AD-1272 Advanced Thermal Dispersion Probe Airflow Measuring System Technical Bulletin

After 5 seconds, the display indicates the number of active probes and sensors. This example indicates one active
probe and four total sensors.
Note:
When the Primary Transmitter with Display is located remotely, the AD-1272 count the Primary Transmitter
as an additional probe. This will cause the number of probes to be shown as one greater than the number
of ancillary probes.
After another 5 seconds, the display indicates that the unit is warming up.
Normal Operation
The normal operation screens display the average temperature and average velocity or volume in the units
selected.
When the display is configured for the International System of Units (SI), the display shows the temperature in
Celsius and the average velocity in meters per second or the volume as liters per minute. See Table 3 for the
available units.
When the display is configured for Imperial, the display shows the temperature in Fahrenheit and the average
velocity in Actual Cubic Feet per Minute. See Table 3 for the available units.
Note:
An asterisk (*) appears on the top left corner of the display if the number of sensors has changed during
normal operation mode.
