The Junior, Micra and Pica models admit both alternating and direct voltage and current signal inputs for industrial signal monitoring. They are easy to scale into desired engineering units, directly by frontal keys or real input signal value in teach mode.  Universal AC/DC voltage supply.  Capable of measuring AC/DC voltage in 600V, 200V and 20V ranges, AC/DC current directly or through a current transformer in 5A and 1A ranges or through an external shunt in 60mV and 100mV ranges.
