- oPEn displays when the probe is not connected.
- Only back light key and power key work in this condition.
- Connect the Hot wire probe and display ‘H—d’.
Main screen: Inverse counting for 5 sec > Hot wire warming up on Hot wire probeH — d : Hotwire warming up Delay - Vane Probe connect > Display the air velocity without delay.
- Measure the air velocity.
UNIT setting
- Push the UNIT key.
- SET display. Display the Air velocity unit. Change the unit to push the UP, Down key.
- Push the Right key when the right unit blinks. CMM, CFM blink next and change to push the Up, Down key.
- Push the Right key when the right unit blinks. The temperature unit blink next and change to push the Up, Down key.
- Push the Right key when the right unit blinks. The area unit blink next and change to push the Up, Dow n key.
- Push the Enter key and set the unit.
Record
- Push the REC key.
- SET display. Choose Point or Time to push the Up / Down key.
- Choose Time , Point to push the Enter key.
- Time: Push the Enter key and capture the measurement value at 1 sec interval. (Start / Stop the capture with the Enter key.)
- Point: Capture with each Enter key.
- Record mode: MAX >MIN>AVG with REC key.
- Record data is cleared when your push the Left key on Record Stop.
- Transfer from Record mode to General measurement mode to push the REC key more than 2 sec.
DUCT setting
- Push the DUCT key.
- Choose Free Area , Rectangle , Circular with the Up / Down key.
- Set to push the Enter Key.
- Choose the value with Up / Down , Left / Right key.
- Set to push the Enter key.
** Push the Enter key on general air velocity measurement mode and it changes to air volume measurement.
- Duct size max value
- Unit cm : 9999
- Unit m : 99.99
- Unit ft : 99.99
- Unit in : 999.9
** The max value is saved if the unit changed value is higher than max value.
Memory ( 0 ~ 299 )
Measure the air velocity and air volume on general mode or Record mode.
- Push the MEM key.
– CaptureTpi580 and Memory mode displays. (Data save mode) - Choose the address with the arrow key ( left, right, up, down ).
- Push the Enter key.
– Tpi580 saves the captured data to the selected address.
– End the Memory mode. Now it is measurement mode.
When you save the measurement value on Record mode, it can be saved on Stop and saves the average value.
* Memory All Clear *
Push the MEM key more than 2 sec on Memory mode and Clear starts.
When Clear is done, the display changes to general measurement mode.
* Escape / Cancel *
The work is done with the UNIT key on Memory mode and Recall mode and now it is general measurement mode.
** Memory mode is not working on “OPEN”.
** It can’t recall when you recall the address without saved data.
RECALL ( 0 ~ 299 )
- Push the RCL key.
- Choose the Recall address with the left, right, up, down key.
- Push the Enter key.
- Display the saved value.
– Recall: “HOLD” and “ REC” display.
– Velocity / Volume display with Enter key.
– You can check the Duct size and type with Bluetooth.
