display
Channel 1 4 ½- Digital LED display with 40 Segment LED bar graph X, R, X-noise, Aux 1 or Aux 2. The
display can also be any of these quantities divided by Aux 1 or Aux 2.
Channel 2 (SR830) 4 ½- Digital LED display with 40 Segment LED bar graph Y, θ, Y-noise, Aux 3 or
Aux 4. The display can also be any of these quantities divided by Aux 3 or Aux 4.
Compensation x, y, R can be offset up to ± 105% of full scale
Magnification x, y, R can be expanded by 10 × or 100 ×.
