1
adjusting instruments for accuracy
The process of testing and setting a tool or machine so that it shows correct measurements.
Usage pattern:
the calibration of [a device]
Common mistake:
Learners sometimes confuse "calibration" with "calculation" because they look and sound similar. "Calibration" is about adjusting equipment for accuracy, while "calculation" is about doing math to find an answer.
Synonyms
adjustment (A more general word; it can mean any kind of change, not specifically to ensure measurement accuracy.)
Antonyms
misalignment (Suggests that a device is not set correctly, leading to inaccurate measurements, which calibration is meant to prevent or fix.)
Collocations
perform calibration

|calibration standard

|initial calibration
|regular calibration

Examples
- The lab requires annual calibration of all thermometers to maintain accuracy.
- After replacing the sensor, the technician ran a full calibration of the machine.
- Poor calibration of the scale led to incorrect dosing of the medication.
- We sent the pressure gauges out for professional calibration before the safety inspection.
Learner examples
- The company does a calibration of its tools every year.
- This balance needs calibration before we can use it in the experiment.
- Good calibration is important if you want precise results.
Noun

C1
action
2
careful adjustment of strategy or response
The careful setting or changing of a plan, message, or action so it is not too strong or too weak for the situation.
Usage pattern:
the calibration of [a policy / response / message]
Common mistake:
Learners may think this sense of "calibration" is always about machines. In modern formal English, it is also often used for abstract things like policies, tone, and expectations, where it means careful adjustment to the right level.
Synonyms
fine-tuning (Less formal and slightly more conversational; widely used for adjusting plans, messages, or systems in small ways.)
Antonyms
overreaction (Describes a response that has not been properly calibrated and is too strong for the situation.)

state or settings of a device
The way a measuring tool is set after calibration, which decides how it shows numbers.
Usage pattern:
[a device]'s calibration
Synonyms
configuration (More general word for how something is set up; not limited to measurement accuracy.)
Antonyms
drift (In technical contexts, refers to the gradual change away from the correct calibration state over time.)

Learner examples
