WARNING
Customers are not allowed to modify, disassemble, or repair the instrument. Doing

Calibrations
The calibration frequency varies depending on the status of the instrument or installation
environment. We recommend that the calibration period be determined in accordance with the
status of the instrument or installation environment. Please contact your Hioki distributor to have
your instrument periodically calibrated.
15.1 Troubleshooting
If damage is suspected, check the “Troubleshooting” section before contacting your authorized
Hioki distributor or reseller.
Before having the instrument repaired
Symptom Check Item, or Cause Remedy and Reference
Unable to write data to the
SD memory card.
Unable to manipulate
folders and les, or format
the card.
The write-protected lock of
the SD memory card is in
an intermediate position.
Check the position of the write-protect lock and
disengage it.
The connector of the SD memory card is used to judge
whether the card is write-protected.
If the write-protected lock is in an intermediate position,
the determination of whether the card is write-protected
will depend on the connector.
For example, even if the instrument determines that the
card is not write-protected and allows data to be written
to it, a computer may determine that it is write-protected,
preventing data from being written to it.
