1. Introduction
Thank you for purchasing TPI brand products. The TPI 575 Vane/Hotwire AirVelocity Meter is a state of the art,easy to use instrument designed to provid temperature and air velocity readings. The in strument is ruggedly constructed and comes with a 3 Year Guarantee.
This manual will guide you through the functions of the TPI 575 which will give you many years of reliable service.
Your TPI 575 Vane/Hotwire Air Velocity Meter comes complete with the following items as standard:
TPI 575 Instrument
Hotwire Probe Head
Vane Probe Head
Rubber Boot
Soft Carrying Case
Batteries
Instruction Manual
Your TPI 575 Digital Vane/Hotwire Thermometer has the follow­ing options available:
Serial Computer Interface RS232

9. If you selected a hot probe, pull down the sensor cover of the probe (so that air velocity sensor can be seen) and position the probe at desired location of measurement. The Probe should be positioned so that a white spot will face the winds
10. Read the velocity and temperature on the LCD
1 1 . It will take several minutes until the readings get stable
after the probe is positioned.
12. Press "HOLD" button to freeze the display after taking
a measurement is finished.
13. "DH" will be displayed on the LCD.
14. Press "HOLD" button again to return to normal operation.
Battery should be replaced when "LBT" is displayed at the top left of the screen.
Volume Measurements
To determine CFM (cubic feet per minute) in a duct, the area of the duct must first be measured (use the equations below). Then multiply an air velocity measurement by the area measurement to obtain CFM.
Area Equation for Square Ducts:
Height (H) Area(A)=Height(H) X Width(W)
Width(W)
Area Equation for Round Ducts:
Radius (R)Area (A) = pX R2 Where p = 3.14 R2 = (Radius x Radius)
CFM (ft3/min) =
Air Velocity (f/min) X Area (in square Inches)
144
Recording Data
If you want to record the reading changes, press "REC" button when the reading gets stable. Once activated the meter will begin recording.
1. The REC annunciator will be displayed. The meter will record

Operating Instructions
1. Select the Hot Wire probe or Vane probe for location of mea surement.
2. Connect the selected probe to themeter.
3. Push ON button to turnmeter on.
4 . Push HOT WIRE button or VANE button as per a selected probe.
5. Pressing the ˚C/˚F button will toggle between ˚C and ˚F.
6. Push UNIT button to select the desired display units of the air velocity.
7. The user can scroll through 5 units: m/s, km/s, ft/min, knots,mile/h.
8. "Zero setting : Do not follow normal velocity measurement procedure.On the sensing head, slide the sensor cover to the up positionure.On the sensing head, slide the cover to the up position to let the air velocity sensor isolated from the environment. Push the zero button to let the reading of air velocity show zero." will face the winds.

minimum, maximum and average temperatures.
2. To recall the data after recording, press "RCL" button.
3 . The "MAX", "MIN", "AVG" values will be recalled sequentially.
4. If you press "RCL" button, both temperature and wind
veloctity will be displayed at the same time on the LCD. The screen will display "MAX","MIN","AVG" sequentially.
5. Press "REC" button to return to normal operation.
The meter has auto power off feature on normal operation. ( 10 minutes) Auto power off is disabled on record mode.
RS232 Output
And then "RS-232" at the top right of the screen. This function prints the reading curreently being measurd in ASCII code. RS232 (p/n A500) cable is needed in order to view the readings on your computer.
