• Enter the desired temperature setpoint (see chap. 5.3.1 Setpoint
Function (°)).
• Set the Tip Offset of the tip used (see chap. 5.3.4 Tip Offset Function (0)).
• In the menu item „Calibration", set the value to 0 by means of the
(+) and (-) keys.
• Return to the actual value display and wait until the displayed
temperature stabilises.
• Determine the temperature of the soldering tip using a calibrated gauge.
• Compare the two display values.
• Compute the temperature difference, with °T = T
• Set the computed temperature difference °T (with sign) in the menu
item „Calibration" by means of the (+) and (-) keys.
Note:
To avoid measurement errors, ensure calm air conditions.
6. Error Diagnosis and Troubleshooting

6.1 General Errors

If the soldering station does not operate as expected, check the
following items:
• Is main voltage present? (Correctly connect the mains lead to the
device and socket.)
• Is the fuse defective? Note that a defective fuse may also indicate a
deeper cause of error. Simply changing the fuse therefore generally
does not suffi ce.
• Is the soldering iron correctly connected to the supply unit?
If the soldering tip does not become hot after the above items have
been checked, you can use an ohmmeter to check the heat resistance
and the temperature sensor for conduction (Figure 10).
Continuity check for heating element.
The continuity resistance between measuring points 1 and 6 should
be between less than 6 Ω (at cool soldering iron). In the event of
interruption, the heating element is to be replaced (see left).
Continuity check for thermocouple
There should be less than 25 Ω continuity resistance between measuring
points 7 and 3. If the continuity resistence is higher, the tool must be repared.

6.2 Error Messages

The 1003A.E carries out an automatic error diagnosis. The result of a
diagnosis is outputted as an error code. The string ‚Err' then appears as the
fi rst three characters of the display. At the same time, the error code is
displayed as the fourth character. The error codes are listed in Table. Error
messages may also be confi rmed with the control buttons.

6.3 Other Errors

Other errors may also occur, indicating possible defects in the soldering tool.
These errors are:
• The station permanently displays only the room temperature. In this case, there
is a defect in the heating element or cable with thermocouple-controlled soldering
irons (Power tool, Tech tool).
• The station permanently displays an actual temperature that is too high.
This error can occur during operation of Chip tool. In this case, switch off the station
and replace the tool with an intact one.
6.4 Changing the Heating Element
Before changing a heating element, switch off the device at the mains
switch and pull the connecting plug of the soldering tool.
Allow the device to cool for a few minutes.
• Detach soldering iron from the station.
• Pull off cooled tip (pos. 1/fi g. 11) and tip mount (pos. 2/fi g. 11)
from the heating element. Pull off handle pad (pos. 4/fi g. 11).
• Unscrew handle mounting screw (pos. 5/fi g. 11).
• Pull off handle (pos. 6/fi g. 11).
• Disconnect soldering connection between the heating element (pos.
3/fi g. 11) and the connecting wire (pos. 7/fi g. 11).
• Change the heating element (pos. 3/fi g. 11) or connecting lead
(pos. 8/fi g. 11).
• Restore soldering connection between the heating element and the
connecting wire (fi g. 12).
• Assemble in reverse order.
