2645A 4-Wire Resistance Measurement Specifications A-24.
Tables A-30 to A-32 provide 2645A specifications for the 4-wire resistance
measurement function. The 4-wire measurements use 2 input channels a decade
apart, e.g., channels 4 and 14.
Table A-30. 2645A 4-Wire Resistance Temperature Coefficient
Specification Characteristic
Temperature Coefficient Add 1/10th the 90 day specification per ºC
above 28ºC or below 18ºC.
Accuracy at -20ºC Multiply the -10°C to + 60°C accuracy
specification by 2. After 1 hour warm-up. For
accuracy between -10°C and -20°C, interpolate
linearly.
