If the MUTE key is pressed and immediately released, the device considers this as an
invalid action and ignores the collected data.

Minimum and Mean Values: the corresponding numerical values of MIN and MEAN of the
measured signal are displayed under the column on which the bar (or line) graph of the
same color is displayed. Each measured point can be recognized by its numerical index
below the minimum and mean values box. The device can count to 2000 points every time
it turns on.
10-
Leak Mark: when certain of leakage at a given point, the user may move the cursor to the
corresponding index and mark it by pressing the EXIT key. In this situation, a water drop
symbol appears under the column. To cancel this and unmark the column, press the EXIT
key again. Please note that the user may detect more than one leakage and, accordingly,
mark more than one point. Marking the leak points improve the data organization in the
device as well as HSS-Application.

High Pass Filter (HPF) Cut-off Frequency: This version of PERIJA Plus has been equipped
with three HPF with cut-off frequency of 100 Hz, 200 Hz, and 400 Hz. Item 11 indicates
the selected HPF cut-off frequency, and the user can change it using the HP key.
12-
Low Pass Filter (LPF) Cut-off Frequency: This version of PERIJA Plus has been equipped
with three LPF with cut-off frequency of 400 Hz, 600 Hz, and 1200 Hz. Item 12 indicates
the selected LPF cut-off frequency, and the user can change it using the LP key.

filteROT™ Mode Indicator:
I
f the user intends to use the filteROT™ work mode, the FILTER
SCAN key on the key panel should be pressed. As long as the device is operating in this
mode, a cyan bullet appears on the right-hand side of the screen. For further information
on the filteROT™ mode, please refer to the section entitled “filteROT™ MODE.”
14-
Sensitivity Level: The sensitivity of the device is displayed using a numerical value as well
as a curved bar-graph. The bar-graph that indicates the sensitivity level is green for values
between 0 and 59, yellow between 60 and 80, and red for values between 80 and 100.
The selected colors are in accordance with the standard color scheme of danger or
warning signs.
With high sensitivity level, there is a chance that the user’s hearing capacity
may be saturated and temporarily dulled in a way that the user cannot be able
to discern the leakage sound. Therefore, it is recommended that the device
not be used for prolonged periods of time at high sensitivity.
While using headphones, ambient sounds such as the warning sounds
produced by vehicles may not be audible for the user. Therefore, ensure all
safety precautions before operating the device at the project location.
15-
Global Positioning System (GPS): The GPS is installed on the device and functions as a high-
accuracy CEP module which works with a maximum CEP (circular error probable) of 2.5
meters. If the user leaves the GPS function switched on in the SETTINGS, the numerical
values of latitude and longitude are displayed on the screen and updated every second. It
should be noted that each time the values of received signals are saved, the device also
stores the other relevant values and information such as battery life, date, time, GPS
information, selected filters, etc.
If the GPS function is turned off, the data saved by the device will not include
the geographical location of each project and, naturally, the location cannot
be displayed on the Google Maps application or other GIS-ready maps.
