9. Service, maintenance and disposal
9.1 Calibration and new adjustment
Each device is adjusted and checked before delivery. The condition as supplied to the customer is
measured and stored in electronic form.
The uncertainty of measurement devices may be altered during normal operation if, for example, the
specified ambient conditions are not met. If desired, in our factory a calibration can be performed,
including a new adjustment if necessary, to assure the accuracy of the device.
9.2 Cleaning
The display and the operating keys should be cleaned in regular intervals. Use a dry or slightly moist cloth
for this.
Damage due to detergents
Detergents may not only affect the clearness of the display but also can damage the device.
Therefore, do not use detergents.
9.3 Battery
The device contains a battery for buffering the internal clock. It cannot be changed by the user. The
replacement can be done at the factory only.
If the UPS option is implemented, the associated battery pack needs to be exchanged regularly. For more
information see
chapter
9.4 Disposal
The product must be disposed in compliance with local regulations. This particularly applies to the built-in
battery for the RTC and the battery pack of the UPS option.
