Demonstration Mirror Description:
Question 1: What is the ghost mirror? Measure the internal resistance of the wire
Question 2: What do the measured values mean? No meaning, not absolute value, not relative value
Due to the different measurement principles and the influence of contact resistance, it is normal for the value to vary by ±500 characters per measurement.
Question 3: The Mirror Mirror measures 80, and the U3 measures 80 milliohms. Are they related? A: There is no dime relationship, the measurement principle is completely different
Question 4: The measurement result is plus or minus 500, is that not an entertainment measurement? A: Yes, entertainment measurement
Question 5: What interface do you use? Answer: USB-A molex male, TYPE-C: KR low resistance custom female, Micro: KR steel tongue, USB-A female: PAL custom high conductivity
Q6: What CPU is used? Answer: GD32E230 series, others sell you 288, here only 9.9
Q7: What is the measurement principle? Answer: True differential 8-wire Kelvin measurement, dual op amp differential sampling (voltage + current)
Question 8: Why is there a plus or minus 500 for the 8-wire measurement? Answer: SCM ADC sampling is entertainment
Q9: What should I do if I want to accurately measure the wire resistance? Answer: Measured with a commercial milliohmmeter (but does not eliminate the effect of contact resistance)
Question 10: Is there a second generation of Shining Mirror? Can contact resistance effects be eliminated? Answer: PPT
PS: 5V power supply, otherwise all burn
Key function: re-measure once
* Do not plug in when power on, after initialization, plug in the measurement wire
* What does the power-on number mean? Answer: The body is initialized, each mirror is different
* What is the meaning of the screen display? It doesn&x27;t make sense, it&x27;s all guesswork
The CC watch adopts an integrated injection molding process, and do not exceed the product parameters and specifications.
Once it is overused, it may cause permanent damage, and the malicious damage will be at your own risk.
Among them, C0Q uses a new domestic replacement chip, which has not been tested in large quantities
There may be unknown bugs, or unknown hidden problems, which are now in the public beta stage
At present, C0Q has arranged 100 old users to conduct public testing. The current price is expensive. It is not recommended to buy now.
The new version of C0+ uses TI&x27;s INA226 chip in the original original package, and it has no problem after long-term verification.
It is recommended that users who purchase CC pass-through meters give priority to C0+
Due to INA237, INA228 these 80V+ PD3.1 independent AD sampling chips, the market is completely out of stock, and TI&x27;s order cycle is very long
According to other friends, the price of a single AD chip has risen to 250 yuan a piece, and there is a price out of stock, and one less piece is sold.
At present, there is still a small amount of INA237 in stock for C2, one less is sold, and it is worthwhile to cherish it.
But C2 will not rise to more than 400, try to give everyone a discount, the last dozens of units, temporarily stop production after sold out~
CC pass-through table:
Without PD decoy trigger, without protocol deception detection, all are pure pass-through table (C0s, C2 are pure pass-through)
Support PD data pass-through, support magic modification protocol pass-through (24P pass-through)
Notice:
1. The shell is ultrasonically pressed, and there will be tiny boundaries, gaps, burrs, etc. at the connection. Please do not shoot if you mind.
Many of the promotional pictures on the product page are 3D renderings and there are subtle differences between the real objects and the real objects.
Due to frequent firmware updates, the actual product operation menu and display content will continue to change.
The quasi-product processing will go through multiple processes, and there will be scratches, machine oil marks, burrs on the keys, and defective keys, etc.
It is normal that the solder is not cleaned properly and does not affect normal use. Obsessive-compulsive, perfectionists do not shoot.
2. There are certain differences in the components, chips, interfaces, appearance, color deviation, character printing, packaging and other materials of the product due to the different batches of suppliers.
In the case of little change in performance, the actual product received by the user shall prevail without further notice
3. Express instructions: This store only sends ZTO Express, if urgent or ZTO can not contact customer service, it will be sent to SF Express.
