Hello, sorry for my bad English. RIGOL Puts certificates just because they can, not because the hardware complies to them IMO.
I have new RIGOL DP832, and first thing decided to check it. Upon boot you simply would discard the least significant digit in normal accuracy mode. But with High accuracy installed it seems to be way off from normal.
See attached LCD screen image, all 3 channels are set the same.
I connected digital multimeter Agilent U1252B that is more accurate than the RIGOL DP832, and all channels seem NORMAL.
Only LCD is showing wrong values for 1st channel.
Can I somehow correct it ? I would not want to sent the unit back, but I easily can because it's new out from the box I got today.
Thank you.
P.S. RIGOL has some quality issues, as up for a year there were no firmware updates, and calibration date on my is 2016-10-25, this is the same if I checked the calibration in the DP832 itself.
similar problem in year 2014
