Heerkulka gaashaaman ee birta qaaliga ahinta badan waxay ka kooban tahay qolof bir ah oo qaali ah, walxo dahaar ah, walxo silig dipole ah.

Astaamaha thermocouples-ka birta qaaliga ah ee gaashaaman waxaa lagu soo koobi karaa sidan soo socota:

(1) Iska caabbinta daxalka

(2) xasillooni wanaagsan oo ku timaadda awoodda kulaylka, isticmaalka muddada-dheer ee awoodda kulaylka ayaa yar;

(3) Xadka sare ee heerkulka isticmaalka waa mid sarreeya;

(4) Dhamaadka thermocouple-ka ee gaashaaman ayaa si hermetically loo shaabadeeyey, gaas haraaga ahna gudaha kuma jiro

(5) Iska caabin heer sare ah oo dahaarka leh, heerkulka birta qaaliga ah ee gaashaaman ee heerkulka qolka ayaa gaari kara wax ka badan 50MΩ;

(6) Tilmaamaha badeecada, agabka tuubada ilaalinta waxaa loo farsameyn karaa iyadoo loo eegayo shuruudaha isticmaalaha

(7) Si fudud loo leexiyo, dabacsanaan wanaagsan, rakibid fudud

(8) U adkaysta cadaadiska iyo gariirka;

(9) Waqti gaaban oo jawaab celin kuleyl ah; cimri dheer oo adeeg ah
