The KB6011 comes with a built-in J321 Geiger-Muller tube, and ourdoes not provide the SBM20 Geiger-Muller tube or related products. However, the KB6011 has the SBM20 parameters built-in. If you have some hands-on skills, you can remove the back cover and install your own SBM20 Geiger-Muller tube. Then, in the device's menu options (press and hold the up and down buttons to enter the factory settings menu), set the sensor to SBM20 mode. Adjust the Cf calibration coefficient to a value between 1.0 and 1.15, which can be calibrated and set according to your standard radiation source or other equipment. Its default value is generally between 1.0 and 1.15. No other parameters need to be changed.

In addition, if you replace the Geiger-Muller tube, please ensure that the positive pole of the tube is on the screen side, meaning the upper area is the positive pole. Remove the tin-lead foil and wrap it around the SBM20 to provide some energy compensation, as our built-in conversion parameters are calibrated under the condition of having metal foil.

Another tip: If you press the ClearData button 20 times in a row, you will enter the factory test page. There is some Chinese text on this page, which can be ignored, as this page is generally only used during factory testing for workers. If you accidentally enter this page, don't worry. Just wait. If the device is damaged, it will indicate that it cannot pass the test. You can test it again. If it
