Подскажите пожалусто. После неудачной прошивки, приш ...

Привет, вы нашли решение проблемы режима GND? Я делаю то же самое, даже линия движется вниз! Вот видео

经过几天的琢磨使用2D72,我个人感觉是这样的,总体还可以,必定只是个几百块钱的东西(还没有一块好万用表贵)。它是以示波器为主,信号发生器和万用表作为附带综合在一起的,我一直在用汉泰产品,之前使用的是汉泰DSO1202B产品,感觉不错,就是个头有点大,拿着不方便,关键是没有信号源,所以再用汉泰2D72上手就特别快。首先谈一谈示波器,总体上手还是很容易,由于功能多,所以使用了很多综合键,出现一键多用,让人有点手慌脚乱,时不时记不住,会错按。它只能出现四组最常规的数值,电压最大值、最小值、频率、时长(时间)。有这几组可以推算出其它数值,如峰峰值就是最大值+最小值,如平均值就是(最大值+最小值)/2,作为维修有这些参数也足够用的了。本信号有2V输出,超过半导体通断门电压。信号发生器一般作为测试三极管和场管通断,向基极或控极提供振荡信号,或向设备提供信号也足够了,一般使用有效信号都在10K以内,高的基本上用不到,更何况它能提供70MB呢,这个功能很好,否则我不会购这块表。万用表功能有点不尽人意,我拿它与胜利86E作比较,电阻、电压、电流都不错,数字都非常接近,就是速度比胜利86E慢不少。它的垃圾点是电容档,测试的慢还非常不准,一点可靠性都没有。我从P法级到N法再到U法对很多电容进行测试,得出结果是这样的,1U法以下的电容很准确,1U法--10U法少了30%左右,11U法到100U法,就彻底崩溃,胡乱给一个数字。100U法以上就不工作了,连胡乱数字也不给了。不过说明书上也标定最大就是能测到100U法。这是个不靠谱的电容表,也许我的汉泰2D72是一个个例,也许是我中奖了。本人江苏泗洪,本表从闲鱼上购得590块钱包邮到家的,从内心来说感觉很是不错。对得起这个钱。

艾米同志!类似汉泰DSO和2000系列产品,严重依托软件才能工作的手持示波器,每解决一个问题或软件上的改进,都应该写一个说明,详细讲述新版本改进、增补或弥补那些不足。也好让我们具体使用者有一个选择,比如你们所提供的改进版本软件,我们根本就遇不到,那就可以选择不升级了,必定每次升级很麻繁还胆战心惊。艾米同志!你说呢?

Hello,

my name is Thorsten, I am from Germany, and I am new to this forum. ;)

Yesterday, I obtained my new 2D72 and so far, it works.

I would like to see some additional features for the DMM mode:

1. Possibility of measuring and displaying relative values.
2. Possibility of additionally displaying min and max values.
3. Possibility of fading out the connection scheme and instead fading in a bargraph.
4. Datalogger for logging and displaying measured values according to the picture shown within the quick guide.



Best regards,

Thorsten

Hello,

How can I transfer saved data from the oscilloscope to a PC, for example in the form of a .txt file? I need to analyze the data obtained outside.

Thanks for help
Best regards,

Zony

Hi again,

sometimes, the Hantek2xx2 software V.1.1.13 starts with a "read allset failed" message. How can I cope with this?

Anothter bug that I have recognized is that if I am hotplugging off the USB-A connector from my Surface Book 2, the software allways crashes.
