Ukubuka konke
Isithiyo sokuphepha sokufakwa kwe-thermocouple sokuhlukanisa esinomsebenzi wokuvikela ukukhuphuka singadlulisela isignali ye-millivolt kusuka ku-thermocouple (TC) endaweni eyingozi iye endaweni ephephile ngo-1: 1. Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okuneziphesheli zamandla ezihlukanisiwe, okokufaka, kanye nokukhipha.

Qaphela: Umsebenzi wesitimela samandla ngumsebenzi ongawukhetha, futhi abasebenzisi kudingeka bacacise
indlela yokunikezwa kwamandla lapho ubeka i-oda
Ukukhethwa kwezixhumi zesitimela sikagesi kungabhekisela ekhasini 89 le-"Annex"
