lamp is indicated by a popup window, showing the warm up time. Activation of the deuterium
lamp is indicated by the "UV" flag in the status bar of the device. The maximum service life of
the deuterium lamp is 1000 hours on average.
Adjusting the lamp change point controls the use of the UV lamp in the wavelength range
from 335 nm-345 nm. Enter the desired lamp change point on the numeric keypad and
confirm your entry with "OK". The settings will be saved upon exiting the menu.

NTU check
This function allows the detection of potentially interfering turbidity during the measurement
of light transmission in tube tests. The result of the turbidity measurement is stored together
with the actual measurement result.
Press the
icon to open a window for turning on this function. Mark the checkbox to turn
on the NTU check (see Figure 70). Define a warning limit and enter it via the numerical
keypad. If the specified warning limit is reached during a measurement, the measurement
result will be displayed in red as a warning. It is recommended that you pre-set the warning
limit to 10 NTU. The setting will be saved upon exiting the menu.
When activated, parallel to each measurement of a tube test for which the measurement of
the nephelometric turbidity is to be included, the NTU value (nephelometric turbidity units)
will be determined. The turbidity measurement is performed at a 90° angle at 860 nm. When
this option is activated, the measuring time for tube tests will be prolonged by a few seconds.
