OM 402UNI

4-DIGIT MULTIFUNCTION INSTRUMENT

The OM 402 model series are 4-digit panel programmable instruments designed for maximum usefulness and user comfort while maintaining their fair price. Type OM 402UNI is a multifunction instrument with the possibility of configuration for 8 different input options, easily configurable in the instrument menu. By further options of input modules it is feasible to measure larger ranges of DC voltage and current or to increase the number of inputs up to 4 (applies for PM). The instrument is based on a single-chip microcontroller with a multichannel 24-bit sigma-delta converter, which ensure good accuracy, stability and easy operation of the instrument.
