This Keithley 2306 has been fully tested and is in very good condition. The display is good and bright, even though my photos may look like the display is dim in some photos.It was just the camera and angle of shot.  NIST calibration was performed by an external lab prior in August 2016 with a 2 year cal cycle. Call Keith at 209-386-7544 for details.

Testing portable, battery-operated devices under real-word conditions demands a DC power supply that can simulate a battery’s performance over a wide range of conditions. Series 2300 battery simulating power supplies can simulate both a battery's output resistance and output voltage response. The dual-channel versions of these power supplies provide one channel to act like a battery and sink current for simulating a discharged rechargeable battery; the other channel supplies voltage for testing a device’s charge control circuitry.
