FLUKE 720A Kelvin-Varley Divider

The Fluke 720A Kelvin-Varley Divider is a high-resolution primary ratio standard with absolute linearity of 0.1 ppm, temperature coefficient of linearity of 0.1 ppm/°C, and self-calibration capability. Specifications. Ratio Range: 0 to 1.0 (1 .0 input tap) and 0 to 1.1 (1 .1 input tap). Resolution: 0.1 ppm of input with seven decades. Absolute Linearity: (At calibration temperature and without the use of a correct chart) ±0.1 ppm of input at dial settings of 1.1 to 0.1, ±0.1 (10S) ^1/3 of input at dial settings (S) of 0.1 to 0. Temperature Coefficient of Linearity: ±0.1 ppm of inputl°C maximum at dial settings of 1.1 to 0.1. Short-Term Linearity Stability: Under typical conditions in a standards laboratory environment (temperature maintained within ±1 °C) and with an applied voltage of up to 100 V, stability of linearity is 0.1 ppm/30 days. Power Coefficient of Linearity: ±0.2 ppm of input/W max at dial settings of 1.1 to 0.1 ; ±0.2 (10S)^2 ppm of input/W max at dial settings (S) of 0.1 to 0. Maximum End Errors: Zero error at output low: 0.004 ppm of input. Zero error at input low: 0.05 ppm of input. Full-scale error: 0.05 ppm of input. Thermal Voltages: ±0.5 µV max. Maximum Input Voltage: 1000V on 1.0 input terminal, 1100 V on 1.1 input terminal. Input Resistance: 100 k-ohm ±0.005% at 1.0 input terminal at 25°C; 110 k-ohm ±0.005% at 1.1 input terminal at 25°C. Temperature Coefficient of Input Resistance: ±1 ppm per °C max

*This is a Web introductory price for one calibration of the FLUKE 720A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Available Gain
Available Gain is the ratio, at a specific frequency, of power available from the output to the power in from the source.

Decibel (dB)
A unit of measurement of power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Mismatch Uncertainty
Mismatch Uncertainty is caused by re-reflections between one device (the source) and the device that follows it (the load).

Pulse Power
Pulse Power, the energy transfer rate is averaged over the pulse width. Pulse width is considered to be the time between the 50 percent risetime/falltime amplitude points. Pulse power averages out any aberrations in the pulse envelope such as overshoot or ringing.
