The age of the heating element, the hours of use, and the
temperature at which the hot air gun is regularly used will affect
the life of the heating element and can cause fatigue. When a
heating element begins to fatigue, the heat that is transferred to
the blowing air from the heating element will begin to drop. If the
typical temperature used to desolder is not working as well as
when it was new, then it might be time to calibrate the unit.
Note: The heating elements are a consumable part for hot air guns.
There will come a time when the heating element stops working
due to age and/or too much deterioration. At this point, it will need
to be replaced and cannot be calibrated. Heating elements for this
unit can be found on our website (XTronicUSA.com).
CALIBRATION INSTRUCTIONS
Before measuring the temperature or calibrating the unit, ensure
all nozzles have been removed from the hot air gun. Once the
desired temperature has been set and the temperature of the unit
stabilizes, measure the heat of the hot air using
a high quality
and well calibrated hot air tester or an infrared thermometer.
If
using the infrared thermometer, aim it approximately three inches
away from the end of the hot air gun.
If the temperature shown on
the unit’s display does not reflect the temperature shown on the
tester, the unit can be calibrated.
1. Ensure the unit is off. Press and hold the Set button while
switching the unit on. This will put the unit into Calibration mode.
The left side of the screen will say “SEP” and the right side will say
“00” initially.
2. Then the left side will indicate the current programed temperature
and the right side will flash “00”, indicating the offset degrees. The
first time this is done it will display 00.
3.
Press the Air Flow ▲ or ▼ buttons to change the temperature
offset. This can be changed ± 99°.
4. When the proper temperature offset has been achieved, press the
Set button to save the setting.
5. When going back in to the calibration mode, the memory will show
how many degrees the unit has been offset with the past setting.
Setting it to 00 will reset it to the factory setting.
