zeroed

Zeroed is the past participle of zero, used in various technical contexts to mean reset to zero or calibrated to a zero reference. In common usage, it can describe data, accounts, or instruments that have been brought to a baseline of zero.

In firearms and marksmanship, to zero a sight is to adjust aiming devices so that the point of aim matches the point of impact at a specified distance. A firearm is described as "zeroed" when this alignment is achieved, typically at a standard distance (e.g., 100 meters). This ensures consistent accuracy across ranges for that weapon and ammunition.

In computing and electronics, zeroing often means clearing data by overwriting with zeros or initializing memory to all zeros. It is a preparatory step before use to avoid residual data, and is also used in signal processing to reset a sensor or array to a baseline.

In finance and accounting, to zero out a balance or budget line means to reduce it to zero, often by offsetting entries, write-offs, or transfers. Zeroing out accounts can indicate closure, reconciliation, or the reallocation of funds.

In calibration and measurement, devices may be zeroed against a known reference to correct offsets in readings. The term can also describe processes that remove accumulated values, such as revoking previous tallies or adjustments.

The term is context-dependent; while generally indicating resetting to a baseline, its precise meaning and procedures vary across fields.
