Hi,

Do you find it's difficult to change the position the slide switch with the case?

Nobody can answer me!!!

Hi,

I use this for testing crystal and like frequency Counter.
You can find on Aliexpress.

Hi,

Does a member can tell me with a multimeter, what is the resistor each Side of R26 and the Gnd? I suspect my output TESTSIG.

Thanks

Hi,
I must replace a ceramic capacitor.
Do you can tell me what's the voltage maximum?

Thanks

Hi,

I don't understand, my oscillo give me a wrong measure on battery 9V. But it's ok with an adapter 9V.

Good luck

Hi, My voltages are: V+ = 8.61V V- = =9.65V AV+ = 4.9V AV- = -4.97V +5 = 4.93V +3.3 = 3.29V TP2 = 3.29V My problem is: The voltage at output test is very very low millivolts (see picture). It's impossible to calibrate the oscillo by this input. The resistor between the output pin 17 (TESTSIG) of MCU...
