6.3.7.2 Mastering
Mastering enables balancing the display and analog values to a reference part (master)
as single-point calibration.
The known value of the master (reference value) is entered via the menu points
Edit
program > Enter value for master
and saved under one of the new userspecific
names. Each measurement program can save its own master value.
i
Mastering and resetting are only possible together with the target.
In the measurement mode the master is placed in the beam and the key
ESC
is pressed
for three seconds. The display shows the value of the master. For resetting the
ESC
key
is again pressed during the measurement for three seconds. For this however a valid
measurement must be located in the display (not —,—).
After mastering an
R
for relative measurement is displayed in the
Full Display
below
the operating mode (e.g. DIA).
i
The master function is restricted to the display and the analog output. The digital
output is not affected.
Mastering is not available in the
Multi-segment
measurement program.
For the long-term saving of the single-point calibration, also after the supply voltage is
switched off, enter briefly into the menu
Main menu
and quit it again with
ESC
. You are
then requested to save. You can use the same user-specific name as used for entering
the master value.
For zero-setting after conclusion of mastering, the master value must be set again to
00.000.
With zero-setting or mastering via the external input by joining the connections Signal (5)
and GND (18) together there are two possibilities:
-
short pulse (0.5 to 3 s duration): Zero-setting (or mastering) when a valid measure-
ment is present and no master value is saved in the measurement program.
-
long pulse (3.0 to 6 s duration): Resetting of the master or zero-setting process.
Pulses which are shorter than 0.5 s or longer than 6 s are not processed.
The duration of the zero-setting (mastering) depends on the selected average.
With averaging over 128 values the process takes about 1 to 2 s and over 4096 values it
can take up to 1 minute. Settling to the final value can be observed on the analog output
and on the display.
6.3.7.3 Measurement Programs Segment and Multi-Segment
If the measurement program
Segment
(and
Multi-segment
) is selected, then you
can choose the edges between which the distance is to be measured. Whereas with
the normal Segment measurement program the distance of any two selectable edges is
found and output, with the
Multi-segment
measurement program the measurements
of up to four different segments are output consecutively. Here, the measurement output
is only possible via a digital interface. The analog output remains switched off at 0 V.
The measurement of the segments occurs simultaneously, but the output serially via the
digital interface.
i
In the
Multi-segment
measurement program the analog output remains switched
off at 0 V.
Up to 80 edges on the measurement object can be used to program the segments.
Use the command
SWITCH EDGE
(see page 43) to change between the segments.
