I can't support an MCU for which there is no publicly available datasheet (http:https://www.cachip.com.cn/Products_table/2.html).

[yo8saf]

so nothing can be done?

[Gissio]

No.

Actually, this looks like a copycat. Can you return the device and demand a "genuine" GC-01 with a J321 tube?

hi, There is MCU CA32F0602L3-19 (Turn off the device. Connect the charger. Press and hold the up arrow key. The processor model will be displayed.) The tube used is not j613/j614. The tube parameters are: Effective length: 60 mm Max. length: 88 mm Diameter: Ø 9.2 mm

Got same issue - same MCU, same tube. After closer inspection, there's plenty of evidence for such device being fake.

Some other signs include:

• instructions that omit Fnirsi logo (otherwise 1:1 copy of PDF from manufacturer)
• UI with minor differences (like lifetime vs runtime, which contradicts attached manual)
• starting value always 000.07 uSv/h
• ability to select languages other than English or Chinese (like Polish)
• label on back being 1:1 copy with QR code leading to proper manufacturer website, but with http:https://www.fnirel.cn/ printed below...
