I believe 2 ppm/deg C is the specification. I am not even 100% sure of that, as I only have a Keysight part number 0699-3404 <0699-3404%20400> https://www.keysight.com/my/faces/partDetail.jspx?partNumber=0699-3404 If 400 k ohm was not such an obscure value I would have fitted a higher specification resistor, but there’s very little choice in 400 k ohm. There is a service note on this instrument that indicates the 400 k ohm resistor drifts, in some serial numbers. My instrument is missing the serial number, so I purchased a resistor just in case mine is fitted with a dodgy resistor.
