QJ42E Resistance Bridge.
The QJ42E is a low cost portable dc double resistance bridge for low resistance measurement below 11Ω. This bridge can be used in the measurement of conductivity of metals, the d.c resistance of coils of generators and transformers, and the contact resistance of electric brushes, relays and switches.
