Frequently Asked Questions - MR10 RIDGID

How to turn the MR10 detector on and off?

Press the On/Off button to turn the device on. The display lights up and medium amplification is automatically selected. To turn off, press the same button again.

How to replace the batteries of the MR10?

Turn off the device, unscrew the battery compartment cover, remove old batteries if present, install six new AA alkaline batteries respecting polarity, then screw the cover back on. Use batteries of the same type and do not mix new and used batteries.

What to do if the device does not detect any object?

First check the battery condition. Make sure you are in an area containing ferrous metals (cast iron, steel). Hold the detector 1 to 3 inches (2.5 to 7.5 cm) above the ground and sweep slowly. If no signal, increase amplification with the +/- button. Keep personal metal objects (keys, tools) away as they can interfere with detection.

What is the maximum detection depth?

The depth depends on the mass, distance, and orientation of the object. The detector can locate large buried objects (such as valves or markers) at several tens of centimeters, but there is no precise guaranteed value. Probing remains the only way to confirm exact position.

Can I use the MR10 underwater or in snow?

Yes, partially. The lower 61 cm of the tube (below the display) can be immersed in water or pushed into snow. Never immerse the display screen or control panel as they are not waterproof.

How to interpret the displayed polarity?

The screen shows a polarity indicator (+ or -). Long thin objects (pipes, rods) often have a pole at each end. A vertical object has only one pole. Polarity can help isolate a target. Polarity switching at pipe junctions is normal.

How to use the AUTO NULL function?

In the presence of persistent magnetic fields (fences, metal buildings), stay in that area but away from targeted objects, then press the AUTO NULL button. The absolute signal returns to zero, eliminating interference. To exit this mode, turn the device off and on again.

What types of metals does the MR10 detect?

The detector is designed for ferrous metals (cast iron and steel) that emit a magnetic field. It does not detect non-ferrous metals (copper, aluminum), nor wood, plastic, concrete, stone, ice, snow, water, or soil.

How to clean the MR10 detector?

Use a soft cloth slightly dampened with water. Do not rub too hard and do not use harsh chemicals. Never immerse the device in water. Clean regularly to facilitate inspection and maintain a good grip.

Where to find spare parts or get the device repaired?

Contact the nearest Ridgid distributor, visit www.RIDGID.com or email [e-mail] (US/Canada). Repairs must be done by an authorized repairer using original parts.

-stones, snow, ice, water and the ground itself. These have no effect on the performance of the locator (unless they contain ferrous or magnetic materials).

This manual gives general instructions for use of the locator. Each specific use will be different and depends on the exact set of circumstances present. Locating is aided by applying good practices prior to turning the magnetic locator on. Use visual cues and past history to start your locate in an appropriate spot.

Locator General Considerations

The MR-10 Magnetic locator detects magnetic fields. It is specifically intended for use detecting the magnetic field from ferrous materials (iron based materials such as cast iron and steel) generated in the presence of the earth's magnetic field. It will also detect magnetic fields from magnets, electrical fields and other sources.

The magnetic field from ferrous materials depends on the size, distance and orientation of the ferrous part to the locator. In general,

• the larger the ferrous metal, the greater the signal.
• The closer the ferrous metal, the greater the signal.
• The signal is greater near the ends of long, slender parts, such as pipes or rods.
• The signal is greater near the edges of flat parts such as plates.

There can be multiple sources of magnetic fields in an area. This includes items on your person, such as steel toes in boots, tools in pockets, etc. These can interfere with the locating process.

Magnetic fields can be distorted and interfered with. Because of this, the locator cannot be certain to locate specific items, and cannot determine the exact distance to the item. Exposing the source of the magnetic field is the only way to verify its existence, location and depth.

Utilities (such as natural gas or water piping, electric lines or wires) may be present in a given area. Follow local guidelines and one call/call before you dig service procedures prior to digging. Do not use this locator for locating electrically generated magnetic fields.

The locator will not find and is not affected by the presence of nonferrous objects, such as copper, aluminum, wood, plastic, concrete,

General Locating

1. Turn ON the magnetic locator by pressing the ON/OFF button. The screen will turn on.

The gain level is set to medium range by default.

1. Hold the magnetic locator 1"-3" (25 - 75mm) above the ground.

2. Sweep from side to side while walking at a normal pace. Observe the Signal Strength and listen to the audio tone. The signal strength will be highest and audio tone rise in pitch when the locator is pointing in the direction of a magnetic field. The signal will fall as the locator moves away from a magnetic field. Move toward higher signals.

If there is excessive magnetic signal and it is difficult to determine the highest signal, increase the locator height from the ground. This will minimize the magnetic signal from smaller items (Figure 6).

SIGNAL ABOVE GROUND SIGNAL AT GROUND SMALL BOLT CURB STOP

Figure 6 – Raising the Locator Minimizes Unwanted Signals

1. Continue toward higher signal strength - audio tone will rise in pitch with signal strength. When nearing the signal source, the bar graph may go off scale and audio tone will be at maximum pitch. If this happens, decrease the gain by pressing the Gain Down Button and repeat the process for better location. See "Polarity" and

"AUTO NULL" sections for information to improve locates. See Figures 7 and 8 for locating signal patterns.

Specific Locating

1. When the signal source has been generally located, move the locator to the vertical position.
2. Lower the gain if necessary.
3. Move the locator in a cross pattern (Figure 9).

The signal bar graph and audio tone will be highest when locator is over the target.

Polarity

The MR-10 Magnetic Locator includes a feature to determine the polarity of a magnet. Polarity can be used to help better identify an object during locating.

All magnets have two poles (+ and -, positive and negative), and those poles generally follow the shape of the object. For instance, a long, thin object such as pipe will typically have a pole at either end. The orientation of the object being located may be implied through the use of polarity.

A long thin ferrous object oriented vertically, such as a pipe, survey spike, rebar or nail will show a single pole, either positive or negative. A long thin ferrous object oriented horizontally, such as a pipe or rebar will show a strong reading at either end (pole) with little signal in between the poles. One end will be positive and the other negative. See Figure 8. When locating along a run of pipe, you may see the polarity reading flip from positive to negative or vise versa at the joint. This will only happen if the pipe ends are isolated (not connected) to each other.

Polarity can often aid the user when identifying a target from non-targets as the polarity may flip from positive to negative

AUTO NULL

In environments with a persistent magnetic signal, such as along a chain link fence or a metal building wall, the Auto Null feature allows the locator be re-zeroed to eliminate the readings from that persistent magnetic signal.

While in the persistent magnetic field (but a - way from the objects that you are trying to locate), press the AUTO NULL button. The Absolute signal strength should reset to zero (Figure 10). Continue locate as before.

To turn off Auto Null and reset the unit to normal settings and sensitivity, cycle the power OFF, then ON.
