8. Maintenance and Precautions
8.1 Power Check
When the power is low, the low battery indicator appears. At this moment, users should replace the
battery in time, or it will affect the measuring accuracy. Please note that the backlight will use
additional power. If the battery is too low, the backlight will automatically shut down in order to ensure
reliable service.
For use on site it is recommended to make available a set of replacement batteries.
Note: If the gauge is not in use for a longer period of time, make sure to remove the batteries
in order to prevent battery leakage and damage to the gauge.
8.2 Precautions
8.2.1 General Precautions
Keep the gauge away from strong vibrations. Do not stock in an environment with increased levels
of air humidity. To prevent cable damage, plug or unplug the transducer by holding the cable jacket.
8.2.2 Precautions to take during Measurement
1. Once you place the transducer on the measuring object, the measuring symbol appears on
display (arrow down) to indicate the coupling action. As soon as the reading has stabilized,
you can lift the transducer from the measuring object.
2. Make sure to remove the transducer immediately after a reading has been taken successfully
as putting the transducer down again might cause erratic readings if big amounts of coupling
agent are placed on the measuring object.
3. Please note: a worn off transducer will lead to unstable and erratic readings and should be
replaced by a new one.
