K. Utilizing the Solder Iron Digital Temperature Calibration
By default, the system is properly calibrated but for some cases
when a little adjustment of the soldering iron temperature is required
the following procedure can be done.
1. Turn on the soldering iron function.
2. Set to appropriate temperature you want to calibrate. Place the tip
of the soldering iron on an external temperature sensor.
3. The readings on the external temperature sensor should be more
or less equal to the displayed temperature.
4. Write down the displayed actual temperature of the soldering iron
and the displayed temperature readout from the external
temperature sensor. If there is a large discrepancy in the
temperature reading we can re-calibrate the temperature setting.
5. Follow System Setting
selection menu to Set 005, then turn the
temperature knob to off position.
6. If successful the display would show " 0FSt 017" indicating
soldering iron digital calibration is being set.
7. Compare
temperature readings. If external temperature readings is higher
that the act temperature display then get the difference and
enter a negative value by adjusting the air flow adjustment knob
"A2", Calibration value is adjustable from –70 to 70 degrees with
"000" signifying no offset.
8. Save the selected calibration settings and exit from the calibration
menu by turning the soldering iron set temperature knob to off
position.
9. Enter soldering iron function and set to desire temperature, check
if additional calibration is needed. If additional calibration is
needed repeat steps 1to 8 and each time adjusting the calibration
value slightly higher or lower based on the previously entered
