Exchanging the measurement lamp
The measurement lamp has a high lifetime of several million measurements. How-
ever some day it can fail. A lamp failure will be displayed by a message window in the
device display. A defective lamp or lamp which is close to its final lifetime will not lead
to faulty measurements.
The lamp replacement kit includes the measurement lamp which is integrated in a
lamp socket with cables and plug and a special screwdriver type TORX T6. Replace-
ment of the lamp requires a clean workspace, a few technical skills and 15 minutes of
time. Of course, the lamp can be exchanged in the TECHKON service center as well.
1. Turn the device upside down
and place a soft cloth underneath
to avoid any scratches.
2. Remove the battery as
described on the previous page.
3. Release the four screws of the
lower casing with the TORX
screwdriver completely. They
can remain in the lower casing.
4. Now carefully separate the upper and lower casing and fold it apart.
Do not disconnect the cable connections.
5. Remove the lamp socket by unscrew-
ing two screws and pull the plug.
6. The lamp can be replaced by vertically
pulling it from the measurement head.
When putting in the new lamp, fit in the
plug correctly.

7. The assembly works accordingly to the
disassembly. Do not forget to connect the
grounding contact with one of the screws.
Do not pull the screws too tight, in order to
avoid damaging the threads.
