Safety
The Vaisala HUMICAP
®
Moisture and Temperature Transmitter Series
for Oil MMT310 is delivered to you tested for safety and approved as
shipped from the factory. Note the following precautions:
WARNING
Ground the product and verify outdoor installation grounding
periodically to minimize shock hazard.
CAUTION
Do not modify the unit. Improper modification can
damage the product
or lead to malfunction.
CAUTION
Do not touch the sensor plate.
CAUTION
In pressurized processes it is essential to tighten the supporting nuts and
screws very carefully to prevent loosening of the probe by the action of
pressure.
CAUTION
Take care not to damage the probe body. A damaged body makes the
probe less tight and may prevent it from going through the clasp nut.
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:
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench.
- When an ESD workbench is not available, ground yourself to the
equipment chassis with a wrist strap and a resistive connection cord.
- If you are unable to take either of the above precautions, touch a
conductive part of the equipment chassis with your other hand before
touching ESD sensitive components.
- Always hold component boards by the edges and avoid touching the
component contacts.
