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
