Electronic Resistance Tester for Batteries

The AC Milliohmmeter is an intelligent and high-performance tester that is widely used to test contact resistance, internal resistance, and battery voltage. The application of a constant current source with a 1kHz frequency can effectively eliminate the potential error caused by thermoelectricity on the device under test (DUT). This meter has the ability to automatically detect contact failures on the test cable. At the 30mΩ range, the basic resistance resolution can reach 1μΩ. It is applicable for a variety of applications, including transformer, inductance coil copper resistance, relay contact resistance, switch, connector contact resistance, wire resistance, PCB line and via resistance, and metal defect detection. Additionally, the meter can output signals such as HIGH, LOW, and PASS through the HANDLER interface, making it convenient for use in automatic production lines.

The use of a constant current source with a 1kHz frequency is a key feature of the AC Milliohmmeter, as it can greatly reduce the potential error caused by thermoelectricity on the DUT. This is an important consideration when measuring low-resistance values, as the thermoelectric effect can introduce significant errors. By using a high-frequency alternating current, the meter is able to overcome this limitation and provide more accurate and reliable measurements.

Another notable feature of the AC Milliohmmeter is its ability to automatically detect contact failures on the test cable. This is a valuable function, as poor contact can lead to inaccurate readings and potentially impact the overall reliability of the measurement. The automatic detection of such issues helps to ensure that the user is alerted to any potential problems, allowing for timely troubleshooting and correction.

The meter's wide range of applications is another key strength. It can be used to measure the resistance of a variety of components and materials, including transformers, inductance coils, relays, switches, connectors, wires, PCB traces, and even metal defects. This versatility makes the AC Milliohmmeter a valuable tool for a wide range of industries and applications.

Finally, the integration of the HANDLER interface is a convenient feature that allows the meter to be easily integrated into automated production lines. The ability to output signals such as HIGH, LOW, and PASS can be used to trigger downstream processes or provide feedback to the operator, improving the overall efficiency and reliability of the production process.

In conclusion, the AC Milliohmmeter is a highly capable and versatile tester that offers a range of advanced features and capabilities. Its ability to accurately measure low-resistance values, automatically detect contact failures, and be seamlessly integrated into automated production lines make it a valuable tool for a variety of applications and industries.
