Overview

HT3542 Precision DC Resistance Tester is one of the highest-precision DC resistance testers in the industry.

The HT3542 is also can be work as multi-channel resistance tester. 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 HT3542 resistance meter, HT3542-12 and HT3542-24 is outstanding in anti-interference performance, make it very suitable for supporting automation equipment to complete automatic test.

Application Example1— Cable Detection Function

Circuit principle

Each test end is divided into 2 test lines, and a constant current source is added between the test lines. When the DUT is short-circuited at the test end, the current source outputs a low level, otherwise it outputs a high level. Use in this way to check whether the test object or test line is in good contact.

Application Example2—Poor Contact Inspection

Broken test leads and poor contact with the test object will lead to misjudgment of the insulation test, which may cause defective products to flow into the market. In order to prevent this kind of situation, we have a standard contact check function, which can notify the disconnection or poor contact to prevent the above situation.
