Guys,
I have just received a DSO quad, and updated it to the latest FPGA, SYS and APP firmwares (APP 2.50).
I am having problems with calibrating the scope - I can enter calibration mode etc, connect the probe to ground, and the columns get filled in ok. Then when I connect my probe to a .250 V source as the instructions suggest, I am unable to change the value in the “voltage” column using the +/- keys. it stays on 0.000mv no matter what I do.
Any ideas?
Thanks a lot
Dan
