It's been at its lowest position since the temperature was 25 ºC. We set the keystone to 488 µm and couldn't move it down more (8125, 8645).

- This fishing rod didn't seem to have any problems before but we haven't tried to use it at every temperature condition we've had.
Range: from -1000 µm to +1800 µm in the LVDT and from -746,000 to +746,000 steps in the stepper motor (3280).What was the temperature that day?
SR2
Top filter
Range: [ -1,700,000 , 1,500,000 ]
Stardard filter
Range: from -750 µm to 1000 µm in the LVDT and from 300,000 to 1,000,00 steps in the stepper motor (4431).
Bottom filter
Range: from -500 µm to 600 µm in the LVDT and from -550,000 to -250,000 (4430).
