Function

Wöhler VIS Ø 40 mm and Ø 26 mm camera heads are equipped with a transmitter coil that transmits signals at a frequency of 8.9 kHz or 9.2 kHz (depending on the region)
Three coils inside of each handgrip of the Locator measure magnetic fields. When the user holding the Locator approaches the camera head the measured magnetic field gets stronger.
By calculating the difference in intensity of the signals received from the different coils, the Locator is able to indicate in which direction the camera head is located as seen from the Locator.
A cursor in the display and an acoustic signal enable the user to locate the exact position of the camera head in the pipe.

Activating the battery

Before using the Locator for the first time activate the battery by pushing the locking switch carefully to the right. Use a tapered object.

Charge level and charging the rechargeable battery

The charge level of the rechargeable battery is indicated in the top right of the display.

NOTE: The Locator powers off automatically when the battery charge is too low. It is possible to power the Locator on again as soon as a charger is connected.

If the rechargeable battery symbol is not filled,] proceed as follows to recharge the battery:

Plug the micro-USB connector of the USB cable – included in the scope of supply – into the USB port (Fig. 1, position 6), then connect the power pack to the mains power supply (The USB cable is a standard micro-USB cable)
The lower part of the light framing the ON/OFF key flashes red while the battery is being recharged.
The rechargeable battery is fully recharged when the red LED lights up continuously.
During the charging process, a dynamic battery icon is shown in the display (in the upper right corner when the locator is switched on, in the middle when switched off.)
The battery is fully charged when the battery symbol appears filled with 3 bars.

Operating the Locator

CAUTION: Protect the Locator against moisture.

NOTE: If possible, power off any electronic/electrical devices in the immediate area where you intend to use the Locator as they can affect the magnetic field.

Powering the Locator on and off

To power on the Locator, briefly press the On/Off key (Fig. 1, position 2).
When the Locator is powered on, the top part of the light framing the On/Off key lights up green.
The display powers up after about two seconds.
To power off the Locator, press and hold the On/Off key for about one second.

Selecting the frequency

Before locating the camera head, the user must select which frequency the locator should search for.
Make sure you know the frequency of the transmitter of your camera head. (Operating Instructions of the camera, chapter “Specifications”)

The locator offers the following options: 8.9 kHz, 9.2 kHz and Auto If “Auto” is selected, the locator automatically determines the frequency of the transmitter of the camera head.

NOTE: If the “Auto” function has been selected, the locator can only locate the camera head; if it is within 1 m of it.

The selected frequency is shown in the upper right corner of the locator display, see Fig. 2, Part 8.
Proceed as follows to make your selection:
With the locator on, briefly press the On/Off button to enter the Frequency-Selection-N Menu.
Use the -/+ buttons to select the frequency.
Briefly press the On/off button again to confirm your selection.

Adjusting the volume / using headphones

An acoustic signal provides a clear indication of the distance between the Locator and the camera head. The closer the Locator gets to the camera head, the more intensive the signal becomes.

Press the + key to increase the volume.
Press the – key to reduce the volume.

The acoustic signal is only available through the headphones as soon as you connect the headphones to the headphone socket of the Locator.

Localizing the camera head

NOTE: It is possible to switch off the transmitter in the camera heads VIS 250 and VIS 350. When working with this system, make sure that the transmitter is switched on before beginning the localizing procedure (please refer to the operating manual Wöhler VIS 200/250/300/350, chapter “Making settings via the menu”. The transmitter in the camera heads Wöhler VIS 200/300 is permanently switched on.

Localizing visually

The position of the transmitter is depicted on the virtual plane immediately after the Locator is powered on.
The intensity indicator indicates the strength of the signal being received on a scale between 0 and 100.
The longitudinal axis of the virtual plane symbolizes the distance to the transmitter from the Locator.
The direction in which the Locator needs to be guided to reach the position of the camera head is also indicated on the virtual plane.
The position of the camera head has been located when the cursor is positioned directly above the Locator icon.

Localizing acoustically

At the same time, the intensity of the acoustic signal increases as the Locator gets closer to the transmitter.
The pitch of the tones gets higher and they are repeated in increasingly rapid succession.

Marking the position of the camera head
Once the camera head has been localized, it is possible to mark its position using the yellow lithographic chalk supplied.

Push open the cover of the compartment on the front of the housing (Fig. 1, position 7).
Take out the lithographic chalk.

Working with the telescopic pole

The telescopic pole is a useful assistant when localizing the camera head concealed in the ceiling or in pipes deep in the ground or high up.

Operating the Locator

The rear of the Locator: the arrow points towards the slot used to secure the telescopic pole.

To be able to hold the Locator flat against the wall, slide the straight part of the holder (1) into the slot on the rear of the Locator.
To be able to view the display as you work, slide the angled part of the holder (2) into the slot.
Undo the clamp (3) on the telescopic pole.
Pull out the telescopic pole to the desired length and then tighten the clamp (4).
