## Long description

The Uni-T UT620C+ Digital Micro-Ohmmeter is a high-precision testing instrument engineered for the accurate measurement of low resistance values. Designed for professionals, this device excels in evaluating electrical contacts, circuit breakers, switches, and grounding systems. By utilizing advanced measurement techniques, it ensures stable and reliable data for both industrial and laboratory environments, facilitating precise diagnostics of conductive materials and electrical components.
Advantages
This micro-ohmmeter stands out due to its exceptional measurement range and high resolution, which allows for the detection of even the smallest resistance variations. The integration of the four-wire measurement method effectively eliminates the influence of test lead resistance, ensuring that the readings are highly accurate and repeatable. Its robust construction, combined with an IP54 protection rating, makes it a durable tool capable of withstanding the rigors of field work and workshop conditions. Furthermore, the inclusion of internal memory for data storage and a clear, backlit display enhances operational efficiency during complex testing tasks.
Suitable for
Testing electrical contact resistance in switches and relays
Verifying the integrity of grounding systems
Measuring resistance in circuit breakers and fuses
Analyzing the resistance of metal components and conductive materials
Quality control in electrical manufacturing and repair
When it may not be suitable
The device is specifically optimized for low resistance measurements and may not be the most efficient tool for general-purpose high-resistance insulation testing or standard multimeter functions like voltage or current measurement beyond its specified range. It is not intended for use in high-voltage power distribution networks exceeding its input protection limits.
Key specifications
Resistance measurement range: 0.001 mΩ to 300 kΩ
Resolution: up to 1 μΩ
Measurement rate: approx. 2 readings per second
Memory capacity: 500 data sets
Input protection: up to 36 V AC/DC
Protection rating: IP54
Interface: USB Type-C
Power supply: 3.7 V / 3200 mAh Li-ion battery
How to use
To begin, ensure the device is charged and powered on. Connect the test leads to the object being measured using the four-wire configuration to minimize lead resistance errors. Select the appropriate measurement range or use the auto-ranging function. Once the leads are securely attached, the measurement will appear on the backlit LCD. You can save the results to the internal memory for later analysis or transfer them via the USB interface. Always ensure the circuit under test is de-energized before connecting the probes to prevent damage to the device.
What to consider before purchase
Verify that the resistance range meets your specific application requirements
Ensure the four-wire probe configuration is compatible with your test points
Confirm that the environment does not exceed the IP54 dust and splash protection rating
Check if the data storage capacity is sufficient for your documentation needs
Usage recommendations
Always perform a calibration check before critical measurements to ensure accuracy. Keep the test leads clean and free of oxidation to maintain the integrity of the four-wire measurement method. Store the device in a dry, temperature-controlled environment when not in use to prolong the lifespan of the internal lithium-ion battery.
