The milliohmmeter serves the high precision measurement of resistance. The milliohm meters 2515 and 2516 with high basic accuracy are ideal for use in laboratories, in the higher education sector or in production. There are resistance gauges with automatic range selection and hold function, which can operate in a particularly simple way. Moreover, all ranges also are manually adjustable. Most importantly, both milliohm meters have a special comparison function, a comparator with PASS / FAIL evaluation. This can automatically sort out BAD parts. It is a milliohm meter with a few extras, e.g. battery backup, password protection and speaker. The brilliant large screen is bright and clear and allows a wide viewing angle, ideal as a laboratory instrument or as milliohm meter in an automatic test system. The measurements of the milliohm meter can be quickly read out through the digital interfaces. The simple ohmmeter intuitive command set, which follows the SCPI standard, allows integration into existing instrumentation. The whole thing is controlled either via external, internal or fuzzy trigger. All in all, it is a very low resistance ohmmeter with four-wire measurement procedures, a powerful resolution and a high current measurement for measuring small resistances. Milliohm meters of this type are ideal for laboratory applications for the automotive industry, aircraft construction, the quality testing of mechanical connections and contacts, in automatic test systems and anywhere else where low-resistance measurement is needed.
