INYATHELO 4: UKUZENZA ISIXHOBO

PHAWULA! Soloko usithi zero isixhobo phambi kokuba usisebenzise.
Ukuya ku-zero isixhobo kukho iindlela ezimbini ezikhoyo:

1. Iqhosha le-Manual Pushbutton ulungelelwaniso lwenqaku elinguziro
2. Ukulinganisa okuzenzekelayo

Ngaba isidluliseli sam sinokulinganisa okuzenzekelayo? Jonga ileyibhile yemveliso. Ukuba ibonisa -AZ kwinombolo yemodeli, ngoko une-autozero calibration.

1. Iqhosha le-Manual Pushbutton ulungelelwaniso lwenqaku elinguziro
   PHAWULA: Ukubonelela ngevoltage kufuneka iqhagamshelwe ubuncinci iyure enye phambi kohlengahlengiso lwenqaku elinguziro.
   a) Nqamula zombini iityhubhu zoxinzelelo ukusuka kumazibuko oxinzelelo abhalwe + kunye.
   b) Cofa phantsi iqhosha elingu-zero de kube ukukhanya kwe-LED (bomvu) kulayite kwaye umboniso ufundeka "zeroing" (inketho yokubonisa kuphela). (jonga umfanekiso 4)
   c) I-zeroing yesixhobo iya kuqhubeka ngokuzenzekelayo. I-Zeroing igqityiwe xa i-LED icima, kwaye umboniso ufunda i-0 (inketho yokubonisa kuphela).
   d) Phinda ufake iityhubhu zoxinzelelo uqinisekise ukuba ityhubhu yoxinzelelo oluphezulu iqhagamshelwe kwizibuko elibhalwe +, kwaye ityhubhu yoxinzelelo oluphantsi iqhagamshelwe kwizibuko elibhalwe -.

UKUQHUBEKA KWESIXHOBO

2) Ulungelelwaniso lwe-zero oluzenzekelayo
Ukuba ifowuni ibandakanya isekethe ye-autozero ozikhethelayo, akukho ntshukumo ifunekayo.
I-Autozero calibration (-AZ) ngumsebenzi we-autozero ngendlela yesekethe ye-zeroing ezenzekelayo eyakhelwe kwibhodi ye-PCB. I-autozero calibration ihlengahlengisa i-zero ye-transmitter nge-elektroniki ngamaxesha amisiweyo exesha (rhoqo kwimizuzu eli-10). Umsebenzi ususa yonke imveliso ye-drift ye-drift ngenxa ye-thermal, i-electronic, okanye i-mechanical effects, kunye nesidingo samagcisa ukuba asuse iityhubhu eziphezulu kunye ne-low-pressure tubes xa uhambisa i-original okanye i-periodic transmitter point calibration. Ukulungelelaniswa kwe-autozero kuthatha imizuzwana emi-4 emva koko isixhobo sibuyela kwimowudi yokulinganisa eqhelekileyo. Ngexesha lohlengahlengiso lwemizuzwana emi-4, imveliso kunye nexabiso lokubonisa liya kubanda kwixabiso elilinganisiweyo lamva nje. Ii-transmitter ezixhotyiswe nge-autozero calibration phantse azikhathalelwanga.

-40C UMZEKELO: UKUSEBENZA KWIMEKO KUBANDA

Isivalo sesixhobo kufuneka sivalwe xa ubushushu bokusebenza bungaphantsi kwe-0 °C. Isibonisi sidinga imizuzu eyi-15 ukufudumeza ukuba isixhobo siqalwe kubushushu obungaphantsi kwe-0 °C.
PHAWULA! Ukusetyenziswa kwamandla kuyenyuka kwaye kunokubakho impazamo eyongezelelweyo ye-0,015 volts xa ubushushu bokusebenza bungaphantsi kwe-0 °C.

UKURECYCATION/UKULAHLWA

Amalungu ashiyekileyo kufakelo kufuneka aphinde asetyenziswe ngokwemiyalelo yendawo yakho. Izixhobo ezingagunyaziswanga kufuneka zisiwe kwindawo yokurisayikilisha egxile kwinkunkuma yombane.

UMGAQO-NKQUBO WEWARANTI

Umthengisi ubophelelekile ukuba abonelele ngewaranti yeminyaka emihlanu yeempahla ezizisiweyo malunga nemathiriyeli kunye nokuveliswa. Ixesha lewaranti lithathwa ukuba liqale ngomhla wokuhanjiswa kwemveliso. Ukuba isiphene kwizinto eziluhlaza okanye isiphene sokuvelisa sifunyenwe, umthengisi unyanzelekile, xa imveliso ithunyelwa kumthengisi ngaphandle kokulibazisa okanye ngaphambi kokuphela kwewaranti, ukulungisa impazamo ngokubona kwakhe mhlawumbi ngokulungisa isiphene. imveliso okanye ngokuzisa simahla kumthengi imveliso entsha engenasiphako kwaye uyithumele kumthengi. Iindleko zokuthumela ukulungiswa phantsi kwewaranti ziya kuhlawulwa ngumthengi kunye neendleko zokubuyisela ngumthengisi. Iwaranti ayibandakanyi umonakalo obangelwe yingozi, umbane, izikhukula okanye enye into yendalo, ukunxiba okuqhelekileyo kunye nokukrazula, ukuphathwa okungafanelekanga okanye ukungakhathali, ukusetyenziswa okungaqhelekanga, ukulayisha, ukugcinwa okungafanelekanga, ukhathalelo olungalunganga okanye ukwakhiwa ngokutsha, okanye utshintsho kunye nomsebenzi wofakelo ongenziwanga umthengisi. Ukukhethwa kwezixhobo zezixhobo ezithanda ukubola luxanduva lomthengi ngaphandle kokuba kuvunyelwene ngokusemthethweni. Ukuba umenzi utshintshe ubume besixhobo, umthengisi akanyanzelekanga ukuba enze utshintsho oluthelekisayo nezixhobo esele zithengiwe. Ukufaka isibheno sewaranti kufuna ukuba umthengi ufezekise ngokuchanekileyo imisebenzi yakhe evela ekuhanjisweni kwaye echazwe kwimvumelwano. Umthengisi uya kunika iwaranti entsha yeempahla eziye zatshintshwa okanye zalungiswa ngaphakathi kwewaranti, nangona kunjalo kuphela ekupheleni kwexesha lewaranti yemveliso yokuqala. Iwaranti ibandakanya ukulungiswa kwenxalenye enesiphene okanye isixhobo, okanye ukuba kuyimfuneko, inxalenye entsha okanye isixhobo, kodwa hayi ukufakela okanye ukutshintshiselana ngeendleko. Naphantsi kwayo nayiphi na imeko umthengisi unoxanduva lokuhlawula imbuyekezo yomonakalo ongathanga ngqo.
