ASTECH GmbH Page 39
For example, if ASDT has been parameterized, the LDM41A and LDM42A will
begin with distance tracking on turning on power.
8.26 OF – display/set distance offset
With the help of OF (offset) the user may define a zero-point for his/her
application. For details on the position of the module’s zero-point, refer to
section 4.
OF must be selected so it is properly matched to the currently valid scale
factor setting (SF).
OF may also take on negative values. Standard setting: 0
8.27 SO – set current distance to offset
SO performs a distance measurement and saves the measured reading as an
offset value with inverted mathematical sign (OF).
8.28 LO – Laser on
LO turns the Laser on. This function can be used for orientation or functional
testing of the LDM41A and LDM42A. After the command LO it’s necessary to
send LF! Don’t use LO because this. Please use instead of LO the command DT
to turn the Laser on.
8.29 LF – laser off
LF turns the Laser off.
8.30 PA – display settings
