Description

The HT3542 Precision DC Resistance Tester is one of the most highly accurate DC Resistance Testers in the industry. The HT3542 DC Resistance Tester has a minimum resolution of 0.1μΩ. Its basic accuracy of 0.01% is well suited for inverter motor inspection and other areas that require high-resolution resistance measurement. The HT3545 features high-speed test lead anomaly detection and extremely short measurement cycles with a maximum sorting speed of 2.2mS, ensuring a fast and reliable sort every time. HT3542 is a compact version of HT3545.

Application-specific functions

HT-3542-High-Speed-High-Precision-DC-Resistance-Meter-03

Each test end is divided into 2 test lines, and a constant current source is added between the test lines. If the DUT is shorted at the end of the test, the current source outputs a low level, otherwise a high level. To check whether the test object or test lead has good contact.

Widerstandstester Kontaktprüfungsfunktion

Broken test leads and poor contact with the test object lead to incorrect assessments of the insulation test, which can lead to defective products on the market. In order to prevent this kind of situation, the device have a standard contact checking function, which can report the disconnection or bad contact to prevent the above situation.
