Resistomat 2304 precision ohmmeter

The Resistomat 2304 precision ohmmeter allows for the automatic inspection of resistances to high accuracy.

Measuring ranges for this model can be changed automatically from 200 µΩ to 20 kΩ. The resolution can be up to 1 nΩ and measuring error is less than 0.01%. The measuring method includes thermal EMF compensation and there is a high level of stability due to constant comparisons with internal reference values.

The ohmmeter’s menu options include settings for measuring current entry for absolute or relative limits, classification with statistics, bar display for calibration of measuring probes, determination of resistivity.

Standard interfaces include IEEE488, RS232, RS485 and USB (optional).

The ohmmeter is suitable for applications including high-precision measurement of ohmic resistances in various environments, series tests with programmable frequency distribution and switch output per class (histogram), calibration in production, measurements on coil, motor and transformer windings, recording of cooling curves, determination of resistivity values with material-related temperature compensation and measurement of contact resistances.

The resistance test unit features software for storing measured cooling-curve values, temperature compensation, classification, statistical functions and line frequency adaption.
