Multi-point measurement with the Multiplexer Unit Z3003 (20 locations with 4- terminal measurement) RM3545-02 Scanning measurement using the Multiplexer Unit Z3003 is convenient in applications that require multi-contact measurement, for example when testing network resistors, steering switches, or 3-phase motor windings. Simply insert a Z3003 unit into one of the slots on the back of the RM3545-02 to enable scanning measurement of up to 20 locations* with 4-terminal measurement. (*When using two Z3003 units, up to 42 locations can be measured with 2-terminal measurement.) Testing a...

Simplifying high-accuracy resistance measurement Standard features of the high-accuracy Resistance Meter RM3545 and RM3544 Convenient wide range options Measurement resistance range [Ω] Overview of the RM3545 Integrate into automated inspection systems Manual testing on production lines 0.01µΩ max. resolution, 0.006% basic accuracy 1µΩ max. resolution, 0.02% basic accuracy The RM3545 can perform resistance measurement with a 6.5-digit, 1,200,000-count display at a maximum resolution of 0.01 μΩ. It delivers more than enough capabilities to be used in applications requiring highresolution...

Super-high-accuracy, multi-channel resistance meter for use in advanced development and production applications Key Features of the RM3545 Low-power (LP) resistance measurement The RM3545 can perform measurement at a resolution of 10 μΩ at 1 mA (using the 1,000 mΩ range). With an open-terminal voltage of 20 mV or less, the instrument is ideally suited for measuring the contact resistance of chip inductors and signal contacts. The RM3545 converts resistance measured values into DC voltage for output. This capability is convenient when continuously recording changes in resistance, for example...

Easy-to-use RESISTANCE METER suits both manual operation and integration with automatic lines High-intuitive advanced functionality Guard terminals Minimize the effects of external noise on measurements. * GUARD terminal is the shield potential. This terminal is not for guarding network resistance measurements. Simple control over basic settings Range and measurement speed can be controlled directly. Functionality for saving and loading panels The RM3545 (RM3544) can save and load up to 30* (10) sets of range, comparator, and other settings. Naming each set of panel data lets you make setup...

Easy integration into automatic testing equipment (RM3545/-01/-02, RM3544-01) Ability to extend measurement cable length The new instruments feature better wiring resistance tolerances than previous models (the 3541 and 3540). Wiring resistance can now be as high as 1.5 Ω for the RM3545 and 2 Ω for the RM3544. High-speed, comprehensive productivity support • The RM3545 and RM3544 -01 deliver the speed demanded by automatic testing equipment at a sophisticated level. The entire process from the start of measurement to outputting of the judgment result takes as little as 1.9ms (RM3545) and 18...

Connecting the instrument to a computer via RS-232C or USB • Use a PC to control RM3545 and RM3544 -01 functions as well as acquire measurement results. (This capability does not include turning the instrument on and off or configuring certain interface settings.) • Connect the instrument to a commercially available RS-232C printer to print measured values, including judgment results. • Measured values can be automatically output. By using the instrument’s USB keyboard mode, measured values can be entered into applications such as spreadsheets and text editors without the need to install a...
