The transmitter delivered to you has been tested and approved as shipped
from the factory. Note the following precautions:
Connect only de-energized wires.
If you connect more than one transmitter to a single 24 VAC transformer,
always connect the phase (~) to the +Vs connector in each transmitter.
The trimmers only turn 135 degrees each way, less than half a rotation.
Do not force the trimmer past the stopping point.
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:
- When installing the transmitter, do not touch exposed contacts on the
component board.
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench.
- Always hold component boards by the edges and avoid touching the
component contacts.
