Dear amy

I understand that it is impossible to execute all the Wishlist, but the display in the measurement of the amplitude value was a more correct decision. If we add to it the root-mean-square value of the amplitude would be generally wonderful.
And the minimum and maximum is needed mainly for measurements in the car and in everyday tasks of repairing radio equipment only interferes. And you can also make a long press of the menu button to close the status bar.

把二极管测试提高到2-3v，这个硬件就完全不一样了。

如果必须这个功能，您可以考虑DSO1000B系列，这个可以点亮发光二极管。

二极管只能测试1V导通电压，发光二极管导通电压大于1.6V了，点不亮。
测电阻和刷新太慢，请先参照下面的帖 ...

有什么方法请告知，把二极管测试提高到2-3v。我接受改装，这个功能在维修工作中占据着很重要的位置。
还有下面的问题：
1：就是设备连接到上位机以后，拔下来，示波器会初始化为出厂设置。
2：示波器的波形，测试晶振波形时，不是很圆滑的正弦曲线，感觉有点变形，且可以看到频率在一直的刷新。一般示波器测试12m，基本上就是12.或者多一点点，很稳定的数字，这个示波器就是11m--12多，这样不停刷新。
最近没怎么使用，忙完这段时间，深入使用后，我通过微信发送售后，总体来讲此款示波器做的是比较符合需求的，开关机速度，人性化，上位机，功能等。需求做的没什么问题，很符合使用需求。只是细节方面希望更提高一点。

关于bug的反馈：
二极管档测量LED灯，灯不亮，不显示导通电压。二极管，三极管测量很鸡肋。
万用表功能经常 ...

万用表功能经常处在假死状态，比如测量电阻时，偶尔用手碰一下，或者立马换一个电阻，就会像是死机一样没反应，需重新按键激活。
示波功能：采集刷新太慢，表现为：测试晶振时，正玄波不圆润，变形，同时频率显示不停的变化幅度太大。

New bug found!

Cant measure more then 399V DC or AC in DMM mode.

Sorry, there is a mistake in the manual about the drop voltage in diode mode. It should be 1V

399V problem is solved. Resistance measurement was with error.
There was burned resistor R15 (1k).
It was a little brownish, and was changed to new one.

New bug found!

Drop voltage in diode mode maximum 0.999 V.

Fill it be fixed? And when? What about other my questions?

AxGxP

Done. Verification OK.
Seems the calibration freezing been fixed, thank you.

But something wrong, firmware version didn't changed. Is it OK?

"Menu">"Sys Info"
SOFT : 2018120601
PCB: 0000000001
FPGA: V02

Can you tell me something about my wishes, will you change it, how fast?
I need more information to make nice video overview about it (in russian).

May be you need some help with programming?
Contact me freely by email.

About the calibration problem, please refer to the following post and download the latest firmware to update.

About the "DC mA" problem, please connect two red and black pens to the mA test ends and shorten them, what is the current value displayed?
