Resistance tester series HT3548

The HT3548 precision DC resistance tester is one of the most precise DC resistance testers in the industry. The HT3548 DC resistance tester has a 4.3 inch display and has a measuring range of 3mΩ to 3 MΩ. Due to the minimum resolution of 0.1 μΩ and a measurement accuracy of 0.02%, the resistance tester is well suited for inspecting converter motors and other applications that require high-resolution resistance measurement. Equipped with RS232 / RS485 / LAN interfaces and EXT I / O port, the devices of the HT3544 resistance tester series are suitable for performing automatic tests in test or production lines.




Main features of the HT3548 resistance tester

  • Offers 0.02% basic accuracy, 0.1μΩ minimum resolution, 1A maximum test current
  • With measurable range 0.1μΩ ~ 3.3MΩ.
  • The anti-interference measurement is achieved by protecting the probe used by the port and increasing the test current.
  • Using the sorting display (option) with a loud volume, it can be precisely assessed whether it is qualified at the production site or not.
  • Equipped with RS232 / RS485 / LAN interfaces and EXT I / O port, the HT3544 multi-channel resistance meter is particularly suitable for supporting the ATE line for performing automatic tests.
  • Compact and portable structure with powerful function
  • Unique test lead length function
  • Unique 300mA current test
  • The measured value is automatically held and saved
  • Has a stable measured value (mean value function)
  • With thermoelectric compensation function (OVC)





Areas of application of the HT3548

The devices of the HT3548 series have a wide range of fields of application. Various resistances with high, medium and low values, various switch contact resistances, connection resistances, relay cable packages, contact resistances, transformers, inductors, motors, winding resistances of a deflection coil, wire resistances and more can be measured.
