TMT-PH300 IR Preheater

USER MANUAL

OPERATION - MODE 2

Operation - Mode "2"

When the preheater is set to Mode "2", the system uses a custom temperature/time 
profile to control temperature. The external temperature sensor "b" ("6b" in control 
diagram) is used to control the preheater temperature. The external temperature 
sensor "c" is used for additional monitoring. 

Note: In order to measure temperature 

correctly, kapton tape must be used to securely fix sensor B to the PCBA or 
component. If sensor B cannot accurately report temperature then the preheater 
temperature may run out of control.

1. Follow "Operation - Mode Selection" Instructions
2. Press the selection button ("2" in control diagram), the display will show "

run prof

"

3. Press the selection button. The digital display will show:

seg1

"

   

(2.a) lower digital display will show "

XXXt

" (xxx denotes time in seconds)

  Press the "▲" button or "▼" button to adjust the time (5 to 200 seconds)

Note: For safety, the temperature rise is limited to no more than 3C per second.

4. Press the selection button. The digital display will show: 
   

(1.a) upper digital display will show "

seg1

"

   

(2.a) lower digital display will show "

XXXC

" (xxx denotes temperature)

  Press the "▲" button or "▼" button to adjust the temperature (50C to 250C)

5. Repeat step 3 and 4 setting the time and temperature for segments 2 through 6 

(SEG2/3/4/5/6).

6. To start the preheating profile, repeatedly press the selection button until "

Prof

" is displayed, than press the "▲" button to start. A three second countdown 

will commence before the profile is initiated.

7. To see the current segment, the running time, or the temperature of the sensors, 

repeatedly press the selection button to switch between the different display modes.

8. After the profile finishes running, the display will show "

End

"

9. Press the press the "▲" button to save the profile and exit to profile adjustment 

mode.
