Hello all
In the process of trying to repair a U1604B scopemeter
Scope section was working but DMM section was not.
could switch between scope and DMM, but DMM would not display any readings Just linear bar graph and sometimes dc symbol,but blank reading. IN volts, ohms, diode etc. not 00000 just blank.
Wanted to know if anyone could direct me to schematics for this device.
Very complex duo board design, tough to reverse engineer.
Thanks for any input
