我有5个不同的6038A电源都做同样的事情，所以我很确定这些设备没有任何问题。
我无法在这5个电源中的任何一个上调整我的前面板数字读数电压表。 我假设你使用标有R24 Meter F.S的调节罐。 这意味着仪表满量程。 当我尝试调整这个R24电位器时，我可以看到前面板电压表或电流表没有变化。 是的，传感带被钩住用于本地传感。 遥控也做同样的事情，前面板与输出不一致。 读数只是少量的。 一个电源的读数低至200 mv，另一个电源读取电压为500mv，另一个电源读数接近1v，其他3个电源都足以满足手册前面的电表规格。 奇怪的是，在校准程序的手册中没有提到这种调整，或者在性能测试中没有提到它。 除了手册前面的一些规格以及三个范围以及前面板仪表的分辨率和精度之外，手册中没有提到前面板仪表。 如何调整这些电源上的这些前面板数字读数表？ 所有5个单位都有可能出现问题，因为它们都来自同一家公司，美国军方.... R24调整对所有5个供应都起作用，对调节器没有任何反应，同时监测 前面板显示...... 以上来自于谷歌翻译 以下为原文 I have 5 different 6038A power supplies that all do the same thing so I am pretty sure there is nothing wrong with these units. I cannot adjust my front panel digital readout voltmeter on any of these 5 power supplies. I am assuming that you use the adjustment pot labeled R24 Meter F.S. which means meter full scale. When I try to adjust this R24 pot i can see no changes in either the front panel voltmeter or the current meter. And yes the sensing strapping is hooked for local sensing. It also does the same thing with remote sensing, the front panel does not agree with the output. And the readings are only off by small amounts. One supply is reading low by 200 mv, another by 500mv, and another at almost 1v, the 3 others are all good enough to meet the meter specs in the front of the manual. The strange thing is that there is no mention of this adjustment in the manual for the calibration procedures or no mention of it in the performance tests. No where in the manual does it mention the front panel meters except for some specs in the front of the manual that gives three ranges and the resolution and accuracy of the front panel meters. How is one suppose to adjust these front panel digital readout meters on these power supplies? It is possible that there is something actually wrong with all 5 of the units as they all came from the same company, the US military.... The R24 adjustment acts the same on all 5 supplies, no reaction to the adjuster while monitoring the front panel displays...

你好micahcruz，作为澄清，R24仅用于校准非系统601xA和602xA电源。
以下信息适用于非系统耗材。 Russ的回复是针对系统供应的。 校准程序设置（60V）电流（磨碎器然后0安培）测试预期测试可变测试点测试顺序和调整结果----------- ------------- - ----------------- --------------------------------- --------------------- -------------仪表F / S仪表参考 A2J3引脚6（+）a。 连接测试点的DVM并打开0.5V + -50uVAdjust。 电压M（ - ）交流电。 湾 调整A2R24以获得结果中指定的电压范围。重新校准指南或修复后的电路板参考。 DesignatorA2控制板R24电压表满量程（F / S）校准的校准程序 以上来自于谷歌翻译 以下为原文 Hello micahcruz, As a clarification, R24 is used to calibrate only the non system 601xA and 602xA 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 以上来自于谷歌翻译 以下为原文 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 carl_panetta@agilent.com |

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。 以上来自于谷歌翻译 以下为原文 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. |
