Testing Process: Excellent Results Across the Board

After cleaning and doing a visual inspection, we tested this Countess II by processing a slide. The slide triggered the camera and lights, which allowed us to focus, adjust brightness, and capture an image. After snapping the shot, the counting process initiated and returned appropriate results.

The firmware has been updated to the latest version as of February 4th, 2020.

This Countess II, manufactured on October 22, 2015, is in excellent condition overall.
