DC Resistance Calibration - Resistance Calibration Standards and Service
IET Labs is a premier calibration laboratory that is accredited by A2LA for DC Resistance-Measure and DC Resistance-Generate.
We can calibrate most resistance standards, transfer standards or resistance decades from 0.01 Ω - 10 TΩ with uncertainties as good as 0.16 µΩ/Ω1.
Please contact our sales staff, by phone or online, who will be pleased to give you a quote for the calibration or repair of your equipment.
How IET Labs Calibrates Resistance Standards
IET Labs uses 2 main bridges for DC Resistance-Measure using transfer from standards that are calibrated traceable to the SI, through a National Metrology Institute (NIST, NRC, NPL etc.): 1.) The Measurements International 6000B Automatic High Resistance Ratio Bridge for measurement from 10 kΩ to 1 GΩ with a CMC1 down to 0.46 µΩ/Ω. 2.) The Measurements International 6010C Automatic Resistance Bridge for measurements from 0.1 Ω to 10 kΩ with a CMC1 down to 0.16 µΩ/Ω .
MI6010C and MI6000B Resistance Bridges at IET Labs
IET Labs also performs DC Resistance-Measure 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 standards.
Typical Bench and Test Instruments at IET Labs
Ratio transfer measurements, using the Fluke 8508A and a standard, are used for calibration of transfer standards such as the esi SR1010 and esi SR1030 and calibration of standards such as the IET Labs SRX Standard Resistors.
The table below shows the typical method used during calibration of some of our popular products.
