calibrálo

Calibrálo is an imperative expression in Spanish that translates as “calibrate it.” It combines calibrar, to calibrate, with the second-person singular affirmative form calibra and the attached direct object pronoun lo. The resulting one-word command is commonly found in technical manuals, equipment guides, and instructional dialogue to instruct a user to adjust a device, sensor, or instrument.

Etymology and form: The base verb calibrar derives from calibr- plus the infinitive -ar; in the imperative, tú form is calibra, and adding lo yields calibrálo. Orthographic conventions vary; some spellings use calibrálo with a diacritic to indicate the stress pattern, while others separate the words as calibra lo in more formal typography. The pronoun lo substitutes for a masculine or neuter object previously mentioned, such as “dispositivo” or “sensor.”

Usage: It is most common in professional settings—industrial, laboratory, and consumer electronics—where precise adjustment of measurement tools is required. The form is informal and directed at a single person.
