无法使用E3632连续解除信号机

我有一台最近停止工作的E3632A电源。
我无法使用指轮调整电压或电流，但指轮调整将在显示限制模式下工作。当输出设置为开启时，“Unreg”信号器将自动启动。
电压始终使用DVM测量-0.523V。我可以使用IntuiLink与电源通信。
我可以使用IntuiLink调整电压和电流值，但输出始终测量-0.523V，尽管电源设置为。
显示屏将显示由IntuiLink设置的正确值，但输出始终使用DVM测量-0.524。有关如何纠正此问题的建议将不胜感激。谢谢提前。

  I have an E3632A Power Supply that has recently stop working.  I am not able to adjust voltage or current using the thumbwheel, but the thumbwheel adjustment will work in the display limit mode.
When the output is set to on, the 'Unreg' annunciator automatically comes on.  Voltage always measures -0.523V with a DVM.
I am able to communicate with the supply using IntuiLink.  I am able to adjust voltage and current values using IntuiLink but the output always measures -0.523V despite what the supply is set to.  The display will show the correct value set by IntuiLink, but the output always measures -0.524 using an DVM.

Any recommendations on how to correct this would be appreciated.
Thanks in advance.
