Powerscope 880

A very popular, award winning instrument for precise measurement via 4 Independent differential channels to display waveforms associated with AC and DC power engineering.

It won an Australian Industrial Design Council award for its originality in design concept and the high degree of safety to the operator and was sold around the world.

The Powerscope can measure signal levels of 100mV to 600V RMS across circuit components that are directly connected to three phase powerlines. DC measurements can be made to ±500V, and accessories are provided to extend this range to +2kV or 1.5kV RMS.

Bandwidth is from DC to 7.5MHz, and timebase ranges from 100ns to 100 seconds are provided, with triggering extending from DC to 10MHz.

A unique feature of the Powerscope is its ability to provide the user with a digital readout of phase angle between a zero crossover reference marker and a variable marker. The variable marker can be adjusted from 0° to 359° in 1° steps, and can be repositioned in multiples of 60° to provide immediate phase angle relationships in two, three or six phase systems. Four channels facilitate measurements in three phase supplies, revealing detailed performance of thyristors, triacs and ignitrons under actual operational conditions.

The oscilloscope is provided with a completely insulated cabinet, which has been tested to withstand over 5kV. The heavy duty probes are shrouded and will withstand transients up to 3kV. The instrument can be operated either from the mains, from a 20-30V DC source or from a rechargeable battery pack.
