Comparator function memorizes up to seven tables. Dual comparator modes: Hi-Lo compares upper and lower limits, and REF-% compares a range and standard value. Fast response of about 100 ms (measuring pure resistance: actual response depend s on material under test) Temperature compensation function measures temperature and calculates value rela tive to copper at 20°C/68°F. Utilizes 4-terminal method to eliminate effects of leads and contact resistance. Auto-ranging function. Dual power system: batteries or AC adapter. BCD, printer interface and RS-232C interface options in -01, -02 and -03 suffix versions, respectively.
DC Milliohm Hi-Tester (RS-232C Interface)
The 3540 m-Ohm HiTester includes a comparator function essential for component sorting, fast 16 times-per-second sampling, temperature compensation and auto-ranging, and a choice of versions depending on usage. The 3540-03 includes a RS-232C interface.

Comparator Function
The comparator includes a Hi-Lo mode for setting upper and lower limits, and a REF-% mode for setting a standard value and range. Up to seven tables can be memorized, each storing a measurement range, comparator mode and comparator values. Hi/IN/Lo measurements are indicated by LED and 3-way beeper mode, and for the -01 and -02 versions, results are available for external use at open-collector output terminals on the rear panel.

Specific to 3540-03
This model is equipped with an RS-232C interface. Through this interface, all features of the instrument other than the power supply can be controlled remotely. Measurement data can also be output through the interface for processing by various applications, increasing the scope of data utility.
