2304, Electrical Resistance Testing
- Automatic choice of measuring ranges from 200 ohms to 20 ohms
- Resolution up to 1 ohm¸
- Standard interfaces IEEE488, RS232, RS485, USB (option)
- Checking of tolerances, classification with statistics
- Measuring error ≤ 0.01 %
- Future-orientated measuring method with thermal e.m.f. compensation.
- High level of stability due to constant comparisons with internal reference values.
- Current regulation results in voltage-free disconnection, calculation of cooling curves of coils.
- Setting for measuring current entry for absolute or relative limits, classification with statistics, bar display for calibration of measuring probes, determination of resistivity, and many other functions.
Apart from eliminating the error of contact layer and contact resistance, this method has the advantage that errors reduce to the quality of the internal reference resistors alone. The deviations in these reference resistances are well known and accounted for the multiplication.
The result is that the resistance of the test object can be determined very quickly and accurately irrespective of the resistances present in the current circuit.
In order to meet high standards in measuring and testing requirements the device was equipped with an integrated high-resolution A/D converter with particularly low linearity deviations. The test objects are measured at both poles, thus eliminating parasitic thermal e.m.f. voltages.
The quotient measuring method used, with constant comparison function automatically ensures zero point calibration. Thus an optimum measuring accuracy is guaranteed.
The unit features an extensive standard software for storing measured cooling curve values, temperature compensation, classification, statistical functions, printer and interface drivers, clock, line frequency adaption.
Two microprocessors ensure optimum and exact measuring and testing. For PC user the device software 2304-P001 is available.
