Calibration and repair
The calibration frequency varies depending on the status of the instrument or installation
environment. We recommend that the calibration frequency is determined in accordance with
the status of the instrument or installation environment and that you request that calibration be
performed periodically.
When calibration or repair is requested to Hioki, the settings will be returned to the default settings.
Before requesting calibration or repair, we recommend saving the settings of the instrument in a
USB ash drive.
Transporting the instrument
• To ensure that the product arrives safely, use the original box and packaging from when you
purchased it. However, do not use the original box if it is torn or otherwise damaged or the original
packaging if it has been crushed. Instead, use standard, commercially available packaging
materials to carefully pack the product in the same manner as it arrived after purchase.
• Please note that if you pack the product so that it is not adequately cushioned and it suffers
damage during shipment, you will be billed for the cost of repair, even if the product is still within
the warranty period.
• Be sure to disconnect all cables from the product before packing it.
• Exercise care that the product is not dropped or subject to other mechanical shock during
shipment.
