2. Function description
2.1 Functional principle
The LEAKPEN is a battery-operated, acoustic measuring and listening device for leak detection in pressurised water pipes.
The acoustic sensor picks up sounds from water pipes under inspection. The leak is located at the point with the loudest sounds.
The LEAKPEN transmits audio signals to headphones using Bluetooth technology. To provide the best audio quality, analogue automatic gain control (AGC) is used.
2.2 Measuring principle
The LEAKPEN continuously measures the audio signal level and displays the minimum measured value within one second intervals via the 9 red LEDs.
Listening to the audio signal provides additional information about the type of sound and its origin.

3. Preparation
3.1 Insert / replace battery
To avoid discharging the battery during storage and transport, no battery is inserted in the LEAKPEN when it is delivered.

| D | Negative battery pole |
| E | Sealing ring |
To install or replace the battery, proceed as follows:
1. Unscrew the battery compartment cover (Figure 3, [A]) from the LEAKPEN.
2. Insert a battery or replace the old one (Figure 3, [B]), and pay attention to the polarity of the battery (Figure 3, [C] & [D]).
3. Make sure that the sealing ring (Figure 3, [E]) is correctly seated and not dirty or damaged.
4. Screw the battery compartment cover back onto the LEAKPEN.
5. The LEAKPEN starts directly in bootloader mode (Figure 4 and see chapter 4.4 Bootloader mode)
a. This will end after 4 minutes and the LEAKPEN will switch to sleep mode (OFF).
b. If no firmware update is required, the bootloader mode can be terminated and the LEAKPEN can be set to sleep mode (OFF) with one shake.
6. The LEAKPEN can now be switched on (see chapter 3.2 Turn ON / OFF) and used normally.
Figure 4 - The red LED's runs from no. 1-9 (running light) and the blue LED flashes.
3.2 Turn ON / OFF
An integrated acceleration sensor allows the LEAKPEN to be controlled via movements / gestures.
To turn the LEAKPEN on from sleep mode (OFF), proceed as follows:
1. Shake the LEAKPEN once along any axis (Figure 5).
2. All LED's are turned on for 3s (Figure 6) to check their function.
3. Then the current battery voltage level is displayed on the LED's (see chapter 3.2.1 Battery voltage level display).
4. The LEAKPEN now switches to the measuring mode (ON) (see chapter 4.2 Measurement mode (ON).
To turn off the LEAKPEN:
1. Depending on the active operating mode, the LEAKPEN is set to sleep mode (OFF) in different ways (see chapter 4.2 Measurement mode (ON) and chapter 4.4 Bootloader mode).
2. To switch off the LEAKPEN completely, you must remove the battery (see chapter 3.1 Insert / replace battery).
3.2.1 Battery voltage level display
After turning on, the LEAKPEN first measures the battery voltage and displays it with the help of LED's. They flash 5 times. The number of LED's flashing simultaneously indicates the measured battery voltage according to the following table:
| Number of flashing LED's | Battery voltage (VBAT) in the range [V] |
| 0 | 0.0 V < VBAT ≤ 0.8 V |
| 1 | 0.8 V < VBAT ≤ 0.9 V |
| 2 | 0.9 V < VBAT ≤ 1.0 V |
| 3 | 1.0 V < VBAT ≤ 1.1 V |
| 4 | 1.1 V < VBAT ≤ 1.2 V |
| 5 | 1.2 V < VBAT ≤ 1.3 V |
| 6 | 1.3 V < VBAT ≤ 1.4 V |
| 7 | 1.4 V < VBAT ≤ 1.5 V |
| 8 | 1.5 V < VBAT ≤ 1.6 V |
| 9 | 1.6 V < VBAT ≤ 1.7 V |
| 10 | 1.7 V < VBAT |

