Resistance Meter

Over time, manufacturers of chip resistors and taping machines* have made known to HIOKI their desire for an ohmmeter that could be integrated into an automatic testing system to provide a rapid, 100% inspection capability. The RESISTANCE HiTESTER RM3542 meets this need by:

• Contributing to a dramatic increase in efficiency in shipping inspections of resistors and other components thanks to its ultra-high measurement speed and precision
• Contributing to improved reliability by monitoring whether measurement is being performed in a reliable manner by means of a continuous contact check function

Taping machine: A device that picks up, tests, and packages components such as resistors and chip inductors on a mass production line.

Industry-leading ultra-high-speed and ultra-high-precision resistance measurement

• The RM3542 employs the DC four-terminal method to measure resistors, chip inductors, EMC components, and other parts at high speed and precision. The instrument can test 1% tolerance (F-type) resistors in as little as 0.9 ms (according to HIOKI findings).

• Under standard settings, accuracy of ±0.011% is guaranteed for 1 kΩ measurement in fast mode (at a measurement speed of 0.9 ms).

High-resolution, 7-digit display

• Thanks to its high-resolution, 7-digit display and broad measurement range of 0 Ω (0.0000 mΩ) to 120.0000 MΩ, the RESISTANCE HiTESTER RM3542 can also test 0.1% tolerance (B-type) resistors.

Contact check to ensure measurement reliability

• A continuous contact check function monitors whether the resistor or other component under measurement is being properly measured at all times. A voltage monitor function can detect failed measurements, and the instrument can repeat measurements in a reliable manner. This functionality combines to increase measurement reliability.

Low-power resistance measurement

• The RM3542 supports low-power resistance measurement with limited measurement currents in the 1,000 mΩ to 1,000 Ω range, enabling testing of parts such as chip inductors and EMC components that must be measured using low currents.

Saving and outputting measured values

• The RM3542 can store up to 30,000 measurement datapoints in its memory. The ability to transfer measurement data for an entire reel of chip resistors to a computer or other device after testing of the reel is complete makes a significant contribution to quality control.

Applications:

• Use with taping machines
• Use with automatic testers that perform resistance measurement
• Testing and sorting at resistor manufacturers’ facilities
