Chapter 9 Maintenance and Service
9.1 Troubleshooting
Never modify the instrument. Only Hioki service
engineers should disassemble or repair the instrument. Failure to observe these
precautions may result in fire, electric shock or injury.
If damage is suspected, check the ‘Trouble-shooting’ section before contact Regal
Electro.
The instrument contains a built-in backup lithium battery, which offers a service
life of about ten years. If the date and time deviate substantially when the
instrument is switched on, it is the time to replace that battery. Contact Regal
Electro.
When sending the instrument for repair, remove the batteries and pack carefully to prevent
damage in transit. Include cushioning material so the instrument cannot move within the package.
Be sure to include details of the problem. Hioki and Regal Electro cannot be responsible for damage
that occurs during shipment.
