Frequently asked questions
I will post it.
About proofreading
- What kind of work is "proofreading"?
Whether the measuring instruments I usually use are working correctly.Check the current statusis.
This does not guarantee the future or the past, but if it has been proofread this year and last year and is operating correctly, we can assume it has been operating correctly for the past year.
- What is the difference between *kōsei* (proofreading) and *kōsei* (calibration)?
"Calibration" is based on the Radio Law and includes adjustment of measuring instruments, while "correction" is based on the Measurement Law."Proofreading" does not include adjustments.
- What is ISO 9001?
It is an international standard for quality management systems.
General calibration can be performed even if it does not comply with ISO/IEC 17025 calibration.- What does "traceability" mean?
As measuring instruments and standards are calibrated by higher-level standards,Ultimately, a connection with national (international) standards has been established.means it can do it.
- Does "proofreading" include adjustments and repairs?
Correction is the process of confirming the current status, while adjustment and repair areNot included.
- What are the methods for managing measuring instruments?
The common method for managing measuring instruments is to establish calibration cycles and specifications for each instrument and manage them with individual identification numbers in a measuring instrument management ledger.
Additionally, it is possible to limit the measuring instruments subject to calibration to those for which a history must be traceable or accuracy guaranteed in case of a defect in the measured object (product).- How do you set the revision period?
Measuring instrumentCan be determined at the administrator's discretion.is.
For example, the calibration period is determined based on the manufacturer's recommended calibration cycle, as well as the type, frequency of use, and characteristics of the measuring instrument.- What is the difference between "general proofreading" and "certified proofreading"?
General Proofreading
This is the process of periodically checking and recording the current status using equipment traceable to international or domestic standards.
Correction methods are stipulated arbitrarily for each business operator.
■Certified Proofreader
The process of periodically checking and recording the current status of equipment traceable to international or domestic standards is the same as general calibration. However, this is a calibration where the suitability of the calibration method and its traceability to international or domestic standards have been confirmed (accredited) by a third party (accreditation body).
ISO/IEC 17025This is a proofread that meets the requirements.- What is "ISO/IEC 17025"?
This is an international standard for testing and calibration laboratories.
Testing laboratories and calibration laboratories accredited as ISO/IEC 17025 accredited entities are competent testing laboratories and calibration laboratories.Certificate with recognized logo (JCSS, etc.)can be issued.- What is the difference between JCSS calibration and A2LA calibration?
JCSS Accreditation is a domestic accreditation body.Registered and certified by IAJapanAnd, "A2LA Calibration" isAccredited by the American Association for Laboratory AccreditationCertified calibration.
Both are compliant with the requirements of ISO/IEC 17025, so they are treated equally as calibration certificates with symbols.- What is ILAC-MRA?
This is an agreement established to ensure that test reports/calibration certificates issued by laboratories and calibration bodies in each country provide equivalent assurance in international trade.
Accreditation bodies that participate in ILAC (International Laboratory Accreditation Cooperation) arerecognize the quality of each other's certifications as equivalent through Mutual Recognition Agreements (MRAs)is established by this.- What is a specific meter?
These are measuring instruments stipulated by the Measurement Act, used for measurement in transactions or certifications, or primarily for the use of general consumers, for which it is necessary to establish standards for their structure or error. Examples of specified measuring instruments include "butcher scales," "pharmacy scales," and "water meters."
(When conducting transactions or certifications using a specified measuring instrument, a specified measuring instrument bearing a verification mark or a conformity mark indicating that it has passed verification must be used.)- What is the difference between "rdg" (reading) and "FS" (full scale) in terms of accuracy?
rdg is an abbreviation for reading.Display valueis.
FS is an abbreviation for Full Scale.Measurement range widthis.- What is the difference between calibration and verification?
Proofreading is,Measuring instrument deviation by comparing it to a standard instrumentAnd, we will check the current status of the measuring instruments.
The test isConfirm the results against a specified measuring instrument based on the Measurement Act and determine pass/fail.I will.- What types of quality standards are there based on ISO 9001?
ISO 13485
⇒Medical device industryIt is an international standard for quality management systems specializing in
IATF 16949
⇒Automotive industryIt is an international standard for quality management systems specializing in
AS9100
⇒Aerospace and Defense IndustryIt is an international standard for quality management systems specializing in
and so on.

About the service
- What is the delivery date?
PrincipleShipping within 5 business days of arrival at our companyWe will handle it at.
For measuring instruments that cannot be calibrated by our company, calibration will be performed by our partner companies, and delivery times will be discussed separately.- Can the delivery time be shortened?
Possible. For customers in a hurryExpress PlanWe have prepared.
(Costs and schedule to be discussed separately.)- What instrument is to be calibrated?
Electrical systemnot onlyMechanical EngineeringやEnvironmentalWe can handle a wide range of items, including measuring instruments.
We offer support for various measuring instruments, including field devices for plants and equipment, regardless of manufacturer or field. Please feel free to contact us first.
You can also check our track record by entering the manufacturer and model number of the instrument you wish to have calibrated below.- Is it possible to calibrate measuring instruments for which manufacturer support has ended?
Yes, it's possible. First, we will investigate whether we can perform the proofreading.
Please feel free to contact us.- Yes, we can support units from overseas measurement instruments (e.g., inch-pounds).
We can accommodate that. As it is an overseas product, we may ask you to provide specifications.
- Is it possible to comply with JIS standards in addition to manufacturer standards?
Regarding a certain device, pass/fail determinationIs it possible to do it according to JIS standards?For more details, please inquire.
Measurements are based on our company's standards.- Are the corrected documents in Japanese only?
As you requested,English documentsWe also support this.
UL StandardWe can also issue documents to support this. (Costs will be discussed separately.)- Is on-site proofreading service available for business trips?
It is possible. We will proofread at your designated location on a schedule that suits your needs, in consultation with you.
Based on your consultation,We can also handle proofreading on holidays.I will do it.- What happens if you don't pass?
