It delivers selectable DC test currents of 50A, 100A, 150A, and 200A, with the 100A and 200A settings meeting the requirements of China's Ministry of Power Standard DL/T845.4-2004 and verification procedure JJG1052-2009. The instrument achieves a measurement resolution of 0.01 micro-ohms and allows a custom test duration up to 599 seconds, exceeding the standard 60-second minimum maintenance time.
This device addresses the limitations of older QJ44-type double-arm DC bridges, which used milliamp-level test currents and could not reliably detect defects in conductor cross-sectional area. When measuring contact resistance in high-voltage switches, oil films and oxide layers between contacts can inflate readings. By using high-frequency switching power supplies and digital circuit technology, the 200P provides stable, accurate resistance values under load, effectively bypassing these surface-layer influences.
Primary buyers include electric power utilities, high-voltage switch manufacturers, and industrial maintenance departments requiring field verification of circuit breaker and switchgear loop resistance. The instrument features an ergonomic operator panel, a large-screen LCD for result display, and integrated functions for data storage, output printing, and time setting. Specific MOQ, lead time, and pricing terms should be confirmed directly with Wuhan GDMK Electric, as these are not detailed in the listing.

When sourcing the 200P Micro Ohmmeter from Wuhan GDMK Electric, first verify the instrument's compliance documentation. Request copies of test reports or certificates referencing the DL/T845.4-2004 and JJG1052-2009 standards to confirm the performance claims. For import into markets outside China, check if additional local certification (e.g., CE marking for Europe) is required and whether the supplier can provide it.
Clarify all logistics and trade terms directly with the supplier. The listing does not specify MOQ, lead time, or shipping terms. Confirm the total landed cost, including freight to your port and any import duties applicable to electrical test equipment in your country. Ask about the packaging method to ensure the sensitive instrument is protected during transit.
Upon receipt, perform a functional check. Verify that the instrument powers on, that the LCD displays correctly, and that it can initiate a test cycle using the 100A setting on a known reference resistor if possible. Review the user manual for calibration and maintenance schedules. Establish a direct line of communication with the supplier's technical support for any operational queries.
