NOTE Moving the locator further left and right will result in detecting smaller "ghost" signals either side of the main one. This is normal. Always be sure to locate all three peaks when locating the position of the Sonde as the ghost signals are not directly over the Sonde. The largest one is the true position. Moving forward and back across the Sonde will not detect ghost signals. Main Peak Ghost Peak Ghost Peak Now push the Sonde a couple of meters (yards) into the pipe. Stop and re-locate the Sonde. The direction of the Sonde can be confirmed by holding the locator vertically and rotating it on its axis until the largest signal is detected. The Sonde will then be pointing at right angles to the display. Continue pushing a short distance and relocating as the Sonde is pushed into the pipe. Do not be tempted to push the rod too far into the pipe without locating the Sonde as this will make finding the Sonde more difficult. Depth Measurements To take a depth measurement pinpoint the position and direction as previously described, pinpointing left/right, forward/back and also rotating on its axis. Hold the locator vertically over the position of maximum signal. Now press the "target" pushbutton. There will be a short delay before a depth estimate will be displayed. 33k NOTE The depth measurement is an approximation. Depth indications can be affected by field distortion caused by interference from in-band signals or metal structures such as re-bar. An aid to determining if the depth is correct is to repeat a depth measurement with the locator a known distance (for example 1ft./30cm) above the ground) and to note if the depth has increased by this amount. If it is different from what is expected treat the data as suspect. Changing Batteries 1. A low battery is indicated by the icon of the receiver display. 2. To replace the batteries, unscrew the end cap on the handle end of the VM-540. 3. Remove and replace both batteries with fresh 1.5V alkaline AA (LR6). 4. Replace end cap. Service Center Information If the equipment does not function properly, replace the batteries as described above. If the equipment still malfunctions, contact one of the Vivax-Metrotech Customer Service departments, or call the factory for the nearest authorized Vivax-Metrotech repair center.

Sondes are small transmitters that are inserted into non-metallic pipes and ducts for the purpose of locating its path. Sondes are also built into push camera and crawler camera systems. The lower sonde frequencies of 512Hz or 640Hz can be located in metallic pipes. The radiated signal from the Sondes are detected with the VM-540 receiver along with its depth of cover. The receiver can also passively detect the presence of 50Hz 60Hz which radiate from some live power, Cable TV or Telephone lines.

Allow the unit a few seconds to switch on. The frequency selected is shown on the display. If this is not the desired locate frequency (i.e. 50 or 60Hz) change as instructed below. NOTE The battery condition is indicated on the battery icon. Replace batteries if necessary. See Changing Batteries Section. Changing the Locate Frequency Press and hold the depth measurement/frequency selection pushbutton until the frequency menu is entered. The display will show the present frequency selected in large numbers in the center of the screen. Use the "+" or "" pushbuttons to select the desired frequency. Press the depth measurement/frequency selection pushbutton to re-enter the locate screen. Locating a Cable in the Power (50/60Hz) Mode Hold the locator vertically in the area that is required to be searched. Adjust the sensitivity of the locator by pressing the "+" or "" pushbuttons to keep the locator response on scale. Hold the locator in front of you in the orientation shown below. Sweep the locator left to right along the suspected route of the cable. As the locator approaches the cable the meter reading will increase. Pinpoint the position by detecting the largest signal. To confirm the direction of the cable, rotate the locator until the largest signal is detected. The direction of the cable is then directly ahead, pointing forward, away from the display. Continue to locate the cable along the route. Depth measurements are not possible in the power (50/60Hz) mode, if pressed by accident it will show N/A. WARNING The power mode is used to detect signals radiating from cables or services that are carrying a 50 or 60Hz load. It is possible for a cable to be live but not carry a load. In this case there may not be a signal to be detected. Similarly, if a cable is exactly balanced the resulting signal radiating from the cable may be zero and therefore not detectable. Do not use the VM-540 to identify cables if they are live. Always dig with caution. Sonde Locating Connect the Sonde to a suitable push rod. There is typically a 10mm thread on the end of the Sonde for this purpose. Switch on the Sonde and position it within the pipe access chamber leaving it still visible. Hold the locator above the Sonde at ground level. Adjust the sensitivity of the locator by pressing the "+" or "-" pushbuttons to keep the signal on scale. Rotate the receiver until the maximum signal is detected. https://manual-hub.com/
