The QJ83 digital wide range DC single arm bridge is a unique digital bridge based on the bridge circuit and using precision alloy winding resistors as the reference. It is an updated product of the Wheatstone bridge. It has the characteristics of being as simple, fast, and eye-catching as a digital multimeter, while maintaining the accuracy, stability, and reliability of the Wheatstone bridge. It is the best choice for precision measurement of various DC resistors in industrial and mining enterprises, scientific research units, and metrology departments, as it is easy for users to use, does not require zero adjustment, does not need to match standards, and has fast testing.
Accuracy is superior to that achieved by an external galvanometer connected to a DC resistance bridge of the same level.
Simply connect the tested resistor and select the appropriate range, without the need for manual operation during the testing process.
The fast sampling time is 0.4 seconds, and stable data can generally be displayed within a few seconds.
Featuring a 200mm large digital display, the handwriting is clear and easy to read.
The stable main reference resistor is made of precision manganese copper alloy wire winding. Stability is better than 0.02%.
The reliable main components are imported original and specially selected for aging.
