5.7 Ultrasonic Screen
The Ultrasonic screen shows measurements taken using either the inbuilt Ultrasonic sensor
or the external Ultrasonic sensors (Contact Probe, Flexible Sensor or UltraDish) if
connected.
Ultrasonic magnitude is measured in dBµV and is displayed on the chart as phase angle (x-
axis) against amplitude (y-axis). The colour chart represents a key to show the intensity
(pulse count) at a given amplitude and phase angle.
This phase resolved plot can be used to further confirm the presence of a partial discharge
activity. In general PD activity will be displayed as a stable area which will occur at the same
to phase angle each cycle; whilst noise tends to be out of phase and occurs at irregular
positions on the phase plot.
The Pause and Record option is also available in this mode as described
under the Measure Screen
