05 Display Mode

There are three modes to choose in Display Mode: Real Time, Snapshot and Peak Hold. Real Time is the standard operation of the instrument. For basic inspection operations choose Real Time. Snapshot is a very useful mode for inspections that require a comparison of measurements. Snapshot holds a specific reading on the display. The display can be updated by releasing and pressing the trigger. An example of this operation mode would be to locate the loudest point in a machine. By pointing the instrument at a loud signal and pulling the trigger, the sound intensity level will be displayed on the panel and held for comparison as the instrument is scanned around other points on the machine. The meter will remain constant while the audio levels change. Another example is performing a quick comparison of multiple bearings by pressing and releasing the trigger to update and compare sound levels. Peak Hold displays and holds the peak value for comparison. It changes only when a higher ultrasound level is sensed. The bar graph will move up and down to display sound intensities, but the Peak Hold dB reading in the upper left corner will remain constant. A thin vertical line on the bar graph indicates the peak intensity of the bar graph. The Peak Hold dB reading is reset by turning the instrument off or by changing the frequency.

To select Display Mode:

1.Make sure the Ultraprobe is off.

2.Press (click) both the Yellow Store button and the Sensitivity dial at the same time, then squeeze and hold the trigger.

3.When in the first Menu Selection : “Data Transfer” (Menu 01), you may move to any of the other Menu Selections by spinning the Sensitivity Control up or down (clockwise or counter clockwise).

4.Spin to Display Mode (Menu 05 Blinks).

5.Click the Sensitivity Control to enter Display Mode.
