Notice (Kubata)
• Usashandise DC bias kune piezoelectric buzzer;kana zvisina kudaro kudzivirira kwekudzivirira kunogona kuve kwakaderera uye kukanganisa kushanda.
• Usape chero voltage yakakwira kupfuura inoshanda kune piezo yemagetsi buzzer.
• Usashandise piezoelectric buzzer panze.Yakagadzirirwa kushandiswa kwemukati.Kana piezoelectric buzzer inofanira kushandiswa kunze, ipai nzira dzekudzivirira mvura;haizoshande zvakajairika kana ikaiswa munyoro.
• Usageza piezoelectric buzzer ne solvent kana kubvumira gasi kupinda mairi paunenge uchigeza;chinhu chipi nechipi chinonyungudutsa chinopinda mairi chingagara mukati menguva refu ndokuikuvadza.
• Piezoelectric ceramic material inosvika 100µm gobvu inoshandiswa mujenareta reruzha rwebuzzer.Usatsikidze jenareta yekurira kuburikidza negomba rekuburitsa ruzha zvikasadaro iyo ceramic zvinhu inogona kutyora.Usatutira piezoelectric buzzers usina kurongedza.
• Usashandise chero simba remagetsi kune piezoelectric buzzer;kana zvisina kudaro nyaya yacho inogona kukanganisa uye inokonzera kushanda kusina kunaka.
• Usaisa chero chinhu chinodzivirira kana zvimwe zvakadaro pamberi peburi rekuburitsa ruzha rebuzzer;kana zvisina kudaro kurira kwenzwi kunogona kusiyana uye kunokonzera kusagadzikana kwebuzzer kushanda.Ita shuwa kuti buzzer haina kukanganiswa nemafungu akamira kana zvimwewo.
• Iva nechokwadi chekutengesa buzzer terminal pa 350 ° C max. (80W max.) (rwendo rwesimbi inotengeswa) mukati memasekonzi mashanu uchishandisa solder ine sirivheri.
• Dzivisa kushandisa piezoelectric buzzer kwenguva yakareba apo chero gasi rinoparadza (H2S, nezvimwewo) riripo;kana zvisina kudaro zvikamu kana jenareta inonzwika inogona kuita ngura uye inokonzera kushanda kusina kunaka.
• Chenjerera kuti usadonhedze piezoelectric buzzer.
