Overview
The HT3544 multi-channel resistance tester is a new generation product from Hopetech Technology. Each model has two-wire and four-wire switchable modes. They realize maximum two-wire 48-channel resistance test and four-wire 24- channel resistance test. Based on the identical circuit design of the classic model HT3544 resistance meter, HT3544-12 and HT3544-24 is outstanding in anti-interference performance, make it very suitable for supporting automation equipment to complete automatic test. |
Offering 0.02% basic accuracy, 0.1μΩminimum 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. Using the sorting indicator (option) with loud volume sound to accurately judge whether it is qualified or not at the production site. Equipped with RS232/RS485/LAN interfaces and EXT I/O port, HT3544 multi-channel resistance meter is especially suitable for supporting ATE line to complete automatic test.
