Digital ohmmeter RESISTOMAT® 2320

portable4-wirebattery-powered

The RESISTOMAT® model 2320 is a universally applicable and easy to operate measurement device for low-ohmic resistances. The light and handy device in a stable IP54 plastic housing with membrane keypad is likewise suitable for use in service, laboratory or on the production floor. The power supply is done via built-in rechargeable battery packs or by standard batteries. If need be, the temperature of samples can be measured and the sample resistance is subsequently compensated to fit the value at 20°C. This applies for samples with resistances depending on the sample’s temperature. The temperature coefficients for copper and aluminium are included as standard. A third and fourth coefficient may be set individually for any given material to be measured. The application range is manifold, such as measurement of: resistance elements plug connections power rails fuses cable connections transformers electrical motors cable and wire, and many more The 4-wire measurement configuration eliminates possible errors caused by test lead and contact resistance. This is the basis for resistance measurements in the mΩ range. The resistance value calculated in the current voltage method is then indicated on the large LCD display in mΩ, Ω or kΩ. Single as well as permanent measurements are possible whereby the 6 measurement ranges can be selected in manual or automatic mode. The standard resistance value at 20 °C is calculated and displayed if the temperature compensation is active. The measured temperature may also be displayed directly. Thermo voltages are eliminated by the bipolar current source and the calculation of the mean value (key AVE).
