(1)CH UPGRADE (Digital Oscilloscope)
a. Use the Type-C data cable with D+ and D- to connect the instrument and
 the computer in the off state
b. Wait for about 2s after booting.Observe whether there is a U disk named
 "CH BOOT" on the computer.If it does not exist, repeat steps A and B
c. Copy the firmware file starting with CH into the U disk.After the upgrade
 is complete, you will see an upgrade prompt at the bottom of the screen:
 Update complated
The instrument uses a USB analog U disk for firmware upgrade.The
simulated U disk cannot be used to save or transfer other data.For firmware
upgrade and charging only
Firmware comes in a variety of file formats.Different operating steps need to
be selected according to the situation
The computer system required for the upgrade is Windows 10 or above
External circuits must be powered down,Otherwise it will
damage the device
NOTE!
(3PWM Output: adjustable frequency and duty cycle, output from the top  
  MCX jack 【PWM】
(4)Zener Diode: Use the test seat K-A-A area for testing.See description in 【6.3
(5)DS18B20: Follow the on-screen instructions to insert the temperature  
  sensor into the test seat and measure
(6)DHT11: Follow the on-screen prompts to insert the temperature and    
  humidity sensor into the test seat to measure
(7)Autocal: Insert the three-pin short-circuit wire into the 1-2-3 jack of the  
  test socket.Press 【OK button to select Start.Press 【OK button again to  
  start calibration.During the calibration process, disconnect the short wire
  according to the prompt.When the progress bar reaches 100%,the    
  calibration of the current mode of the instrument is completed. No further
  action required
NOTE:1.The firmware starting with the prefix "CHD" is the firmware of the DSO     
   oscilloscope part.The firmware starting with the prefix "CHT" is the firmware of  
   the TC2 transistor part
   2.Only one firmware can be upgraded each time. If you need to upgrade     
   multiple firmwares, you need to repeat steps A, B, and C.
