Resistance Meter Kit (RM3545A-1, L2101, Z2001)
As electric mobility gains popularity, manufacturers are developing components for higher currents and voltages. Since even minuscule amounts of resistance can have a significant impact on energy efficiency and safety, more accurate quality control focusing on resistance is required. The Resistance Meter RM3545A facilitates accurate resistance measurements and is suitable for diverse applications in development and production lines.
This kit adds a clip-type lead (L2101) and a temperature sensor (Z2001).
Measure low resistance values at high precision and high, 1 nOhm resolution
Electric resistance is measured by passing a current through a measurement target such as a weld. Pass and fail judgments are generated based on variation in resistance values. A typical low-resistance weld can have resistance ranging from 10 uOhm to 100 uOhm. The Resistance Meter RM3545A provides a 1000 uOhm range and 1 nOhm resolution, allowing it to measure low resistance values with a high degree of precision. If a weld is insufficient, its resistance value will exceed that of a non-defective weld. Pass and fail results are generated for non-defective and defective welds based on minuscule differences in their resistance values. Weld quality can be managed quantitatively for all welds passing through a production line, ensuring traceability.
Ensuring precision in resistance measurement
Offset voltage correction function (OVC)
When measuring low resistance, due to the voltage generated when different metals come into contact with one another (known as electromagnetic force, or EMF), the measurement values can be unstable. The Hioki RM3545A is built in with an Offset Voltage Compensation (OVC) function to correct for the effects of EMF, making the instrument ideal for measuring low resistance of the welding points of busbars.
Temperature coefficient of resistance
The resistance values vary with temperature. To ensure consistent testing with a resistance meter, it is necessary to eliminate the effects of temperature. The RM3545A has got you covered.
Temperature correction (TC) function
Temperature correction functions can convert readings to resistance values at a user-specified reference temperature and display the results, even for materials such as copper wire whose resistance varies with temperature. The RM3545A's temperature correction function converts the measured resistance value Rt at the current temperature t to the resistance value Rt0 at the reference temperature t0, as shown in the figure. The Temperature Sensor Z2001 (included accessory) is used to perform temperature correction.
Temperature measurement function
When using the Temperature Sensor Z2001, the instrument can measure temperature with a high degree of precision (+/- 0.5C). It can also accept analog input from a radiation thermometer (0 V to 2 V).
Temperature conversion function
This function calculates and displays temperature rise from the measured resistance value and ambient temperature.
