This device has been designed and tested in accordance to the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and
special safety advises given in this manual will be adhered to when using it.
1.  Trouble-free operation and reliability of the device can only be guaranteed if it is not subjected to any other climatic

conditions than those stated under “Specification”.

2.  Transporting the device from a cold to a warm environment condensation may result in a failure of the function. In

such a case make sure the device temperature has adjusted to the ambient temperature before trying a new start-up.

3.  The circuitry has to be designed most carefully if the device should be connected to other devices. Internal

connection in third party devices (e.g. connection GND and earth) may result in not-permissible voltages impairing
or destroying the device or another device connected.

4.  Whenever there may be a risk whatsoever involved in running it, the device has to be switched off immediately and

to be marked accordingly to avoid re-starting. Operator safety may be a risk if:
- there is visible damage to the device or the device is not working as specified
- the device has been stored under unsuitable conditions for a longer time
In case of doubt, please return device to manufacturer for repair or maintenance.

5.  Warning: Do not use these product as safety or emergency stop device, or in any other application where failure of

the product could result in personal injury or material damage.
Failure to comply with these instructions could result in death or serious injury and material damage.

•  If the symbol "LO BAT” is displayed at the left side of display, the battery is weak, measuring can be continued for

a short  period. If  “bAt” is displayed in the main display the battery is used up and needs to be replaced. Measuring
is no more possible.

•  The battery has to be removed, when storing device above 50°C.
Hint: We recommend removing the battery if device is not used for a longer period of time! Risk of Leakage
•  Treat device and probes carefully. Use only in accordance with above specification. (do not throw, hit against etc.).

Protect from soiling, especially around the needles.

•  After switching on the instrument a segment test (all segments) is displayed, followed by the measuring unit and, if

activated, the auto power off function (please refer to configuration)

•  Dispense exhausted batteries at destined gathering places.

•  Send the device directly to us, if it should be disposed. We will dispose the device appropriate and non-polluting.
