Test mode

Introduction
Test mode is used to check whether:
● The acoustic emission sensor is assigned to the correct acoustic channel.
● The acoustic emission sensor is functioning.
In test mode, the acoustic emission sensor is sensitive to both temporary knocking noise as
well as permanent flow-generated noise. The maximum sound pressure level measured is
saved and displayed.
Condition
The measurement channel must be in test mode. The measurement channel is in test mode
if the parameter P.1 to P.4 associated with the measurement channel is set to "tESt".

Use the and buttons to select the measurement channel which you wish to
simulate. Measurement channels 1 to 4 (1/So1 to 4/So4) are possible. For example, if
measurement channel 1 is selected, "1/So1" is displayed to the right in the middle section
of the digital display. "SIMU" is shown in the lower section of the digital display.
