Isondlo

Isexwayiso: Ngaphambi kokuvula ikhava engemuva noma ikhava yebhethri, sicela ucime amandla bese ukhipha umthofu wokuhlola kutheminali yokufaka kanye nesekethe elinganisiwe.

Ukugcinwa okujwayelekile

  • Sicela usule i-Meter case ngesikhangisoamp indwangu kanye nensipho emnene. Ungasebenzisi ama-abrasives noma ama-solvents.
  • Uma kutholakala inkinga ngeMeter, sicela uyeke ukuyisebenzisa bese uyithumela ukuze ilungiswe.
  • Ukulinganisa nokugcinwa kufanele kwenziwe ngabasebenzi abaqeqeshiwe noma umnyango oqokiwe wokulungisa.

Ukufakwa noma ukushintshwa kwebhethri (Umfanekiso 9)
Ukucaciswa kwebhethriIbhethri: 1.5V/AAA
Uma uphawu lwebhethri eliphansi luvela ku-LCD, sicela ushintshe ibhethri ngokushesha; ngaphandle kwalokho, ukunemba kokulinganisa kuzothinteka. Faka noma shintsha ibhethri ngokwezinyathelo ezingezansi:

  • Vala Imitha bese ukhipha umthofu wokuhlola kutheminali yokokufaka.
  • Gcina uhlangothi olungaphambili lweMetha lubheke phansi, khulula isikulufu kukhava yebhethri, khipha ikhava yebhethri, khipha ibhethri, bese ufaka ibhethri elisha ngokuvumelana ne-polarity efanele.
  • Faka kabusha ikhava yebhethri bese uqinisa isikulufu.I-UNI-T-UT118C-Pen-Type-Meter-fig- (17)

Imibuzo Evame Ukubuzwa

Q: Yini okufanele ngiyenze uma ngithola noma yiziphi izinkinga ngemitha noma imikhondo yokuhlola?

IMPENDULO: Uma kukhona izinkinga ezitholwayo njengemikhombandlela yokuhlola engenalutho noma isibonisi esingavamile, yeka ukusebenzisa imitha ngokushesha bese uthintana nomphakeli ukuze uthole usizo.

Umbuzo: Kufanele ngiliphathe kanjani imitha uma ngisebenza ngevolthi ephezulutages?

A: Uma usebenza nge-voltagIngaphezulu kwe-AC 30V RMS noma i-DC 60V, hlala ubambe umthofu wokuhlola ngemuva kwesigadi somunwe ukuze ugweme ukushaqeka kukagesi. Landela zonke izinyathelo zokuphepha ezishiwo kubhukwana lomsebenzisi.
