Specification

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 3540-01 adds BCD output and external control.

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.

This version is equipped with a digital interface providing BCD output of comparator results and external control capability, as well as the essential functions of the 3540. Along with BCD output, the range, comparator tables, EOC and power can be externally controlled, ideal for system applications.

Features:
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 depends on material under test)
Temperature compensation function measures temperature and calculates value relative 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.
