Use the external couple to adjust the temperature
Statement: Statement: In this step, fault operating will cause temperature
deviation or even out of control, please be careful!
1 Set upper temperature/time/speed rate and so on (upper heater correction)
2 Suggest that do the correction on abandoned circuit, avoid damaging the circuit and
components on it
3 Carry out above process step (Three), install outer galvanic couple well, and center the
galvanic couple under the top head blow-dryer
4 Turn off the bottom heating process (Set the data relevant to bottom heating to be 0),
back to interface as image 5, click "Start" button, the machine begins to heat according
to data has been set Thus the outer measuring interface (image 17) will display the
current upper temperature (in red) and outer temperature (in light blue) as 2 curve lines
5 Red curve displays temperature measured by galvanic couple inside the upper thermal
fuse, light blue curve displays actual temperature measured by outer galvanic couple,
the smaller the deviation between the red curve and the light blue curve is, means the
nearer between the temperature of actually heating part and target temperature If it is
contrary, means the upper heating is not standard
6 If the deviation between these two curve lines is too large, proper adjustment to correct
is needed
7 Concrete method to adjust is below, because of impacted by system technology and
environment, the deviation is unavoidable, unless the deviation influenced soldering or
desoldering, non-professionals please do not operate as below!
A If outer curve (light blue) is lower than upper actual temperature curve (red), move in
the galvanic couple detector inside the upper blow-dryer
B If outer curve (light blue) is higher than actual upper temperature curve (red), move
out the galvanic couple detector inside the upper blow-dryer
C Adjustment range should not be too large, every time move it please control the range
within 1mm
D Repeat adjustment for several times
E In adjustment state, do not touch galvanic couple inside the upper blow-dryer by
anything, in order to avoid impacting accuracy of measuring temperature
F After adjustment, you should fix the detector, avoid the detector from impacting the
machine measuring temperature when shaking
