Hi. My name is Phil Tromley for the RIDGID® tool company and today I'm gonna walk you
through our 10 watt line transmitter the ST-510. For sake of comparison,
I brought its little brother, the 305, which was a 5 watt unit which is all you'll ever need.
But for those individuals doing larger diameter pipe line work, water supply cast pipe, etc.
this is the tool of choice. Twice the power, twice the capability of pushing a signal down the line.
First things first, requires 8 d cell batteries, which conveniently fit in to the back of the unit.
So we'll walk you through the features of this unit. Basically terminal lead,
these are approximately 50' long, stretch out forever. So very convenient.
And again, no polarity. One to the ground, one to the utility. If we go over the dash,
here we got our controls. The on/off button, volume control, the menu button which gives
you the capability of dialing the frequency to competitors units which is very convenient.
The inductive move button, which we'll discuss a little later. We have the up
power key and the down power key and these are the frequency selections. Again, four buttons,
five frequencies. Let's turn it on and see what it looks like nice.
Nice LCD dash assembly and if you take a look white LED indicating we're at 128
Hertz. Other choice, one kilohertz. Other choice 8 kilohertz. Other choice 262 hertz
European frequency which we can use here, and 33 thousand hertz. So the way the inductive
mode would work is that you would be carrying this out in a field, so obviously above-ground,
in the hope that you can basically find the conductor below ground, like a pipeline etc.
So in this case, just illustrate this pipe with a piece of conduit. And what would happen is that
the signal from the north and south pole would basically drop below ground, concentrate where
there's a conductor, and come back and whoever is on the locator about 30' away could basically
determine if he's reading the signal through the ground. So that's a quick look an inductive.
So we're outside and we're just gonna kind of show you how to set this up. It's pretty
simple. In this instance, we're going to use the ground rod that's supplied.
You look around any paved area etc. look for the grass that grows between the cracks
and that should give you the capability to plunge this with sufficient contact
area to hopefully create a good ground.
So again, the rule remains the same. We clip to the ground rod first so that way
if there is any live current on the utility 250 volts it's capable. Clip to a vise grip,
in this case the utility has no tracer wire and if we have a circuit the dash should
confirm the resistance in the circuit and basically the power. We can hear it beeping.
We are here just to kind of illustrate the use of the power setting on the tool which will either
maximize your battery life or for that matter push the signal further down the conductor. If
you take a look at our dashboard it's set at the lowest setting. By pressing the up arrow,
it's going to incrementally bring it up to another setting, 25 milli amps.
We can again press it again and bring it to 10 milliamps and so on. And so effectively,
depending on the resistance in the circuit, it will determine the maximum amount of amps required
to operate the tool. But this is basically how you can maximize your battery life or
for that matter maximize pushing the signal down through the conductor. That's the power control.
So we're back inside and what I want to just discuss real quickly
is why do we provide you 5 different frequencies to operate the tool. The
answer simple. Depending on the quality of the sub-tree, the conductivity of the soil,
and the conductivity of what you're trying to trace, be it an exposed tracer wire,
a large diameter cast pipe, an underground pipeline that's been in the ground for 50 years.
That's why we provide you different choices of frequencies. And again the logic is the same.
Basically a 128 Hertz is the lowest frequency energy that we have which the tool is set at
right now. Then we could step it up to one kilohertz which is a thousand Hertz. Step it
up again to 8 kilohertz or 8,000 Hertz and go for 33,000 Hertz which is obviously a lot more coiled
energy in that spring if you imagine 33,000 folds in the same distance. And of course we
have 262,000 which is very high energy but however dictates a lower wattage because of the FCC rules.
So again, who would be the typical end-user for this unit? It would be someone doing pipeline
or water supply, cast iron, large diameter work going between hydrants and services of the like
you know with large exposed pipe diameters. This would be the tool where the additional
10 watts power capability would make your locates and your life easier. Thank you.