3.3 Bluetooth Headphones - Pairing / Connecting
In order that data can be transmitted wirelessly using Bluetooth technology, the headphones has to be paired (registered) with the LEAKPEN.
To pair or connect headphones, the LEAKPEN must be in sleep mode (OFF) before it is switched on. After switching on, the LEAKPEN starts in measurement mode (ON).
The blue LED indicates the status of the Bluetooth connection.
Blue LED is off (Figure 9):
There is no Bluetooth connection
During the first 25 seconds after switching on, only a connection with already paired headphones can be established. During this time, the LEAKPEN does not search for new headphones.
Blue LED flashes for 5 seconds every 25 seconds (Figure 9):
There is no Bluetooth connection
As soon as the blue LED starts flashing for the first time, the LEAKPEN also starts searching for new devices to pair.
Blue LED lights up constantly (Figure 10):
Bluetooth connection is established.
3.3.1 Pairing new headphones
To pair new (unregistered) headphones, proceed as follows:
1. Turn on the headphones.
2. Put the headphones in pairing mode (refer to the headphones user manual).
3. Turn on the LEAKPEN from sleep mode (OFF) (see chapter 3.2 Turn ON / OFF).
4. Hold LEAKPEN and headphones close together, distance not more than 10cm (only necessary for pairing).
5. Wait until the blue LED lights up constantly, indicating that a connection has been established and the pairing process has been completed successfully.
3.3.2 Connecting already paired headphones
If the headphones have already been paired, the Bluetooth connection between the LEAKPEN and the headphones is established automatically. If the headphones are only switched on when the LEAKPEN is already in measurement mode (ON) and both devices are within range.
If the headphones are switched on before the LEAKPEN, the "PLAY" button must be pressed on some headphone models to establish the Bluetooth connection.
4. Operation
4.1 Operating modes
The LEAKPEN has 3 different operating modes.
- Measurement mode (ON) (see chapter 4.2 Measurement mode (ON))
- Sleep mode (OFF) (see chapter 0
- Sleep mode (OFF))
- Bootloader mode (see chapter 4.4 Bootloader mode)
4.2 Measurement mode (ON)
Measurement mode (ON) is the main operating mode of the LEAKPEN, in which it measures and displays the leak nois level and transmits them via Bluetooth to a connected headphone.
The LEAKPEN enters the measurement mode (ON) when it is shaken in the sleep mode (OFF).
The LEDs have the following functions in this mode:
The red LEDs indicate the level of the leakage noise signal (see chapter 4.2.1 Audio signal level indication).
The blue LED indicates the status of the Bluetooth connection
Blue LED is off (Figure 11):
There is no Bluetooth connection
During the first 25 seconds after switching on, only a connection with already paired headphones can be established. During this time, the LEAKPEN does not search for new headphones.
Blue LED flashes for 5 seconds every 25 seconds (Figure 11Figure 9):
There is no Bluetooth connection
As soon as the blue LED starts flashing for the first time, the LEAKPEN also starts searching for new devices to pair.
Blue LED lights up constantly (Figure 12):
Bluetooth connection is established.
In this mode, the LEAKPEN automatically returns to sleep mode (OFF) if there is no Bluetooth connection after 2 minutes. If a connection is established for longer, the LEAKPEN remains in this mode permanently; as soon as the connection is disconnected, the LEAKPEN returns to sleep mode (OFF).
4.2.1 Audio signal level indication
Leak noise level [dB] is indicated by 9 red LED's. Lit red LED's number displays measured audio signal level (Asl) in [dB] according to following chart:
| Number of lit LED's | Audio signal level (Asl) in the range [μg] |
| 1 (1 red LED) | Asl ≤ 40 μg |
| 2 (2 red LED's) | 40 μg < Asl ≤ 50 μg |
| 3 (3 red LED's) | 50 μg < Asl ≤ 63 μg |
| 4 (4 red LED's,Figure 13) | 63 μg < Asl ≤ 80 μg |
| 5 (5 red LED's) | 80 μg < Asl ≤ 100 μg |
| 6 (6 red LED's) | 100 μg < Asl ≤ 126 μg |
| 7 (7 red LED's) | 126 μg < Asl ≤ 158 μg |
| 8 (8 red LED's) | 158 μg < Asl ≤ 200 μg |
| 9 (9 red LED's, Figure 14) | 200 μg < Asl |
4.3 Sleep mode (OFF)
The LEAKPEN is in a sleep mode / power saving mode in which everything is turned off except the motion detection, so that the LEAKPEN can be switched on again with a shake.
4.4 Bootloader mode
The bootloader mode can be used to load firmware updates to the LEAKPEN via the Bluetooth connection.
Firmware updates are communicated and instructed by VONROLL.
The LEAKPEN always starts directly in bootloader mode as soon as the battery is replaced or intentionally removed and reinserted.
To show that the LEAKPEN is in bootloader mode, the LEDs have the following functions in this mode:
The red LED's show a running light effect, where they light up one after the other from No. 1 - 9 (Figure 15 and Figure 16).
The blue LED indicates the status of the Bluetooth connection.
Blue LED is blinking (Figure 15):
The LEAKPEN is visible to a Bluetooth Master device (PC, Smart Device, ...) and can be connected to it.
Blue LED lights up constantly (Figure 16):
Bluetooth connection is established.
The bootloader mode is terminated after 4 minutes if there is no Bluetooth connection and the LEAKPEN switches to sleep mode (OFF).
If no firmware update is required, the bootloader mode can be ended immediately with a shake and the LEAKPEN switches to sleep mode (OFF).
