STARTUP INSTRUCTIONS:
1. Verify that the sensor probe is located where they meet EBTRON published installation guides.
2. Verify that the probe is properly installed with the airflow arrow pointing in the direction of airflow.
 Improperly installed probes will compromise the installed accuracy of the device and degrade system
performance.
3. Verify that the transmitter is installed and wired in accordance with the HTA104-T Wiring Guide
provided with the transmitter and power is provided to the transmitter.
4. Make sure the ductwork is clean and free of debris prior to fan startup.
5. Move the power switch to the “ON” position. Power-up faults, if detected, are displayed on the LCD.
If any power up faults are detected, resolve all conflicts or contact EBTRON customer service at
1-800-232-8766 before proceeding..
 If extension cables have been added, the extension cable length must be entered into the transmitter.
Refer to the Operations and Maintenance Manual for more information.
6. The transmitter is fully functional as a factory calibrated airflow and temperature measurement device
in I-P units (ft, FPM, CFM °F). Airflow (CFM) and temperature (°F) are displayed on the LCD.
 If SI units are required, refer to the Operations and Maintenance Manual.
 The factory default airflow output is set to actual airflow (FPM, CFM). If standard (mass) airflow
(SFPM, SCFM) is required, refer to the Operations and Maintenance Manual.
7. Verify that the area on the hang-tag matches the actual area of the duct or opening where the probes
are located (less any internal insulation). If the area is different, modify the area parameter stored in
the transmitter and use the correct area for any external conversion calculations from FPM to CFM.
 Failure to use the correct area will result in volumetric airflow (CFM) measurement error and degrade
