The basic parameters of QJ83-1A portable digital DC single arm bridge are the same as those of QJ83-1. Powered by batteries and suitable for on-site use. The range is one level smaller than QJ83A (with a minimum resolution of 100 μ Ω starting from 2 Ω), which is more suitable for measuring medium and high resistance values. It is a unique digital bridge created by our factory, which is based on the bridge circuit and uses precision alloy wound resistors as the benchmark. It is an updated product of 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 resistances 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.
