The 950038 Calibration Kit is used to calibrate and adjust the QuadTech/IET Labs 1910 and 1920 Series LCR Meters and consists of five calibration resistors, an open-circuit module, a short-circuit module and V-Cal Box.
The use of the 950038 Calibration Kit will bring the 1910 and 1920 LCR meters back to factory specification.
The R and Q values, at selected frequencies, are given on the enclosed Certificate of Calibration traceable to an SI.
The 950038 Calibration Kit can also be used for calibration of the IET/QuadTech 7000 Series LCR Meters, GenRad/IET 1689 and 1693 Digibridge RLC Meters.
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 20 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°..
