Cleaning
4.3 Cleaning
To clean the device, wipe it gently with a soft cloth moistened
with water or mild detergent.
IMPORTANT
Never use solvents such as benzene, alcohol, acetone,
ether, ketones, thinners or gasoline, as they can deform
and discolor the case.
CAUTION
• Measurements are degraded by dirt on the facing
surfaces of the sensor head, so keep the surfaces
clean by gently wiping with a soft cloth.
• Before cleaning the facing surfaces on the
sensor head, discharge any static electricity that
may have built up on your hands by touching a
nearby metal object. In this way you can ensure
that a high voltage, for example caused by static
electricity, will not be applied to the device.
Application of a high voltage to the device may
damage the internal Hall elements or circuitry.
• Clean the vents periodically to avoid blockage.
If a vents becomes clogged, the devices internal
cooling is impeded, and damage may result.
