LDS1000 Controller for Laser Diode Sensors
For each of the parameters, a modification menu uses the following func-
tions:
(F2)Lower value.
(F3)Next highest value.
(F5)Save and Return to analog output mode.
List of parameters:
NOTE
When you exit analog output mode after modifying the integration
constant, the new value is also used to calculate the display of the
controller.
Scale factors that correspond to the combined choice of the gain and the
counter increment.
Example: using the Table.
The controller operates in manual mode with a Yincr value of 0.2 and a unit
given in arc-sec. The following values can therefore be read:
We can therefore expect to obtain the following analog values:
•With a gain of 1: OUTY = - 2.62 x25 = - 65.5 mV
OUTZ = 8.54 x25 = 213.5 mV
•With a gain of 5: OUTY = -2.62 x125 mV = - 327.5 mV
OUTZ = 8.54 x125 mV = 1067.5 mV
