I we increase the value 100 in table 0 for step 1, the limit for showing 1 faulty lamp will be
increased. If the value is changed from 100 to 120, the limit for 1 faulty lamp will be changed
from 176 to 186.

Calibration of the Uout measurement
The Uout measurement is done on the primary side of the Output Transformer, and multiplied
with the voltage ratio for this transformer. This means that we have to calibrate Uout when the
transformer tapping has been changed. The factory setting is for the output transformer in 100%
tapping.
The Key switch is turned to position ”Manual”
Press ”E”
Enter the code for User Menu
Press ”E”
Press
13 times to see ”Uout Calibration” in the display
Press
to get to the desired step for calibration (normally the 100% step)
The true output voltage value (see Note below) is entered by means of the 0 – 9 push-buttons
Press ”E”
Press
some seconds to get to the menu for ”Store data”
Press ”E”
Note:
The true output voltage for calibration in the 100% step can be found in many ways:
a.
The voltage can be measured by means of a high voltage measuring transformer and a true
RMS voltmeter
b.
The voltage on the primary side of the output transformer is measured with a true RMS
voltmeter, and the value multiplied with the actual voltage ratio of the output transformer
c.
The Uout is calibrate in the factory for 100% tapping. The output voltage is noted before
any tapping is done.
