Hi, I am trying to calibrate my DSO Shell using the TS Amp signals, but my readings still seem to be very off. I am using a power supply at 9.2V. The voltages at the test points are off. Especially V+ and V- which are reading closer to 7.79 and -7.79, and AV+/- is 6.88 and -6.38 The .1V TS shows a V...

Hi, Thanks for your response. I followed your instructions, but my readings still seem to be very off. The .1V TS shows a Vmax of 42 mV and a Vrms of 28mV. The 3.3V TS shows a Vmax of .93V and a Vrms of .6V. Any thoughts on what might be causing this? Also what function does the ground coupling swit...

Hi, I've been trying to calibrate the DSO Shell but I don't seem to get any signal when I run through the steps, with the coupling switch set to ground. I'm definitely getting a 1Khz signal from the test signal output, as I can see the square wave when the coupling switch is set to DC or AC. Also, I...
