Internal trigger
In the Dual/Single measurement screen, a trigger level based on the signal can be set as describe in the
chapter Internal Trigger.
4.11.1.3.1.2 Single Channel
The Single Channel measurement screen displays the numerical main measurement value recorded in the
activated measurement channel. The shown main measurement value is supported by a bar graph display
with range dependent scale, showing the utilization of the full-scale measuring range. The two markers in-
dicate the minimum and the maximum measured level. Reset them by touching the bar-graph or via the
side menu.
The channel header bar contains information about sensor type and temperature, actual measurement
range and specific warnings and information.
Below the channel header bar, the view includes up to six individually configurable small additional read-
ings. Touch the Zoom icon in the Side Menu to have the six readings disappear.
Switch between displayed channels by swiping the touch screen vertically, by pushing the channel button,
or by navigating to the CH1/CH2 indicator in the top bar using the rotary knob.
As in the Dual or Single Channel display, four Quick Set Buttons below the bar graph give the following op-
tions:
· Change the wavelength of measured light
· Perform a relative Measurement
· Perform Zeroing to set and subtract background
· Attenuation: Apply additional optical filter correction
Note Click on the screen icons in this manual to get to the explanations.
The measurement can be enlarged for best readability by omitting the extra displays. The zooming func-
tion is also available for the math view.
All setting are saved and restored after a reboot.
