We moved our network analyzer from on plant to another. When I reconnected it and started it up after displaying that the unit was initializing I receive a red " Caution: Power Supply Shutdown" message and the display doesn't work. The LED on the back of the unit is green and the power is set correctly at 110VAC. All the LED's on the front of the analyzer are working. When I checked the manual all it told me was this was an error code 22. The unit has been unplugged and in storage for about six weeks.
