Features
Reduce the effects of thermoelectromotive force with the offset voltage correction
Thermoelectromotive force refers to the potential difference that occurs at junctions between different metals (see figure). Specifically, the phenomenon occurs where measurement probes and measurement targets come into contact, and at connections between measuring instruments and measurement leads. The magnitude of this thermoelectromotive force varies with the temperature of the measurement environment, increasing as the temperature difference grows. The RM3548 includes an offset voltage correction function that applies the measurement current in both the positive and negative directions and then uses the resulting detected voltages to eliminate the effects of thermoelectromotive force.
Correct resistance values, which vary with temperature, to a reference temperature with the temperature correction 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 RM3548’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 Z2002 (which comes with the RM3548) is used to perform temperature correction.
Standard-compliant measurement current for EV’s equipotential bonding test
The RM3548 stands out as the perfect resistance meter for technicians performing equipotential tests on electric vehicles. This meter complies with the ECE-R-100 and ECE-R136 standards, meeting measurement current requirements of at least 0.2 A. Its measurement current ranges from 500 nA to 1 A, ensuring accurate and reliable readings.
