Revision Level 000
This signal is scaled and linearized before being displayed and transmitted out as a 4-20mA or 0-
10VDC signal.
The AutoZero option detects and corrects any zero offset caused by large ambient temperature
changes. The Temperature Compensation option compensates the flow and velocity signal for density
changes caused by variations in the process air temperature.

1.4. Safety
1.4.1. Electrical Connections
Before any electrical connections are made, ensure the
POWER SWITCH
is in the
OFF
position.
1.4.2. Static Electricity
The circuit board contains components which are susceptible to damage caused by static electrical
discharge. Should it be necessary to remove the circuit board from the enclosure, appropriate
precautions must first be taken to ensure that the operator and the circuit board are at the same
electrical potential.
