WARNING!
Executing the calibration function (Factory Calibration Check)
With the FCC function you can check the temperature precision of
the soldering station and compensate for possible deviations. For
this purpose, the soldering-tip temperature must be measured with
an external temperature meter and a temperature measuring tip
assigned to the soldering tool.
Risk of burns
The soldering tool becomes hot during the calibration process.
There is a risk of burns from touching the tool.
Keep the hot soldering tool well away from flammable objects
and do not touch.
Changing calibration at 100 °C / 212 °F
1. Insert the temperature sensor (0.5 mm) of the external
temperature meter into the temperature measuring tip.
2. Select the menu item FCC in Menu 2.
3. Press the DOWN button.
Calibration point 100 °C / 212 °F is selected.
The soldering tip is now heated to 100 °C / 212 °F.
The control indicator flashes as soon as the temperature is
constant.
4. Compare the temperatures indicated by the meter with the
indications in the display.
5. Use the UP or DOWN button to set the difference between the
value indicated on the external meter and the value indicated on
the soldering station.
Maximum possible temperature adjustment ± 40 °C (± 72 °F).
Example:
Display 100 °C, external meter 98 °C: setting
Display 100 °C, external meter 102 °C: setting
Note Press button ┌ 2 ┐ to exit the menu item without changes (EXIT).
6. Press button┌ 1·2 ┐ (Set) to confirm the value.
The temperature deviation is now reset to 0 Calibration
at 100 °C / 212 °F is now concluded.
7. Exit Menu 2 with button ┌ 2 ┐.
