Amanye amacandelo anganxulumananga nokhuseleko anokuthengwa kwabanye ababoneleli ukuba nje benawo
zilingana necandelo lokuqala (qaphela ukuba iindawo ezikhethiweyo kufuneka zithengwe kuphela ngeKeithley ukugcina ukuchaneka kunye nokusebenza kwemveliso). Ukuba awuqinisekanga malunga nokusebenza kwecandelo lokutshintsha, tsalela i-ofisi yaseKeithley ngolwazi.
Ngaphandle kokuba kuphawulwe ngenye indlela kwimveliso ekhethekileyo yoncwadi, izixhobo zikaKeithley ziyilelwe ukusebenza ngaphakathi kuphela, kwezi ndawo zilandelayo: Ukuphakama okanye ngaphantsi kwe-2,000 m (6,562 ft); ubushushu 0 ° C ukuya ku-50 ° C (32 ° F kuye kwi-122 ° F); kunye nongcoliseko 1 okanye 2.
Ukucoca isixhobo, sebenzisa ilaphu dampened ngamanzi ahlukanisiweyo okanye ngobulali, isicoci esisekwe emanzini. Coca umphandle wesixhobo kuphela. Musa ukusebenzisa isicoci ngokungqalileyo kweso sixhobo okanye uvumele ulwelo lungene okanye luphalaze kweso sixhobo. Iimveliso eziqulathe ibhodi yesekethe ngaphandle kwetyala okanye i-chassis (umzekelo, ibhodi yokufumana idatha ukufakelwa kwikhompyuter) akufuneki ifune ukucocwa ukuba iphathwe ngokwemiyalelo. Ukuba ibhodi iye yangcoliseka kwaye ukusebenza kuyachaphazeleka, ibhodi kufuneka ibuyiselwe kumzi mveliso ukuze icocwe / isebenze ngokufanelekileyo.
Uhlaziyo lokhuselo lokhuseleko ukusukela ngoJuni 2018.
