What is calibration?

During calibration, a measuring instrument is compared with a precise reference instrument. This determines whether, and by how much, the displayed measured value deviates from the actual reference value. This deviation is documented and can be used as a basis for assessing the instrument's measurement accuracy. Depending on the instrument, calibration does not only reveal individual measurement deviations but also whether the instrument is operating within the specified tolerances and whether the measurement results remain reliable. 

Factory calibration
A factory calibration is carried out in accordance with the manufacturer’s specifications and is tailored to the specific instrument and its technical specifications. It verifies whether your measuring instrument is operating with an accuracy according to the manufactur-defined criteria. 

Accredited calibration
An accredited calibration may be required if specific standards, audits or quality management systems demand appropriate certification. Our service team will be happy to advise you on which calibration option is suitable for your instrument and your application.

Calibration or adjustment?

Calibration and adjustment are often used interchangeably, but they refer to two different procedures.

Calibration: measuring, comparing and documenting
Calibration involves checking and documenting the extent to which a measuring instrument deviates from a reference value. The instrument itself is not altered in the process.
Adjustment: setting or correcting
During adjustment, the measuring instrument is set or corrected to reduce deviations and bring the instrument back in line with the specified values.

If any anomalies are detected during a calibration, the HIOKI service team will discuss the next steps with you: for example, adjustment, maintenance or repair.

Why is it important to calibrate measurement instruments regularly?

HIOKI measuring instruments are reliable and highly accurate. However, transport, temperature fluctuations, intensive use or long periods of operation may affect measurement accuracy. For this reason, even high-quality measuring instruments should be calibrated and checked regularly.

Documented calibration helps to identify deviations at an early stage and ensures that measurement results are traceable. Particularly in quality-critical areas, it guarantees reliable testing processes and compliance with internal or external requirements.

Regular calibration helps ensure
reliable assessments of measurement results
identify measurement deviations and drift
safeguard quality processes
that test reports and documentation are traceable
reduce the risk of failure and uncertainties in the measurement process

FAQ on the calibration of HIOKI measuring instruments

During calibration, the measurement values of an instrument are compared with a reference value to determine whether and to what extent they deviate. The result is documented and helps to assess the measurement accuracy of the instrument.
Calibration helps ensure that measurement results remain reliable and traceable. It enables deviations to be detected at an early stage and supports quality processes in development, production, maintenance, and testing.
The calibration interval depends on the frequency of use, operating conditions, and internal quality requirements. Calibration is often carried out annually; for instruments that are used intensively, a shorter interval may be appropriate.
During calibration, a deviation is determined and documented. During adjustment, the instrument is adjusted or corrected to reduce this deviation.
HIOKI Europe supports the calibration of many HIOKI measuring instruments, including digital multimeters, current clamps, current sensors, data loggers, battery testers, power meters, and power analysers. Please contact us regarding your specific model.
If required, we can check whether a relevant firmware update is available for your instrument. Whether an update can be performed depends on the specific model and the currently installed firmware version.
Please use the contact form and provide us with the model name, serial number, and the required service. Our service team will review your request and inform you about the next steps.
