C/k = (CT primary current) / (Capacitor step kvar × 1000 / (√3 × line voltage))
Example: CT = 1000:5A, 6 steps of 25 kvar each@400V → C/k ≈ 0.40. The manual provides a lookup table to avoid math errors.
You don’t need to be a detective, but you need to be smart. Here are the best methods to get your hands on this elusive document. circutor computer 8d-96 manual
No. The manual mentions firmware updates require a factory return. The 8d-96 is not field-upgradable.
The manual includes a decision tree for programming. A simplified version: C/k = (CT primary current) / (Capacitor step
Common mistake: Forgetting the final hold-to-exit, causing unsaved changes.
Because Circutor S.A. (based in Barcelona, Spain) has been producing this model for over a decade, the manual may not be prominently displayed on their main site. However, several reliable sources exist. Polarity: Strict adherence to the polarity markings (P1/P2
Manual solution: Check the auxiliary power supply terminals. The 8d-96 often requires a separate 115V or 230V AC supply (terminals 1 & 2) independent of the measurement inputs. Also check the internal fuse—the manual shows its location (typically behind the rear terminal cover).
