I have a 2260B which is behaving very strangely suddenly. When I power it on, the front panel does not respond promptly and the display flashes some digits erratically.
On initial power up (after the "On" display clears) it shows
01
0.000
It does not respond to rotating either the Voltage or Current controls. It does not respond to pressing any keys.
I touch my hand to the top of the case and it will sometimes then start to "flash" what I have programmed for output voltage"
12.0 (intermittently) and 0.0
5.0
I then pressed the "Output" button and the unit responded as expected. Pressing the "Output" button again to shut off output also worked and the display now reads exactly what I would expect (no flashing).
0.01 v
0.00 A
Is this a symptom of a failing keypad or something? Any other ideas on what to consider?
Thx,
