Commands and Parameter LDM41A and LDM42A Manual
Page 30 ASTECH GmbH
8.7 DM – distance measurement
Input parameter SD, SE, SF, ST, OF
Output RS232/RS232, digital switching output, analog output
DM mode triggers a single measurement (single shot)
8.8 TP – internal temperature [°C]
TP queries the value of the inner LDM41A and LDM42A temperature.
Note: In tracking mode, the inner temperature may exceed the surrounding
temperature level by as much as 10 K.
8.9 SA – display/set average value [1..20]
SA allows you to calculate a floating average value from 1 to 20 measured
values. Calculation is based on this formula:
Average value:
Standard setting is 1 (no average).
8.10 SD – display/set display format [d/h/s}]
SD selects the output format of measured value data. There are three modes
available:
Table 6 : Output format
<SPACE>xxxxxx<CR><LF>
x=0...F
decimal with signal quality
xxx.xxx<SPACE>yyyyyy<CR><LF>
x=0…9; y=0…9
SD affects all commands that output a distance value.
An output value is calculated from a given measured distance value (in mm),
multiplied by the scale factor SF.
