D) Calibration - TOOLCRAFT ST-100HF Bedienungsanleitung

d) Calibration

Before starting the calibration process, check that the soldering tip has cooled down completely (to
room temperature). The temperature of the soldering tip at the start of the calibration process should be
+23 ±5 °C. In addition, ensure that the soldering iron is not exposed to a flow of air (e.g. fan or solder
fume extraction system), otherwise you will not be able to calibrate the soldering tip and an error message
("CALIBR. FAILED") will be displayed.
Ensure that the soldering iron is inserted into the soldering iron holder. The heating function will be acti-
vated when you start the calibration process. The target temperature is approximately 360 °C.
• Press button "2" when the main menu is displayed (see section 10. a). "CALIBR. MODE" will briefly appear on the
display.
"ENT.PASS 000" will be displayed.
• Use the three control buttons (2) to enter the password (the default password is "000"; if you have set another
password as described in section10. e), you will need to enter this password.
"1" = Decrease value
"2" = Choose input position
"3" = Increase value
• Hold down button "2" to confirm your entry. The password will flash three times. The soldering station will start the
heating process (indicated by the flashing red status LED) and "CNT DOWN" will be displayed. The display will
count down from 30 to 1 (30...29...28... 2...1).
As described at the beginning of this section, an error message will be displayed ("CALIBR. FAILED" or
"TIP MUST BE COLD") if the soldering iron is not completely cool. The temperature of the soldering tip at
the start of the calibration process should be +23 ±5 °C.
If the error message is displayed, switch off the soldering station and wait until the soldering iron is com-
pletely cool before starting the calibration process again.
• The countdown takes about 5 minutes, after which the soldering tip temperature will stabilize. "MEASURE TIP
TEMP" will be displayed.
Measure the soldering tip temperature with a suitable temperature measurement device (measure as close
as possible to the soldering tip). For best results and to prevent false measurements, use a surface probe
with a small measuring tip.
The soldering tip must be clean and well coated with tin.
• Briefly press the "2" button to end the heating process. "MEAS TEM 000" will be displayed.
• Use the three control buttons (2) to enter the measured temperature (permissible range: 320 °C to 400 °C).
"1" = Decrease value
"2" = Choose input position
"3" = Increase value
• Hold down button "2" to confirm your entry. The soldering tip temperature will flash three times and "CALIBR.
SUCCESS" will be displayed.
