A. Introduction

Congratulations: Thank you for purchasing TPI products. The SP565 is easy to use and built to last. It is backed by a 3-year limited warranty.

Product Description: The SP565 is a hot wire air velocity "Smart Probe". It connects to your mobile device and uses the TPI View App to display airflow & temperature readings. Reports can be saved and e-mailed or shared from the app.

B. Safety Considerations

• Never insert the sensor into hot air.
• Never allow a foreign object into the sensor cage. The sensor may be damaged.
• Do not expose the unit to damp environments for extended periods of time.

C. Specifications

The SP565 has been tested with the following standards and is in compliance with the council RED directive 2014/53/EU: EN 62479:2010, EN 61326-1:2013, EN 61010-1:2010, ETSI EN 301 489-17 V3.1.1(2017-02), ETSI EN 301 489-1 V2.1.1 (2017-02), ETSI EN 300 328 V2.2.0 (2017-11).

D. Instrument Overview

Using the Rotating Hotwire Probe

1. Take the hotwire probe and rotate it to the "UP" position. The back of the SP565 is marked to indicate the rotation direction for "UP" and "DOWN".
2. The hotwire probe can then be extended like an antenna. Pull up on the sensor housing to extend the probe.
3. Reverse these steps when storing the SP565.

E. Taking a Measurement

1. Download and install the TPI View App onto your mobile device. Run the App. The "Main Menu" screen will be displayed.
2. Press and hold the SP565 On/Off key down until it turns on. The LED indicator will initially be orange and blink. The SP565 will now be visible on the View app list. Press on the SP565 to connect. The LED indicator will turn Green and blink to indicate a link has been established. The App will display the model and ID number of the smart probe connected.
3. Rotate the SP565 probe into the "UP" position. Turn the cage cover so the sensor is exposed. The air velocity and temperature will be displayed.

App screenshots show the Main Menu, device connection list, and the live anemometer screen displaying Volume Flow, Velocity, and Temperature.

F. Performing Air Volume (Flow) Test

The View App allows you to perform air volume measurements by adjusting the Duct Details.

1. Adjust duct details to calculate Volume Flow.

App screenshot shows the Duct Details section with options for Rectangular/Round and input fields for Width and Height.

G. Air Volume Measurement - Traversing Horizontal Ducts

Preparing to Traverse a Rectangular Duct

To do a proper airflow measurement (CFM or CMM), you should perform traverse readings to obtain the true average airflow through the duct. It is recommended to take at least 12 points of measurement. There are two ways to perform this test using the SP565: Time Based Traverse and Spot Based Traverse. Time based is typically easier, but both are explained in the next sections.

1. Determine the easiest access to take your readings. Normally, it is best to enter from the side (Height) of the duct, as this requires drilling fewer holes. However, you may need to drill from the bottom (Width) of the duct. See diagram below.

Diagram shows a rectangular duct with drill points. One side is labeled "Drilling in the Height (least holes)" and the other "Drilling in the Width (most holes)". Arrows indicate "Choose one side to enter the duct" and "Ideal side to enter the duct".

H. Time Based Traverse - Rectangular Duct

1. Prepare the duct as outlined on page 5 and connect the SP565 to the App as outlined on page 3.
2. Set the App up to measure Air Flow and enter the duct type and size as outlined in section 4.
3. Insert the hotwire probe all the way into the duct at the first hole. Make sure the open area of the sensor is facing into the air flow. HINT: If you turn the probe, you will see the readings change up or down; the highest reading indicates the proper position.
4. Select "Timed Avg." in the app.
5. Once you've entered the correct Duct Details, tap the "Start Test" icon to begin the test process.
6. Slowly pull the probe towards the entrance point of the duct.

7. Diagram shows the probe being inserted into the duct and then slowly pulled back towards the entrance hole.

8. Stop at the last measurement point prior to pulling the probe out of the duct. Press the "Pause" icon to pause the recording.
9. Pull the probe out and insert it into the next test hole all the way into the duct.
10. Press the "Continue" icon to begin recording. Repeat these steps for all test holes.
11. When the duct has been completely traversed and prior to pulling the probe out of the last test hole, press the "Stop" icon.
12. Tap "Create Report" and save this to the required Job.

App screenshots show the 'Timed Avg.' screen, the 'Start Test' button, and the 'Pause' and 'Stop Test' icons.

I. Point Based Traverse - Horizontal Duct

1. Prepare the duct as outlined on page 5 and connect the SP565 to the App as outlined on page 3.
2. Set the App up to measure Air Flow and enter the duct type and size as outlined in section G.
3. Divide the duct into at least 12 equal boxes. Take the reading in the center of each box. Sample points should be no more than 4 inches apart from center to center. For larger duct sizes, add more sample points (boxes). Insert the hotwire probe all the way into the duct at the first hole, ensuring the sensor faces the air flow.
4. Select "Multi Avg." in the app.
5. Once you've entered the correct Duct Details, tap the "Start Test" icon to begin the test process.
6. Press the "Add To Average" icon to record the reading. The number of readings will increase by one (in brackets).
7. Slowly pull the probe towards the entrance point of the duct. Stop at each point and press the "Point" icon to record the reading.

8. Diagram shows a duct divided into a grid of boxes, with probe insertion points indicated by '+'. Arrows show the probe movement.

9. Pull the probe out and insert it into the next test hole all the way into the duct. Repeat this process until the duct is completely traversed.
10. When the duct has been completely traversed, tap the "Stop" icon to store the readings.
11. Tap "Create Report" and save this to the required Job.

App screenshots show the 'Multi Avg.' screen, the 'Start Test' button, the 'Add To Average' icon, and the 'Stop Test' icon.

J. Air Volume Measurement - Traversing Round Ducts

Traversing a round duct is very similar to traversing a horizontal duct. The preparation of the duct is slightly different. When traversing a round duct, the traverse must be made vertically and horizontally.

Preparing the Duct

You will need to drill 2 holes at 90 degrees to each other, similar to the drawing below.

Diagram shows a round duct with two holes drilled 90 degrees apart, with drills positioned to access the interior.

Time Based Traverse

1. Prepare the duct as outlined on page 12.
2. Traverse the duct both horizontally and vertically. Use the instructions on pages 8 through 10, substituting a round duct for the horizontal duct.

Diagrams illustrate vertical and horizontal traverses within a round duct.

Point Based Traverse

1. Prepare the duct as outlined on page 12.
2. Traverse the duct both horizontally and vertically. Use the instructions on pages 9 through 11, substituting a round duct for the horizontal duct.

Diagrams illustrate vertical and horizontal point-based traverses within a round duct.

K. Maintenance

1. Clean the surface of the instrument with a damp cloth.
2. Replace the three AAA batteries when the low battery indicator appears.
