Specifications

• Measurements are always automatically
recorded to instantly show changes over time

• Use cursors to read time and date of sags
and swells

• Catch voltage transients and waveform
distortion down to 40 nS

• Catch and save up to 40 transients

• Correlate the cause of transients with time
and date stamps

Accuracies are stated as ± (percentage of
reading + counts) without probes unless

Specifications are valid for signals with a
fundamental between 40 and 70 Hz.
