Model 2329
The Resistomat Model 2329 is particularly suitable for quick measurements of low resistances in automated processes. Fifty measurements per second can easily be performed.

The PLC interface allows the easy addition of external lights and buzzers to make the unit suitable for production settings.

Test of Airbag Triggers
Airbag triggers are tested by a Resistomat Model 2329-v801 in a test stand. The measurement conditions, such as measuring current < 10 mA and load voltage < 2 V, which are an absolute must, are guaranteed with Model 2329-v801. The triggering of the t est unit and the control of the production line are performed by a PLC. The information "okay" or "not okay" about the test sample is provided by the Resistomat Model 2329-v801.

The PC is used for the parametric setting of the test unit, such as measurement range and the limit values, as well as for the registration and statistical evaluation of the measuring data.

Testing Instruments for the Highest Demands
  • Automatic choice of measuring ranges from 200 µOhm to 20 kOhm
  • Resolution up to 1 nOhm
  • Serial interfaces (IEEE-488, RS-232, RS-485), tolerance checking, classification with statistics
  • Measuring error < 0.01%, trendsetting measurement with thermal e.m.f. compensation
  • Current regulation results in voltage-free disconnection
  • measures current up to 1 A or 10 A
  • Setting of measurement current, entry for absolute or relative limits, bar display for calibration of measuring probes, determination of resistivity and many other functions.
