Air Velocity
Setting the air velocity parameter is fairly simplistic; however, ensure no other outputs are enabled prior
to setup. (The EVM will display a pop-up message if more than one output is enabled. You will have to
disable all other auxiliary outputs before proceeding with air velocity setting.) When air velocity is
“enabled”, you can measure/log with the TSI Air Probe10 (optional accessory).
 Setting air velocity
1. From the setup screen, select Aux I/O and press Enter .
2. Press ▲ / ▼ Arrows to select Air Velocity and press Enter . To change the setting from either
enabled or disabled, press Enter .

3. Press ▲ / ▼ Arrows to change the setting.

NOTE: If you have either the digital-out or analog-out setting enabled, a pop-up message will
appear explaining to change the other settings before enabling air velocity.
4. Press On/Off/Esc twice to return to the start screen.
Analog-out
The analog-out channel provides a voltage reading that is proportional to the sensors output. The
analog-out channel can be configured to track any installed sensor. The example displayed in
Figure 3-12 shows the results of measuring with the thermometer from 0 to 60ºC reading from 0 to
5 volts.
