Safety
The SHM40 kit delivered to you has been tested approved as shipped
from the factory. Note the following precautions:
WARNING When drilling holes in concrete, wear respiratory protection to avoid
breathing concrete dust. If you are drilling through a floor coating, note
that the dust may also contain hazardous materials such as lead, asbestos
fibers, or crystalline silica. When cleaning the hole, avoid blowing dust
away from the hole – use a vacuum cleaner instead.
WARNING Contact with fresh (unhardened) concrete may cause irritation or burns
to the skin and eyes. Wear adequate protection and observe safe
workplace practices.
CAUTION Do not modify the unit. Improper modification can damage the product
or lead to malfunction.
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to
electronic circuits. Vaisala products are adequately protected against
ESD for their intended use. It is possible to damage the product,
however, by delivering electrostatic discharges when touching,
removing, or inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages yourself, avoid
touching exposed contacts on the probe or the meter.
