Getting into the menu: switch the indicator on; when ----- appears, press & HOLD the ENTER (gear) key until -PASSWORD- shows. Set the password number with + / − (BLOCK + PLUS jumps by 100), then press ENTER — or PARTIAL + TOTAL together — to open it. To exit, set the password back to 0 and press ENTER.

Which method? Fresh install or well off → run Password 45 (calibrate with a reference weight). Just slightly off → Password 67 trims the reading ±10%. Already know the exact calibration number → key it straight in with Password 12.

Password 45 — calibrate with a reference weight

From PASSWORD 0, set 45 with + / −, then press ENTER (or PARTIAL + TOTAL). STEP1 flashes for ~2s.
-ZERO- appears. Empty the mixer completely, then press ENTER. ----- confirms the zero is saved.
-STEP2- / SET VALUE appears. Load your certified reference weight onto the mixer.
Key the exact weight of that reference (in kg or lb) with + / − (BLOCK + PLUS = +100), then press ENTER.
----- then -CALIB OK- means the new calibration is saved. (An error message → repeat from step 1.)

Password 12 — set the calibration value

From PASSWORD 0, set 12, then ENTER. The current calibration value shows.
Change it with + / − if needed. The value depends on the load cells’ number and capacity — contact Dinamica Generale; full systems ship pre-gauged.
Press ENTER. -CALIB OK- confirms and the indicator returns to password 0.

Password 67 — fine-tune the weighing (±10%)

From PASSWORD 0, set 67, then ENTER.
CPC appears. Set the correction percentage with + / − — range -10.0% to +10.0%, 0.1% steps.
Press ENTER. -CALIB OK- confirms. Use this when a known load reads slightly high or low.

Daily tare: from weighing, press the >0< ZERO key and hold until TARE OK — zero the mixer before every load.
