Nooca hadda (4 ~ 20mA wax soo saarka):
R = (I-4) / 16 × 100%
(R waa qiimaha qoyaanka ciidda, waxaan ahay qiimaha hadda jira (mA))

Si loo xisaabiyo summada CRC:
1.Diiwaanka hore ee 16-bit waa FFFF ee hexadecimal (yacni, dhamaantood waa 1).Wac diwaankan diiwaanka CRC
2. XOR xogta 8-bit ee ugu horreysa oo leh waxoogaa yar oo ka hooseeya 16-bit CRC diiwaanka oo geli natiijada diiwaanka CRC.
3.U rog waxa ku jira diiwaanka midig hal xoogaa (dhanka hoose), ku buuxi inta ugu sareysa 0, oo hubi inta ugu hooseysa.
4.Haddii inta ugu yar ee muhiimka ahi ay tahay 0: ku celi tillaabada 3 (isbeddel mar kale), haddii inta ugu yar ee muhiimka ahi ay tahay 1: Diiwaanka CRC waxa lagu XOR oo wata A001 badan (1010 0000 0000 0001).
5. Ku celi tillaabooyinka 3 iyo 4 ilaa 8 jeer dhanka midig, si xogta 8-bit oo dhan la habeeyo.
6.Ku celi tillaabooyinka 2 ilaa 5 habaynta xogta 8-bit ee xigta.
7.Diiwaanka CRC ee ugu dambeyntii la helay waa lambarka CRC.
8. Marka natiijada CRC la geliyo qaab-dhismeedka macluumaadka, waxaa la isweydaarsadaa xoogaa sare iyo mid hooseeya, kan hoosena waa marka hore.
Ku xidh dareemaha sida ku cad tilmaamaha habka xargaha, ka dibna geli biinanka baadhista dareenka carrada si aad u cabbirto qoyaanka, oo shid tamarta iyo beddelaha ururiyaha si aad u hesho heerkulka ciidda iyo huurka goobta cabbirka.
1. Fadlan hubi in baakadu ay sax tahay oo hubi in qaabka alaabtu uu waafaqsan yahay xulashada.
2. Ha ku xidhin korantada, ka dibna shid ka dib markaad hubiso fiilooyinka.

5.Fadlan hayso shahaadada xaqiijinta iyo shahaado waafaqsanaanta, oo ku soo celi alaabta marka la hagaajinayo.
1. Marka wax soo saarka la ogaado, bandhiggu wuxuu muujinayaa in qiimihiisu yahay 0 ama ka baxsan yahay xadka.Hubi in ay jiraan caqabado ka imaanaya walxaha shisheeye.Waxaa laga yaabaa in ururiyuhu u awoodi waayo inuu si sax ah u helo macluumaadka dhibaatooyinka fiilooyinka.Fadlan hubi in xadhiggu sax yahay oo adag yahay;
