Hi Friends,
I got a DS1102D Rigol Oscilloscope and I don't know what is going on with its rotary encoder. ( Its LJV Brand )
it looks like my problem like this problems in this video :
It happened once more than one year ago and I have opened the oscilloscope and disassembled the rotary encoder and cleaned it and it worked fine. This also happened again now and I have a little dusty lab. Is this due to dust ? or what ?
Also I have upgraded the firmware to the latest version from two years a go. could this the cause of the problem ?
if there any replacement for this rotary encoder, does anyone tried them for a long time ?
Thank You for your help.
