Range
- LVDT: [ -2500 , +4900 ] µm (7694).
- Stepper motor: [ -1,400,000 , +1,400,000 ] steps (7694).
- Temperature when measured:
Observations
- At 25 ºC it's possible to use the fishing rod to set the keystone at nominal position (8125).
- at 24.5 ºC or lower it's not (8645, 11465).

Standard Filter

Range
- LVDT: [ -700 , +700 ] µm (3558).
- Stepper motor: [ -870,000 to +835,000 ] steps (3558).
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).

Bottom filter

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).
