Sin cambio en la forma de onda de 1.V a 2.V
Posted: Wed Jun 05, 2019 12:23 pm
I have problems with the waveform of V / DIV = 1.V - V / DIV = 2.V, V / DIV = 2.V doubles the voltage,
I tried previous firmware version without favorable result
V / DIV = 2.V - SENSEL 3 = 0.06 V
V / DIV = 2 V - SENSEL 0 = 0.08 V
in V / DIV = 20.V the signal comes out down
V / DIV = 20.V - SENSEL 3 = 0.06 V
V / DIV = 20.V - SENSEL 2 = 0.07 V
V / DIV = 20.V - SENSEL 0 = 0.08 V
The remaining SENSEL of V / DIV = 2.V and V / DIV = 20.V are correct according to the SENSEL table
In the first image there is also a strange behavior in V / DIV = 10.V
Measures in GND
IMPUT = + 9.15
V + = + 8.32
AV + = + 6.74
V- = - 7.70
AV- = - 6.35
V1 = 0 V
V2 = 0V changes from (0V +) to (0V -) constantly
V3 = (- 0V) polymeter outputs the negative (-) constantly
V4 = + 1.40 V
V5 = Changing between (- 0.9V) and (- 1.00V)
V6 = + 5.45V
AIN = (GND = 0V) (DC = + 1.62V)
Plate version (C)
The DSO Shell is recently assembled, only used to calibrate
SMD components welded to the factory
Review with tin the components welded by me,
I checked values of resistors that mount, everything seems correct,
inspection of smd components that come from the factory, welds in good condition
Test voltages in (GND) correspond to what is established in the manual
Excuse me because I do not write in English, I hope that with the translator and the images they can understand and help me with this problem
My experience in electronics does not understand why the oscilloscope has this behavior
