  1. I forgot:

    the green display is colored :
    you can change to white or any color in the menu !

  2. I didn’t believe :
    This gadget is working !

    my problem was the rotary switch !
    I didn’t think about to press the shaft to initiate the circuit!
    You helped me by showing the newer device !
    Thank you

  3. I purchased a similar kit from Aliexpress as the one linked to is no longer available. I liked it because the LCD is color and very clear. I assembled it (it also has nice perspex looking plastic case) although not machined perfectly. SMD components are already fitted and after assembly its all working and very smart looking. Unfortunately the calibration menu does not work according to instructions it does read the shorting of the pins 1-3 and gives the result(as two lots of 0.0R) but never moves onto the next part where its supposed to ask you to remove the shorting link accross pins 1-3. The unit even checks and reports an Enhanced mode FET with a protection diode giving a graphical image a result for connection of G,D,S and order of the connection. A Vgs threshold voltage, an RDS on measurement in Ohms and of course the forward biassing result of the protection diode and some capacitance value also. So good but cant complete Calibration so the message is always showing up when not needed. The software version on this unit is 1.12k my email is micksbiz|character for mail|gmail.com if you want to message me i can send the linkl to purchase also if anyone has any ideas on the calibration issue or wants the pic of the Enhanced mode fet to see how good it is.
