Ukuhlolisisa
I-analog yokufaka isithiyo sokuphepha esihlukanisiweko sinikela ngokuphakelwa kwamandla okuhlukileko kwama-transmitter amabili namathathu eendaweni eziyingozi. Isiginali ye-4~20mA eyakhiwe mtjhini wokudlulisa namkha umthombo wamanje idluliselwa ukusuka endaweni eyingozi ukuya endaweni ephephileko, ngaleyo ndlela iqhuba umthwalo endaweni ephephileko. Kuma-transmitter amabili nofana amathathu weentambo nofana amatshwayo womthombo wamanje, isithiyo sokuphepha lesi sisekela ukukhulumisana okuqondileko kwesiginali yedijithali ye-Hart ebekwe phezu kwesiginali ye-4~20mA begodu inomsebenzi we-alamu yokuphuka kwentambo. Umkhiqizo lo udinga ukuphakelwa kwamandla okuzijameleko, okuphakelwa kwamandla okuhlukileko, ukungena, nokukhipha amatheminali.
