Note: The 6530 will accept only a resistor of approximately 100 MΩ with an
uncertainty better than
±
50ppm for setting the capacitor and
threshold error coefficients.
Table 8-6: Calibration Resistors
Note 1: Nominal Initial Tolerance is the maximum variation of resistance mean value as
adjusted initially at point of sale.
Note 2:
Calibrated at 23˚C, referred to the unit of resistance as maintained by National Research
Council (NRCC) or the National Institute of Standards and Technology (NIST) and expressed as
a total uncertainty with a coverage factor of k=2.
Note 3: Maximum Voltage Rating: 1000 DC V.
Note 4: The 100 MΩ resistor is strongly recommended to maintain a total uncertainty ratio of
4:1 for the 6530.
