Repair and Calibration Service Information by Product

-1. Calibration with adjustment (Post-adjustment accuracy guarantee)

■ What is adjustment?When Hioki adjusts your instrument, we first evaluate its performance by comparing actual measurement results with predetermined standard values. If there is any discrepancy between the two, the instrument’s values will be corrected so as to bring them into alignment with the reference values.

Post-adjustment accuracy guarantee

This is Hioki’s standard recommended calibration service. Even if your product's pre-adjustment calibration results fall within the applicable standards, Hioki will still adjust your instrument for optimal performance and repeat the calibration process. In case of calibration with adjustment, accuracy is guaranteed during the suggested calibration frequency period except for some products.

-2. Calibration (Record of results only)

■What is calibration?

When Hioki calibrates your instruments, the relationship between the value that indicates for a given standard, standard sample, or other defined specimen, and that sample’s true value is calculated.

This service consists of calibration only.

2. Repair

Hioki will conduct a series of failure diagnostics to assess the state of your instrument’s appearance and internal operation. Then, our technicians will repair, adjust, and calibrate your instrument based on the results. Upon request,a record of test results (test report) for the calibration that was performed after repair and adjustment can also be issued.
Repair work is covered by a six-month warranty (when the same defects has been found), and accuracy is guaranteed in accordance with the same terms and provisions as the post-adjustment accuracy guarantee that is offered after calibration with adjustment.
