Uhlolojikelele
Isithiyo sokuphepha sokuhlukanisa okokufaka se-RTD esinomsebenzi wokuvikela ukukhuphuka singaguqula amasiginali wezintambo ezimbili noma ezintathu ze-thermistor (RTD) ezindaweni eziyingozi zibe amasignali amanje angu-4-20mA futhi ziwakhiphele endaweni yokuphepha. Ingacushwa ngobuhlakani, futhi ububanzi bangempela bokumelana nokushisa bungasethwa ngesofthiwe yekhompyutha. Inemisebenzi ye-alamu yokuphuka kocingo kanye ne-alamu ephuma ebangeni.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okunokunikezwa kwamandla okukodwa, okokufaka, namatheminali aphumayo.
I-"*" imele uhlobo lokufakwayo lwe-thermistor, futhi imodeli ethile imelwe ikhodi (bona "Uhlobo Lwesiginali Yokokufaka kanye Nethebula Lobubanzi" ukuze uthole imininingwane).

Ubukhulu
Imidwebo Ehlelekile
Qaphela:
1. I-PHD-11TZ - * 1+ ayifaki ingxenye yesi-2 yokuphumayo
2. Umsebenzi wesitimela samandla uwumsebenzi ozikhethela wona, futhi abasebenzisi badinga ukucacisa indlela yokuphakelwa kwamandla lapho befaka i-oda.
Ukukhethwa kwezixhumi zikaloliwe wamandla kungabhekisela ekhasini 89 le-"Annex"
3. Lapho ufaka i-RTD yocingo emithathu, kuyadingeka ukuqinisekisa ukuthi izintambo ezintathu zinobude obulinganayo ngangokunokwenzeka.
4. Uma ufaka i-RTD enezintambo ezimbili, amatheminali okuvimbela ukuphepha 4 no-2 kufanele afinyezwe
