For this purpose you should use a measuring unit with stable operation
up to a temperature of at least 350 °C.
In order to activate calibration mode, you must, during the switching-
on process, press key „T1”. „CAL 20” appears in the display together
with the soldering iron temperature, which should correspond to room
temperature. If the soldering iron is still warm, you must first allow it to
cool down to room temperature before proceeding further.
Having ensured that the soldering iron has cooled down to
approximately 20 °C, you must confirm this by pressing key „T1”.
Now key „T2” must be pressed. In the display „CAL 350” appears. The
LS 50 begins to heat up the soldering iron to 350 °C. If there is a
discrepancy between the display on the connected temperature
measuring unit and the LS 50 display, the latter can now be calibrated
by pressing the „+” / „-” keys. If both displays agree, you should now
press key „T3”. This concludes the calibration process. The new
calibration data is saved to the non-volatile memory on the LS 50.
12. Potential equalization
For soldering work on critical components the potential at the soldering
tip should be adapted to the circuit potential by operating via the
„Potential Equalization” socket. The voltage difference must be no more
than maximum 42 V.
13. Attaching a new soldering tip
The soldering tip can be replaced very easily and quickly thanks to
the soldering irons quick-action screw connector. If the soldering iron
is cold, the screw connector can be undone directly on the shank. The
sleeve can then be moved forward and withdrawn. The soldering tip is
now freely accessible.
The soldering iron must never be operated without a soldering tip attached.
This would damage the heating element and the temperature sensor.
The soldering iron is shipped with the following soldering tip attached:
0.8 mm soldering tip.
The following alternative soldering tips are available:
●
1.6 mm soldering tip
●
3.2 mm soldering tip

three seconds after the last time a key was pressed the LS 50 quits
programming mode automatically.

10. Switching over between
°C (Celsius) and °F (Fahrenheit)
If you prefer to have the temperature displayed in °F, the LS 50 must
first be switched to programming mode by pressing keys „T1”, „T2”
and „T3” together at the same time; (see Figure 4). Now in programming
mode the temperature displays can be switched over to °F by pressing
key „T3”. The arrow segment above this key disappears; (see Figure 9).
By pressing „T3” again the temperature displays can be switched back
to °C. After a period of three seconds after the last time a key was
pressed the LS 50 quits programming mode automatically.

11. Calibrating the temperature reading by software
The LS 50 is already adjusted in the production stage to a very high
level of precision. However if recalibration should prove necessary,
this can be performed using the integrated calibration mode.
Warning: As soon as calibration mode is activated, all previous
soldering iron data will be irrevocably deleted.
Before even starting the calibration process you must ensure that the
soldering iron temperature can be measured with sufficient accuracy.
