It means changing the instrument out put or reading to correspond to a standard or correct reading.

Calibrating with NaCl typically refers to preparing a solution of known concentration (usually of sodium chloride) to verify the accuracy of an analytical instrument or method. By comparing the instrument's response to the expected value, any deviation can be adjusted for, ensuring accurate measurements.
Zero-error is necessary in a measuring instrument because it ensures accuracy in measurements by accounting for any inherent discrepancies in the instrument itself. By calibrating the instrument to have a zero-error, any readings taken will be more reliable and consistent, allowing for more precise measurements to be made.
Calibrating micrometers: For quick reference the supplied test piece can be used. For calibrating a micrometer, gauge blocks are used.
'to play an instrument' (music)
Each instrument used in analytical chemistry has a useful working range. This is the range of concentration (or mass) that can be adequately determined by the instrument, where the instrument provides a useful signal that can be related to the concentration of the analyte .All instruments have an upper and a lower working limit. Concentrations below the working limit do not provide enough signal to be useful, and concentrations above the working limit provide too much signal to be useful. When calibrating an instrument for use, the experimenter must be familiar with both the lower and upper working range of the chosen instrument.
Polystyrene film is used for IR calibration because it has known peaks and absorbance patterns in the infrared region, making it a reliable reference material for calibrating IR spectrophotometers. Its stable properties and well-defined spectrum help in accurately calibrating the instrument for precise measurements of other samples.
