As Nico says it could be a ribbon cable contact issue but FWIW the last section to the display is a mylar flat cable with embedded components which if faulty will require display replacement.

I've reached out to my "local" Canadian retailer .. awaiting response.

I have heard through word of mouth that Siglent themselves are not happy about this either.
I therefore sent the Siglent DC Load back.

Hi,

Hm-hm...
I can see two BNC jacks on the back, called I-Monitor and V-Monitor.
Usually you measure the voltage directly on the source, not on the sink.
I-Monitor could mean a voltage output across an internal shunt, very low values are expected and therefore a relative noisy signal.
All in all it won´t bother me, I would measure voltage/current in a different way.

nctnico:
Typically the I-monitor comes from the current shunt amplifier that provides a 0-10V output to represent the range of the DC-load. So this isn't a low-level signal. V-monitor the same; measured from the sense wires if you are using these. V-monitor is likely to be scaled down to a 0-10V level as well to allow easy interfacing to an analog signal acquisition system. Either way these signals should have a good enough accuracy. Just don't expect them to be floating in respect to the DUT.

Johnny B Good:
 JOOI, I checked the SDL1000X user guide and I can confirm that that is exactly the case (0-10v analogue output for both I and V monitor outputs).

 I have to admit that I've never tried using the monitor outputs on mine.

Just an update on this.  My "local" retailer is RCC Electronics.  They are sending me a new unit with a return shipping label for the faulty one.  Great service!!  If you're in Canada, they are the choice for Siglent equipment.
