Gently measure minuscule electronic components (0201 size) with functionality for limiting the applied voltage

By limiting the voltage that is applied during measurement to 5 V or less, the RM3542A makes it possible to measure 0201-size components that have low rated voltages without stressing the parts.

Ensure reliable contact quickly with the contact improvement function

The RM3542A improves contact with measurement specimens by eliminating oxide films and dirt between the probes and specimens. By addressing faulty contact, the instrument facilitates stable measurement and reduces the contact error rate, boosting productivity.

Utilize a more evolved contact improvement function in low-power measurement

The RM3542A allows contact improvement to be used in a broader range of situations, for example testing of compact ferrite beads and minuscule, 0201-size resistors, by limiting the inrush current that flows to the measurement specimen during operation of the function.

Use the scaling function to correct measurements as if the target component were mounted

The RM3542A’s scaling function can correct for the difference in resistance values that are obtained when testing a given component alone and when it is mounted on a circuit board (due to the factors such as the effects of probing position). This feature is useful when testing low-resistance current-sensing resistors such as shunts.
