GALLUNOPTIMAL Skala 400 digital multimeter
This digital multimeter measures DC and AC voltage, DC and AC current, resistance, temperature, continuity with audible signaling, capacitor/diode/transistor test, NCV test, frequency and duty cycle.
The measuring range is selected automatically or can be selected manually.
Other functions include polarity display, data hold, relative data measurements, overrange display and an audible signal for continuity measurement.
The digital multimeter was developed in accordance with EN61010-1 for electronic measuring instruments with overvoltage category (CAT III 600V and CAT II 1000V) and pollution degree 2.
Highlight: True RMS
Unlike an average multimeter, a True RMS meter always measures the RMS value of the current, even if the waveform deviates from the perfect sine wave. The multimeter has a special electronic component for this purpose.
