The optical display may be difficult to read under adverse light conditions,
e.g. in direct sunlight.
In case of arbitrary mechanical deformation or modifications of the measuring
device’s electronic components, the warranty will be void.
Be careful when handling flammable or caustic liquids. In that case, wear
safety gloves, goggles and an apron. Only measure in well-ventilated environ-
ments!
Only immerse the sensor head in the voltageless liquid! Do not immerse the
device more than 45 mm.
Inserting/changing the batteries
For operation the DO-100 requires a battery (type 9V block, not supplied with
the device).
Proceed as follows to insert or change the batteries:
- Unscrew the battery compartment screw on the back of the device and
take off the battery compartment cover.
- Insert a new 9V block battery or replace the flat battery with a new one of the
same type. If possible, use alkaline batteries. They ensure a longer service life.
- Then carefully close and screw down the battery compartment cover
again.
It is necessary to change the batteries when the battery symbol appears on
the LCD. This symbol indicates that the battery is flat.
Once this battery symbol appears on the LC display, the battery
must be changed to ensure sufficient measuring accuracy.
To prevent damage to the device from leaking batteries, remove the batteries
from the device if you will not be using it for a longer period. For the same rea-
son, we recommend that you remove flat batteries immediately.
