Hi guys!
I found some minor software bugs.
For example, when you take a snapshot, a phrase saying "saved to files" appears. I accidentally deleted the file named 'files'.
And then when I took the screenshot it was not saved in the files section and I thought that if I try to open a new file and name it, the problem will be solved, but I could not name the file.
Then I inserted a flash drive and saved the file as files and copied it to the device. The problem was solved.
At the same time, the device has a listed measurement mode. Each time you take a new measurement, it saves the measurements in the list on the screen.
It works very stable when you set it to 10plc mode.
However, when you switch it to 100 plc mode, it does not write to the list.
in normal mode it is measuring in 100PLc mode without any problem.
Obviously these are minor issues. I believe simple bugs and problems will be fixed.
I tried contacting the factory and still got no response.
@killingtime contacted me and asked if there is a calibration menu directly from the front panel. (the customer distributor told him it was available and he(@killingtime) asked me for a check.)
And I have the firmware version (v1.2.42) installed. In the introduction manual it says that calibration can be done from the front panel. And I took a video for this. This firmware definitely does not have a front calibration menu.
there is no calibration menu on the front panel. I think the SCPI Command Reference is required for calibration.
And @killingtime gave me a fax suggestion, I will send a fax to the factory soon.He (@killingtime) helped me a lot, thank you for that.
I reviewed the post of a friend @ rsx90, and yes it is definitely the same as the 5492C model of the bk precision brand. And the site says it is $ 780.
https://www.bkprecision.com/products/multimeters#benchif you want a GPIB port the price is $ 970.
the hardware is exactly the same, the software interface is almost exactly the same, the color of the letters on the screen in the bk precision mark is white, and the color of the protective rubber is different.
I read that Tonghui company is the main producer of the bk precision brand. Brands always do this.
I would like to try and upgrade the BK precision 5492C model firmware on my device, but I could not find any upgraded firmware or software on the site.(I think they are still working on software and firmware.) It would be nice to try.
As a result, I expect many innovations to come with a new firmware.
And as a result the device is exactly the same device. I paid $ 457 for tonghui, bk precision is $ 780.
And I also bought a benchtop lcr meter from the tonghui brand. And this is definitely the same as bk precision, the only difference is the rubber color.
This device will be great if some firmware editing comes.
