Service for Calibration and Adjustment
Because it verifies the condition of an instrument, calibration is like a health checkup. Specifically, the process involves checking the condition of an instrument at a particular point in time by comparing the ideal value indicated by a standard and the value indicated by the instrument being calibrated.
Hioki’s calibration services were updated effective April 2022.
When an instrument is calibrated and its measured values are found not to satisfy internal Hioki standards, the instrument is adjusted. Through the ongoing use of calibration services offered as only an instrument manufacturer can, customers are able to use their instruments with peace of mind while maintaining their precision.
This calibration service will allow us to return products to customers with minimal downtime, since there are no work interruptions.
- If you do not wish your instrument to be adjusted, please let us know when you request calibration. Your product will be returned without adjustment, even if the calibration report indicates a FAIL judgment (non-compliance).
- This service does not extend to products that cannot be adjusted or to discontinued products.
Guarantee after Calibration Service*¹
If a customer reports a loss of accuracy after calibration while the instrument in question is covered by the recommended calibration interval and we are able to verify the issue, we will adjust the instrument free of charge.
(If the product is subject to a regular calibration request, we will adjust it as part of the calibration fee.)
- *1:Not all products are covered by this guarantee.
- If a loss of accuracy is caused by a part’s having reached its service life or deteriorated, fees will apply to the repair.
- If the loss of accuracy is deemed likely to have been caused by damage or by the operating or storage environment, fees will apply to the repair.
- If a product is deemed likely to experience a loss of accuracy after shipment, for example due to the end of the repair period, we may contact the customer and decline to offer a guarantee.
- The guarantee applies to products that are calibrated at Hioki.
Calibration Expiration (Calibration Interval)
Values obtained on the date of calibration are used as the calibration results. When calibration expires (i.e., the calibration interval) depends on the customer’s operating conditions and environment. Consequently, the customer is ultimately responsible for determining calibration expiration while taking into account the calibration interval recommended by Hioki.
Hioki recommends that each product’s accuracy guarantee period be treated as the recommended calibration interval.
Calibration values will be optimized so that the instrument satisfies Hioki’s internal standards.
If an instrument is adjusted as part of calibration service
Values are optimized so that they satisfy Hioki’s internal standards to reduce the risk that they will subsequently exceed the tolerance.

Documents Hioki can issue:
ISO/IEC 17025 calibration (JCSS)
Hioki Headquarters is an international MRA-cmpliant, JCSS-accredited calibration service provider that meets ISO/IEC 17025 requirements. As such, we can issue JCSS calibration certificates bearing the international MRA-compliant JCSS mark, which means they are recognized worldwide.
JCSS calibration and international MRAs
JCSS is a registration program designed to ensure that calibration service providers possess the technological skills needed to perform calibration that complies with measurement-related laws and the requirements imposed by ISO/IEC 17025.
Registered service providers are entitled to perform JCSS calibration and issue calibration certificates bearing the JCSS symbol mark. Such certificates serve as evidence of the calibration service provider’s technological skills and traceability. JCSS calibration service providers who have been certified as international MRA-compliant can issue calibration certificates bearing the ILAC-MRA and IA Japan symbol marks. Such certificates can be used as official documents whose validity is recognized worldwide.
An MRA is a mutual recognition agreement. IA Japan belongs to ILAC and APAC which includes NVLAP, A2LA, UKAS, DKD, and NATA. Calibration certificates issued by calibration service providers that have been certified as MRA-compliant by IA Japan are treated as equivalent to calibration certificates recognized by member certification entities in member countries.
ILAC: International Laboratory Accreditation Cooperation
APAC: Asia Pacific Accreditation Cooperation
IAAC: Interamerican Accreditation Cooperation
EA: European Cooperation for Accreditation
SADCA: Southern African Development Community Accreditation
When is JCSS necessary?
JCSS calibration is the solution when you need calibration that includes inaccuracy data, for example ISO/IEC 17025 calibration, ILAC calibration, MRA calibration, or IATF 16949 calibration.
- Calibration of instruments used by automobile (or motorcycle) manufacturers and part suppliers
- Calibration of instruments used in UL product certification
- Calibration of instruments as required by Japanese law (for radiation therapy) or ministerial ordinance (for pharmaceuticals and quasi-drugs)
