Product Overview: The Monolithic Industries M117 & H12 Motor Bar to Bar Tester Complete is a specialized diagnostic instrument for testing DC motor armatures. It consists of two main components: the M117 mainframe base unit and the H12 armature head with fork probes. The system detects shorted or open bars in motor commutators by applying a variable-frequency AC signal (up to 5kHz) across armature segments and measuring impedance variations via an LED bar graph display. It operates in both manual and auto modes, with self-calibration capability. Common in motor repair shops, the unit tests armatures from small to large DC motors, helping identify winding faults before reassembly. The H12 head also includes a magnetic pole detector with bi-color LED indicator.

Units may experience issues such as failure to power on, erratic readings, or component-level faults involving capacitors and connectors. Defective solder joints and internal cable faults are among observed failure modes. Some units may exhibit calibration drift or fail self-test routines.
Repair Approach
Typical repairs may include replacement of defective components such as capacitors, connectors, and switches. Addressing solder joint integrity and replacing faulty wiring or cables are standard repair procedures. Preventative measures may include upgrading electrolytic capacitors and securing mechanical connections where applicable.
Testing & Quality
Following repair work, units are subject to functional testing and burn-in procedures to evaluate performance across applicable voltage and frequency ranges. Each repair is verified according to CSL quality control standards to confirm that observed issues have been addressed and system stability has been restored.
