5.1 Equipment required for the individual settings
Note:
The device is fully adjusted and tested by the manufacturer. Readjustments should be
performed by qualified personnel only. Opening the equipment or performance of any repairs
or modifications of the equipment by unauthorized persons shall relieve KARL STORZ GmbH
& Co. KG of any liability for its performance. Any such opening, repair, or modification
performed during the warranty period shall void all warranty.
Lamp current is the only recommended adjustment and may be performed when a new lamp
is installed, but is normally necessary only after repairing the power supply.
5.2 Test instruments required for the individual
adjustment procedures
– Digital voltmeter (DVM)
– Small flat blade screwdriver
– Torx screwdriver with assorted bits
– Current probe
5.3 Testing and adjusting the lamp current (up to serial
no. LF0611982)
a. Disconnect the power cord from the light source.
b. Remove the outer cover by sliding the interlock slide to the right, removing the four screws on the
bottom of the case, and sliding the cover back.
c. Lift the lamp insulator and fold it back.
d. Reconnect the power cord and turn the device power on.
Caution: Do not look into the lamp or light cable. Do not allow light from either the light
source or the light-cable to shine directly on hands or other areas of the body;
burns may occur.
Caution: Lamps are high pressure vessels and must be handled with care. When
handling the lamp wear safety glasses and face shields to protect the face
and gloves to prevent skin oil transfer. Never touch the porcelain insulator on
the lamp with bare hands. When working with an operating lamp, wear eye
and face protection to prevent blindness or UV damage.
Caution: Connect the voltmeter only when the lamp is already started; otherwise, the
high-voltage starting pulse will damage or destroy the voltmeter. Do not
restart the device when making measurements.
e. Connect the DVM across the lamp. Measure and record the lamp voltage.
f. Lamp power (the product of current and voltage) should be around 300 W. Set the current probe to
10 mV/A, place current probe on lamp return (-) wire and adjust the lamp current to 0.19 V (
앐
0.01) /
19 A or to a value that would result the 300 W power requirement. The current adjustment
potentiometer is RV2 on the power supply.
g. Remove the DVM from the circuit and turn off the power.
h. Reassemble in reverse order of disassembly.

Caution: Always unplug the device from the power supply before carrying out any
repairs on it!
After servicing, a safety test or the leakage current and protective ground
resistance measurements according to IEC 62353, IEC / UL 60601-1, CAN /
CSA C22.2 NO 601.1, whichever may apply, are to be carried out.
To prevent damage to the components caused by the build-up of electrostatic
charges, we recommend that you connect yourself to ground via the
wristband throughout servicing.
