohnak riantuannak sang a ngei.
Hi thilri nih hin amah tein thazaang peknak a herh, cun thazaang peknak, luhnak le chuahnak cu aa then.
