A self-contained calibration kit used to calibrate the 1910 and 1920. Includes a 4 BNC to BNC cable set (1 meter in length) for connection to the instrument. Consists of five resistors, a precision open and precision short. A calibration chart (NIST traceable) is provided with R & Q values for each resistor.
Nominal Values: R1: 95.3 kΩ ; R2: 5.97 kΩ , R3 374 Ω , R4 24.9 Ω; , R5 5.0 Ω
Accuracy: 0.1% of nominal value
Stability: Better than 25 ppm per year
Temperature Coefficient 2°C ppm
Calibration Accuracy: These resistors are compared with a precision of better than 40 ppm at DC . Measurement uncertainty of the nominal Q values are within 100 ppm at 1 KHz. All other R and Q values at other frequencies are mathematically calculated. All calibrations are made at 23° ± 2 C°..
