10.1  Repairs, Inspections, and Cleaning

WARNING

 

„

Do not attempt to modify, disassemble, or repair the instrument 

yourself.

There are some areas inside of the instrument where high voltage is present. These 

areas may expose the operator to electric shock or cause fire.

CAUTION

 

„

Observe the following when shipping the instrument. 

 • Remove test leads from the instrument. 
 • Attach a description of the malfunction.
 • Use the packaging in which the instrument was initially delivered and then pack that in 

an additional box. 

Failure to do so could cause damage during shipment.

Calibration

The calibration period varies with the conditions and environment of use. It is recommended 
to determine a calibration period based on those factors and to have the instrument regularly 
calibrated by Hioki. Please contact your Hioki distributor to have your instrument periodically 
calibrated.

Backing up data

When repairing or calibrating the instrument, we may initialize it or update it to the latest software 
version. It is recommended to record the measurement conditions and system settings before 
requesting a repair.
