How Decade Boxes at IET Labs are Calibrated
IET Labs performs DC Resistance-Measure on decade resistors using any of the eight Fluke 8508A 8½ Digit Reference Multimeter owned by IET Labs, about ½ of the 8508As have option 001 for ratio transfer measurements using resistance standards. IET Labs added two Fluke 8588A 8½ Digit Reference Multimeters in 2021 to increase capacity.
Typical Bench and Test Instruments at IET LabsSee our New Certificate of Calibration with plots of measurement data and uncertainties, that is delivered with the 1433 and HARS-X Decade Resistors.
IET Labs uses the following Decision Rules when determining Pass/Fail for decade resistors.RDS (Root Difference Square) rule: A PASS is indicated if the MEASURED value ≤ Test limit where Test Limit is ≤ (Specification Limit^2 - Measurement Uncertainty^2)^0.5
This gives a PFA (Probability of False Accept) of < 0.6%.A PASS* indicates the MEASURED value is ≥Test Limits and
