During hipot calibration, the instrument is compared against a known reference source to ensure that it is measuring accurately. The calibration process involves a series of tests at different voltage levels, and the results are compared with the reference values. Calibration certificates are then provided to document the calibration process and results, providing traceability and peace of mind for the customers.

Regular calibration of hipot testers is important to ensure accurate measurements, as the accuracy of the instrument can drift over time due to factors such as physical damage, exposure to extreme temperatures or humidity, or aging of internal components. The frequency of calibration depends on several factors, including the industry, application, and the frequency of use. Typically, hipot testers should be calibrated at least once a year, but some applications may require more frequent calibration.

A reliable hipot calibration service provider can help to maintain the accuracy of the instruments and ensure that products meet the required standards.
