Description
The HT3548 Precision DC Resistance Tester is one of the most accurate 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 3MΩ. Due to the minimum resolution of 0.1 μΩ and a measurement accuracy of 0.02%, the resistance tester is well suited for inspection of 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.
Features
- Offers 0.02% basic accuracy, 0.1μΩ minimum resolution, 1A maximum test current
- With measurable range 0.1μΩ~3.3MΩ.
- Anti-interference measurement is achieved by protecting the probe used by the port and increasing the test current.
- Sorting indicator (option) with loud volume can accurately judge whether it is qualified or not at the production site.
- Equipped with RS232/RS485/LAN interfaces and EXT I/O port, the HT3544 multi-channel ohmmeter is particularly suitable for supporting the ATE line to perform automatic tests.
- Compact and portable structure with powerful function
- Unique test lead length function
- Unique 300mA current test
- The reading is automatically held and saved
- Has a stable reading (averaging function)
- With thermoelectric compensation function (OVC)
