7. START ON
Do not use the device outdoors during snowfall or rain. If the device is brought in during
the cold season from a cold room or from the street into a warm room, do not turn it on for
enough time to allow condensation to evaporate from the device.
Match the signal strength and voltage applied to ports P1 and P2 to the maximum device
specifications shown in Table 1.
7.1. Make sure that the device is not damaged externally and that the battery is charged. Charge the
discharged battery in accordance with item 11.2.
7.2. Press and hold button (6) for 2 seconds. The device turns on. When the device is turned on for the
first time, it is necessary to set the frequency range, the type of plots displayed on the screen (4) and car-
ry out calibration. User settings will be saved in the device memory and will be automatically installed on
subsequent switching on.
7.3. To turn off the device, press and hold the button (6) for 2 seconds. The display (4) of the device
will go out, the device will turn off. Each time the device is turned off, the main user settings are recorded
in the nonvolatile memory, which allows avoiding the device setting at the next turn on.
8. SCREEN INTERFACE
The device displays the results of scanning the frequency range specified by the user in the form of
plots and charts. The current device settings and interactive buttons for controlling the device interface
are located at the bottom of the screen.
Figure 8.1 - Device screen
8.1. The information bar of the screen displays information about the current state of the device.
8.1.1. Built-in battery status indicator:

indicator in the form of a spark (lightning)
– the battery is charging;

the battery indicator symbol is completely filled in white
– the battery is fully charged;

indicator symbol in the form of a white battery outline
– the battery is low and needs to be
charged;

the device displays a message about the critical charge level
– the battery is fully discharged,
the device will automatically turn off.
8.1.2. Frequency range:
• Numerical values of the beginning and end of the frequency range. In our example, the
frequency range is 1-6200 MHz.
In the mode of measuring the distance to fault, instead of the frequency range, the distance in me-
ters or time in nanoseconds is displayed.
8.1.3. Measurement mode:

S11
– the mode of measuring the reflection coefficient, cable loss and distance to damage;
