First run of 4wire measurement with DIY leads.Measurement setup:5700A set points are 10k 100k 1M 10M (OHM), respectively. External sense ON. For each set point it is measured 101 times, for each time the output is ON and OFF, this checks the relays. The instrument status is read to confirm the output settled status etc.3458A is reset once before measurement then the trigger is hold, the aper is set to 0.5s, after 5700A output settled there is about 2s wait time then a single trigger is taken and the data is read back to spreadsheet, after 101 data are complete the stdev and avg are calculated, the relative drift for 10k 100k and 1M is less than 1ppm while it is about 2ppm for 10M. ( The absolute accuracy is quite good even without ocomp or delay treatment on the DMM)So it is not the end, I'll check with different cabling and I think it'll be different results.If leave behind the issues arise from humidity, dust, relay contact etc.probably the cabling is important, I don't know what cabling Fluke use when they claim the issue.Attached is my DIY cabling under this measurement.
