Response: [:POPTP:ACT <NR3>]
Description: Queries the actual optical power, that is calculated from the position of
the potentiometer marked ADJ next to the LED P
LD
. This is the optical
power shown on the display. Unit: [W]
NOTE
This queries the optical power measured by the internal monitor diode that
is displayed on the 4 ½ digit display.
