The VM 500 Series are general-purpose locators that detect buried utilities in various situations. With a 50/60Hz passive power locating frequency and three active frequencies, the VM 500 series locators will meet the requirements of those wishing to detect the presence of active power cables and trace short ranges. The 1-Watt transmitter also has the additional frequency of 8kHz Fault-find, so it can be used to detect the presence of ground-to-sheath faults on cable when used with the VM-510 Stand Alone A-Frame fault locator.
The 1-Watt Transmitter applies a locate frequency by direct connection or induction. Optional Induction Clamps can clamp around a line and induce the locate signal onto it.
The VM-550FF Transmitter has one induction frequency; three direct connect and a fault-find frequency. The LED indicators on the transmitter show the frequency selected, output level, and battery status. An audio indicator beeps to advise the quality of the connection.
This one-watt transmitter can transmit the locate signal onto the target line three ways. By direct connection, if direct access to the line is available, by induction by simply putting the transmitter in induction mode and placing it over the target line with the induction arrow in line with it or by clamp mode and using the induction clamp to clamp around the target line.
The wide frequency range from the VM-550FF Transmitter makes this a very versatile transmitter. The 83kHz induction frequency makes it ideal for inducing the signal onto large diameter, direct buried iron pipes with bell and gasket connections, and for using the induction clamp around smaller pipes. The lower 512Hz and 8.192kHz are good for direct connection to trace cables, and the 83kHz direct connection is good for high resistance pipes or for use with pushrod camera systems to trace the deployed pushrod. The Fault-find frequency can be used with the VM-510FFL+ to locate cables and find ground to earth faults on them.
Packaged in a lightweight, rugged, ergonomic IP54 housing, the Transmitter provides consistent current output in direct connect, clamp, and induction modes. The Transmitter has protection against inadvertent connection to incoming voltages up to 240V. The Transmitter comes standard with direct connection leads, ground stake; clip-on carry straps, and D cell batteries.
The VM-500 Series receiver is a compact, general-purpose utility locator designed to detect buried services quickly and accurately. Built for everyday use across a variety of job sites, the VM-500 receiver offers the essential features needed for efficient power and signal tracing in a durable, easy-to-use package.
Equipped with a passive 50/60Hz power locating mode, the receiver can detect the presence of live power cables without requiring a transmitter. For more precise locating tasks, the receiver also supports three active frequencies, making it suitable for tracing utilities over shorter distances.
