PM 6303A RCL Meter

The PM 6303A is quick and simple to operate, on the manufacturing floor as a quality assurance tool or in the service lab for quick tests


Effective, economic testing that's quick and easy to use

The PM 6303A is quick and simple to operate, on the manufacturing floor as a quality assurance tool or in the service lab for quick tests of a wide variety of components. Its simple operation and 0.25% basic accuracy make the PM 6303A equally at home in the classroom for education and training environments.

• 0.25% basic accuracy
• 2V dc internal bias
• Automatic zero trimming
• Front-panel test posts for immediate 4-wire measurements

Easy-to-use, at-a-glance display of relevant information

The PM 6303A is the fast and simple way to get information about the value and electrical characteristics of any component. Just connect the component and read-out the value, the units and the equivalent circuit diagram from the large, backlit LCD display. This versatile meter gives you 9 specific parameter tests, with switchable dc bias for components that need it. At the push of a button you can select series or parallel resistance, capacitance, inductance, impedance, Q (quality) and D (dissipation) factors, and phase angle.

Quick and simple component connection

Connection of test components is quick and simple; either directly to the detachable test posts which are conveniently located on the front panel, or using the PM 9542A universal test adapter. The optional PM 9541A test cable with Kelvin clips provides a unique solution for flexible attachment to mounted components while retaining the extra accuracy of the 4-wire measurement principle.

The PM 6303A also handles surface-mount devices (SMDs) quickly and efficiently, using the optional SMD accessories. All measurements are made using a 4-wire technique, which ensures high-accuracy measurements, even for low-impedance components.

Easy operation

Thanks to its easy operation, the PM 6303A is the ideal choice for general-purpose component testing in service and troubleshooting, component identification in the lab, quality control, batch sampling and incoming inspection, to name just a few. Its clear, simple operation and quick results display make it equally ideal for education and training.
