Legacy units — applies when the numeric part of the serial number is
≤ 17,010,000. Uses Seed (S) and Core (C) directly with constant offsets.
No square-root term.

Modern units — applies when the numeric part of the serial number is
> 17,010,000. Introduces SQ = ⌊√serial⌋ as a correction factor.
Serial-dependent formulas — the same Seed and Core can yield different PINs depending on the meter.
| PIN | Formula | Notes |
|---|---|---|
| Fabrika Ayarı | −280771 + C + 2·pi − SQ | No Seed; serial-corrected |
| ATC | −421152.5 + S + 0.5·C + 3·ps + pi − 1.5·SQ | Fractional SQ weight |

| D.Servis | −417921.5 + S + 0.5·C + 3·ps + 2·pi − 1.5·SQ | K differs from ATC by −3231 |
| Devreye Alma | −143174 + C + 2·pi − SQ | |

SQ⌊√serial⌋ — integer square root of serial number
TL-269 — Uses a Step value derived from the serial number: Step = ⌊serial ÷ 255⌋.
Pin Sıfırlama (Reset) is not supported on this hardware.
D.Servis uses a unique formula independent of ATC.
| PIN | Formula | Notes |

Step⌊serial ÷ 255⌋ — integer division of serial by 255
SILABS — Uses fixed large constants (K values) unique to this hardware family.
ATC and D.Servis use a combined formula: (2·S + C − K) ÷ 2.
Serial number is not used in any calculation.
| PIN | Formula | K constant |
|---|---|---|
| Fabrika Ayarı | C − 283621 | K = 283621 |
| ATC | (2·S + C − 848387) ÷ 2 | K = 848387 |
| Malzeme | S + 58583 | K = 58583 |
| D.Servis | (2·S + C − 839457) ÷ 2 | K = 839457 (≠ ATC K) |
| Devreye Alma | C − 146024 | K = 146024 |
| Pin Sıfırlama | S + 38677 | K = 38677 |
| Bakım PASS | C − 280196 | K = 280196 |
