10.4 Cleaning the touchscreen and other components
Safety
WARNING
Danger of explosions due to static discharge
Cleaning the plastic surfaces, in particular the
touchscreen, using a
dry
cloth can result in static
discharge. Any sparks could ignite a potentially
explosive atmosphere.
For this reason:
– Always clean plastic surfaces with a
damp
cloth.
−
Do not clean the touchscreen window with aggressive solvents
or scouring agents and do not clean with instrument air or
steam cleaners. The touchscreen is a part of the control box
and therefore fulfills a protective function and must not be
damaged.
−
To clean the touchscreen, only use water and detergent or
monitor-cleaning foam.
Cleaning the touchscreen
•
Switch off the device.
When touching the touchscreen, functions can be inadvertently
triggered.
•
Moisten the cleaning cloth with water.
•
Apply detergent to the cleaning cloth and not to the
touchscreen.
•
Clean the touchscreen with the cleaning cloth.
When touchscreen cleaning has been completed,
the device can be switched on again.
Cleaning other components
Do not clean painted or plastic surfaces and seals with aggressive
solvents, scouring agents, high pressure cleaners or steam
cleaners.
Only use cleaning cloths and soap suds for cleaning.
This applies in particular to the control box and the measuring unit
box.
Make sure that no moisture can penetrate voltage-conducting
parts.
