8.3 Adjusting lamp voltage
Lamp voltage must be adjusted to the cable length in order to compensate
voltage loss in the cable. Too low voltage can lead to wrong measuring results.
Too high lamp voltage reduces the life span of the lamp module considerably.
1. Let the lamp module of the sensor operate for at least 3 minutes. During this
time the voltage at the lamp output clamps of the converter adjusts
depending on the load.
Caution!
The lamp voltage at the converter must not exceed 8.5 V DC or the system will
overheat!
2. Adjust the lamp voltage at the converter in the SYSTEM SETTINGS / LAMP
VOLTAGE menu (see chapter 9.4.3).
