It delivers a DC test current of 100A, which meets the requirements of Chinese power industry standards DL/T845.4-2004 and JJG1052-2009. The instrument achieves a resolution of 0.01µΩ, enabling precise detection of resistance changes caused by oxide layers or reduced conductor cross-sections.
Conventional double-arm DC bridges (such as the QJ44 type) typically operate at milliamp-level test currents, which are insufficient to overcome the influence of oil films and oxide layers on switch contacts. The 100P addresses this by maintaining a sustained 100A current for a configurable duration, up to 599 seconds, well beyond the 60-second minimum specified in national standards. It also offers a 50A measurement range for applications where a lower test current is appropriate.
This instrument is used by power utilities, electrical maintenance teams, and high-voltage switch manufacturers in China and internationally. Buyers sourcing from Wuhan should confirm the exact unit price, available calibration certificates, and shipping terms with GDMK Electric. Verifying the instrument's compliance documentation against your local regulatory requirements is recommended before import.

When importing electrical test equipment from China, verify that the instrument's specifications match the measurement requirements of your maintenance or manufacturing operations. Confirm the test current ranges, resolution, and compliance with the standards applicable in your jurisdiction. Request the full technical manual and a sample calibration report before finalizing the purchase order.
For precision instruments like micro-ohmmeters, shipping and handling are critical. Confirm with Wuhan GDMK Electric how the unit is packaged to protect against shock and vibration during transit. Ask about the lead time from order to dispatch, whether the instrument ships with all necessary accessories (test leads, power cable, carrying case), and the available Incoterms (FOB Wuhan, CIF your port, etc.).
Upon receipt, perform a functional verification using a known reference resistor to confirm the instrument reads within its stated accuracy. Check the calibration certificate's date and traceability. If the instrument does not perform to specification, clarify the supplier's process for returns, repairs, or replacements before you place your order to avoid disputes.
