Agilent 6038A电源调整R24电位器时电压表和电流表没有变化

你好micahcruz，作为澄清，R24仅用于校准非系统601xA和602xA电源。

  Hello micahcruz,

As a clarification, R24 is used to calibrate only the non system 601xA and 602xA supplies.  The below information is for the non system supplies.  Russ' response below is for the system supplies.

你好micahcruz上一篇文章中的信息很难阅读。
它确实没有像我想的那样出来。请把你的电子邮件地址发给我，我会为你提供更好的消息.carl_panetta @ geilent.com

  Hello micahcruz
The infomation in the previous post is difficult to read. It really did not come out like I intended.
Please send me your email address and I will provide you with a better message

您好Micahcruz，这里有一些令人困惑的事情。
接口板/编程板在1991年左右发生了变化。如果你的单元比这更新，那么序列号为3025A-09316及以上。
较新的也现在将MY作为前两位数字。
这些单元不再使用R24，而6033A的工作台版本确实如此，但该单元现已废弃。
似乎金属板上的丝网仍然将R24称为仪表满量程调整，但它并不像您所发现的那样。
如果您参考从第16页开始的6038A维修手册，您将看到以下内容：远程回读Zero CalibrationUnder步骤g。
调节A8R51（READBACK ZERO），直到控制器上显示的值在：0和5mV（6033A）.0和15mV（6038A）之间切换.R51将前面板回读显示设置为零第17页您将看到以下内容：电压监视器和
远程回读满量程校准在步骤f。
调节A8R61（READBACK FS），直到控制器上显示的值在：20V和20.005V（6033A）.60V和60.015V（6038A）之间切换.R61设置前面板回读显示满刻度。我建议您完成
按照手册中的建议进行校准，但如果您知道其他一切都正确，那么您只需调整R61即可修复您的满量程回读编号。
此回读编号与通过接口返回的编号相同，因此更改编号会同时更改两者。

  Hello Micahcruz,

There are a couple of things that can be confusing here. There was a change to the interface board/ programming board that was made back around 1991. If your units are newer than this which would be serial number 3025A-09316 and above. The newer ones also now have MY as their first two digits. These units no longer use R24 there was a bench version of the 6033A that did but that unit has now been obsoleted. It appears that the silk screen on the sheet metal still refers to R24 as the Meter Full Scale adjustment but it is not as you have found. If you refer to the 6038A service manual starting on page 16 you will see the following;

Remote Readback Zero Calibration

Under step

g. Adjust A8R51 (READBACK ZERO) until the value displayed on the controller toggles between:
0 and 5mV (6033A).
0 and 15mV (6038A).

R51 sets the Front panel readback display to zero

On page 17 you will see the following;

Voltage Monitor and Remote Readback Full Scale Calibration

Under step

f. Adjust A8R61 (READBACK F.S.) until the value displayed on the controller toggles between:
20V and 20.005V (6033A).
60V and 60.015V (6038A).

R61 sets the Front panel readback display Full Scale.

I would recommend that you do the complete calibration as recommended in the manual but if you know everything else is correct then you could just adjust R61 to fix your full scale readback number. This readback number is the same one that is returned over the interface so changing one changes both.
