Overview
HT3542 Precision DC Resistance Tester is one of the highest-precision DC resistance testers in the industry. HT3545 DC resistance tester is 6 1/2 and 1.200,000 display, the minimum resolution can measure 0.01μΩ. Its basic accuracy of 0.01% is quite fit in the inverter motor coil inspection and other fields requiring high-resolution resistance measurement. The HT3545 features high-speed test cable anomaly detection and extremely short measurement cycles, with a maximum sorting speed of 2.2 mS, ensuring high-speed and reliable sorting every time. HT3542 is a compact version of HT3545. |

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 Example
| 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. |
PCB Board Test
| For some PCBs with high requirements in aerospace, automotive electronics, etc., it is required to test their vias and traces. With the support of multi-channel switching equipment, HT3545 precision resistance tester offers its scanning and switching at the speed of 2ms per channel. |
HT3542 single-channel Resistance Tester is suitable for the following application
