Product IntroductionProduct Introduction
The DQJ-1 DC single bridge calibration device is produced in accordance with the JJG982-2003 DC Resistance Box Calibration Regulations and JJG125-2004 DC Bridge Calibration Regulations, and is used for the overall calibration of portable single bridges. There are ten ten ten pin resistor pads with a measurement upper limit of 11 M Ω and a minimum step voltage of 1 m Ω, which can cover all measurement limits of portable single bridges and have the minimum resolution requirement for verifying the bridge. This device has different accuracies depending on the range of the bridge, so the ten pin resistor plate has different accuracies.
