Imanuwali Yomsebenzisi Yokulandela I-alamu Yeziteshi Ezine

Isingeniso

Le manuwali inikeza imiyalelo enemininingwane yokusebenza nokugcinwa kwe-Traceable Four-Channel Alarm Timer, Model 90225-35. Lolu cingo luklanyelwe ukusetshenziswa elabhorethri, lunikeza amandla anembayo wesikhathi kuwo wonke amashaneli amane azimele wezinhlelo zokusebenza ezihlukahlukene.

Izici

• Isibali sikhathi esilinganiselwe se-alamu seziteshi ezine ukuze sisetshenziswe elabhorethri
• Inkumbulo ibuyisela isibonisi esikhathini esidlule sokubala wehla esihleliwe ngokuthinta inkinobho
• Ama-alamu anomsindo owengeziwe azwakala iminithi elingu-1
• Kufaka phakathi isitifiketi se-NIST-Traceable esivela kulabhorethri yethu yokulinganisa ye-A2LA egunyaziwe (1750.01)

Setha

Ukufakwa Kwebhethri

Isibali sikhathi sisebenza ngamabhethri ajwayelekile. Ukufaka noma ukushintsha amabhethri:

1. Thola indawo yebhethri ngemuva kweyunithi.
2. Vula ikhava yegumbi.
3. Faka amabhethri amasha, ubheka i-polarity elungile (+/-) njengoba kukhonjisiwe ngaphakathi kwekhompathimenti.
4. Vala ikhava yengxenye yebhethri ngokuphephile.

Isithombe: Emuva view Yesibali Sesikhathi Se-Alarm Yeziteshi Ezine Ezilandelekayo, egqamisa ikhava yengxenye yebhethri eyindilinga ngakwesokudla.

Amandla Okuqala Avuliwe

Ekuvuleni kokuqala noma ngemva kokushintshwa kwebhethri, isibonisi sizobonisa isikhathi samanje noma okumisiwe kube ngu-0:00:00. Isibali sikhathi manje sesilungele ukusebenza.

Imiyalelo yokusebenza

Kuphelileview Yezilawuli

Isithombe: Ngaphambili view ye-timer, ebonisa isikrini se-LCD nazo zonke izinkinobho zokulawula. Izinkinobho zifaka u-T1, T2, T3, T4, CLOCK phezulu, kanye no-H, M, S, C, QALA MISA ngezansi.

Isibali sikhathi sinezinkinobho ezimbalwa zemisebenzi eyahlukene:

• T1, T2, T3, T4: Ikhetha isiteshi sesikhathi esifiswayo.
• IWASHI: Iguqula phakathi kwesibonisi sewashi nesibonisi sesikhathi, futhi isetshenziselwe ukusetha iwashi.
• H (Amahora): Imisa amahora wokubala wehle/ukubala.
• M (Amaminithi): Imisa amaminithi wokubala wehle/ubale phezulu.
• S (Amasekhondi): Imisa imizuzwana yokubala wehle/ukubala phezulu.
• C (Sula): Isula isikhathi esimisiwe sesiteshi esikhethiwe.
• QALA / YEKA: Iqala noma imise isibali sikhathi esikhethiwe.

Isithombe: Ukuvala izinkinobho 'H' (Amahora) kanye no-'M' (Amaminithi), asetshenziselwa ukusetha amanani esikhathi.

Isithombe: Vala inkinobho ethi 'QALA MISA', esetshenziselwa ukuqalisa noma ukumisa okwesikhashana imisebenzi yesikhathi.

Isithombe: Vala inkinobho ethi 'IWASHI', esetshenziselwa ukusetha kanye viewngesikhathi samanje.

Ukusetha Isikhathi Esibalayo

1. Cindezela enye yezinkinobho zesiteshi (T1, T2, T3, noma T4) ukuze ukhethe isibali sikhathi osithandayo. Isibonisi sizobonisa inkomba yesiteshi ekhethiwe.
2. Cindezela inkinobho H, M, futhi S izinkinobho zokusetha isikhathi sokubala wehle osifisayo. Umshini ngamunye wokucindezela unyusa inani. Bamba inkinobho ukuze ukhule ngokushesha.
3. Cindezela inkinobho QALA/YIMA inkinobho ukuqalisa ukubala wehle.
4. Uma i-countdown ifinyelela kuziro, i-alamu enomsindo owengeziwe izokhala iminithi elingu-1.
5. Ukumisa i-alamu, cindezela noma iyiphi inkinobho.
6. Ukuze ukhumbule isikhathi sokubala wehle esihleliwe sesiteshi, cindezela inkinobho yesiteshi esihambelanayo (T1-T4) ngemva kokuba isibali sikhathi simile.

Ukusebenzisa Njengesibali Sesikhathi Sokubala (Iwashi elimiswayo)

1. Cindezela enye yezinkinobho zesiteshi (T1, T2, T3, noma T4) ukuze ukhethe isibali sikhathi osithandayo.
2. Qinisekisa ukuthi isiteshi esikhethiwe siyasulwa (umbukiso ukhombisa 0:00:00). Uma kungenjalo, cindezela inkinobho C inkinobho.
3. Cindezela inkinobho QALA/YIMA inkinobho ukuqala ukubala phezulu.
4. Cindezela inkinobho QALA/YIMA inkinobho futhi ukuze umise isikhashana ukubala.
5. Cindezela inkinobho C inkinobho ukusula isikhathi count-up.

Ukusetha Iwashi

1. Cindezela bese ubamba i IWASHI inkinobho kuze kube isibonisi sesikhathi siqala ukukhanya.
2. Sebenzisa i- H, M, futhi S izinkinobho zokusetha isikhathi samanje.
3. Cindezela inkinobho IWASHI inkinobho futhi ukuze uqinisekise futhi uphume kumodi yokusetha iwashi.

Isondlo

Ukuhlanza

Sula isibali sikhathi ngesithambile, damp indwangu. Ungasebenzisi izinto zokuhlanza ezidukayo noma ucwilise iyunithi emanzini.

Ukushintshwa Kwebhethri

Uma isibonisi sifiphala noma i-alamu iba buthaka, sekuyisikhathi sokushintsha amabhethri. Bheka esigabeni esithi "Ukufakwa Kwebhethri" ngaphansi kokuthi Ukusethwa ukuze uthole imiyalelo.

Ukuxazulula inkinga

Isibali sikhathi asiphenduli

• Hlola ukufakwa kwebhethri futhi uqinisekise ukuthi amabhethri masha.
• Cindezela inkinobho C inkinobho ukusula noma yiziphi izilungiselelo zangaphambilini.

I-alamu ithule kakhulu noma ayizwakali

• Shintsha amabhethri.
• Qinisekisa ukuthi isibali sikhathi asikho endaweni lapho umsindo uvalekile khona.

Ukubonisa akunalutho noma kunephutha

• Shintsha amabhethri.
• Uma inkinga iqhubeka ngemva kokushintshwa kwebhethri, xhumana nokwesekwa kwamakhasimende.

Imininingwane

Iwaranti kanye Nokusekela

Lo mkhiqizo uza nesitifiketi se-NIST-Traceable, esiqinisekisa ukunemba kwawo kokulinganisa. Ukuze uthole imininingwane ethile yewaranti noma ukwesekwa kobuchwepheshe, sicela ubheke amadokhumenti afakwe nokuthenga kwakho noma uthinte isevisi yamakhasimende yakwa-Cole-Parmer.

Ukuze uthole ulwazi olwengeziwe noma ukwesekwa, sicela uvakashele ezomkhiqizi webisayithi noma uxhumane nomnyango wabo wesevisi yamakhasimende.
