The RESISTOMAT® model 2320 performs single and permanent measurements, whereby the measuring changeover from 40.00 mOhm at 10 µOhm resolution up to 4.000 kOhm may be done either automatically or manually. The measuring accuracy is < 0.05 % rdg. plus 2 counts. Unipolar and bipolar measurements are possible. On temperature dependent test objects the temperature can be measured in combination with a Pt 100 sensor and the object's resistance is subsequently compensated to fit the value at 20 °C. The temperature coefficients for copper and aluminium are included as standard, two more coefficients may be set individually for any given material to be measured. The input voltage protection is dimensioned for voltage peaks up to 415 Vrms which is of advantage especially for the measurement of inductive test objects.
The resistance value calculated in the cur-rent-voltage method is shown on the large LCD display directly in m?, ? or k?. Low battery charge is indicated by LED "LOBAT". The battery pack can be replaced in a very simple manner and recharging is done in an external loading station. The RESISTOMAT® model 2320 is supplied including batteries and calibration certificate. Optionally available are Pt 100 temperature sensors, Kelvin measuring pliers and probes, clamping devices and calibration resistances. Further accessories are rechargeable and spare battery pack with external loading station and a practical carrying bag.
