Auto-Off-Function
Device will be automatically switched off if no key is pressed/no
interface communication takes place for the time of the power-off delay.
The power-off delay can be set to values between 1and 120 min.; it can
be completely deactivated.
EMI
The device corresponds to the essential protection ratings established in
the Regulations of the Council for the Approximation of Legislation for
the member countries regarding electromagnetic compatibility
(2004/108/EG). Additional fault: <1%
13 Reshipment and Disposall
Dispense exhausted batteries at destined gathering places.
This device must not be disposed as “residual waste”. To dispose this device, please send it
directly to us (adequately stamped). We will dispose it appropriately and environmentally friendly.
DANGER
All devices returned to the manufacturer have to be free of any residual of measuring media and
other hazardous substances. Measuring residuals at housing or sensor may be a risk for persons
or environment
Use an adequate transport package for reshipment, especially for fully functional devices. Please
make sure that the device is protected in the package by enough packing materials.
