Executing the calibration function (Factory Calibration Check)
With the FCC function you can check the temperature precision of
the repair station and even out 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. The corresponding channel must be selected prior to
calibration.
Changing calibration at 100 °C / 210 °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 / 210 °F is selected.
The soldering tip is now heated to 100 °C / 210 °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 repair station.
Maximum possible temperature adjustment ± 40 °C (± 70 °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 the ┌1·2 ┐ (Set) button to confirm the value.
The temperature deviation is now reset to 0. Calibration at 100 °C
/ 210 °F is now concluded.
7. Exit Menu 2 with button ┌ 2 ┐.
Changing calibration at 450 °C / 840 °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 UP button.
Calibration point 450 °C / 840 °F is selected.
The soldering tip is now heated to 450 °C / 840 °F.
The control indicator (21) 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 repair station.
Maximum possible temperature adjustment ± 40 °C (± 70 °F).
Example:
Display 450 °C, external meter 448 °C: setting
Display 450 °C, external meter 452 °C: setting
Note Press button ┌ 2 ┐ to exit the menu item without changes (EXIT).
6. Press the ┌1·2 ┐ (Set) button to confirm the value.
The temperature deviation is now reset to 0. Calibration at 450 °C
/ 840 °F is now concluded.
7. Exit Menu 2 with button ┌ 2 ┐.
