1.8. Requirement of Calibration

Calibration is the activity of checking or measuring and comparing with a specific standard
reference instrument. It may also include adjustment of the system to bring it into alignment with
the standard.

1.9. Peripheral Devices

- External HDD (Hard Disk Drive): Useful for saving large amounts of data. Use USB3.0 device
type to transfer the data at high speed. Recommendations include using a 6TB storage device
to save around one half years data (compressed).
- UPS (Uninterrupted Power Supply): Avoid risk of DPU crash by instantaneous power failure
due to electric power company trouble, facility power or natural disaster such as
thunderstorms. When possible use an outlet ON/OFF type selection device that allows
individual device power to be set ON or OFF remotely via the internet.
