1. Product information

The tool is intended for use as a detector. It can detect ferrous metals (E.g. steel reinforcing bars), non-ferrous electrical conductive metals (E.g copper pipe, aluminium) and can detect the presence of an electrical field, making it possible to detect live electrical cable. As well as detecting the position of reinforcing bar accurately, it can also determine the depth of the reinforcing bar. It cannot determine the depth of any other material. The PS 20 detector can, within certain limitations be used to estimate or localise the position of a live electrical cable using the special live electrical cable detection function.

- automatic object recognition and display of detected reinforcement

- Detection of reinforcing bars within a defined minimum depth (ignoring any reinforcement that lie below this depth).

- Adjustment of detected depth for reinforcement containing impurities

- Detection of unshielded, live electrical cable.

1.4 Technical data

Reinforcement detection

All figures based on bar diameter of 12mm (0.5 in), round reinforcing bars, magentic permeability 85-105, concrete surface smooth and flat, reinforcing bars at right angles to direction of scan, no interfering influences.

Depth range for detection

Depth range for detection 0-100mm (0 - 4in)

Depth range for coverage depth measurement 10 - 80 mm

Accuracy of depth of coverage measurements

metric: from 10-30mm - +/-2mm from 30-60mm - +/-2mm +/-10% of depth from 60-80mm - +/-5mm +/-10% of depth imperial: from 0.4-1.18 in - +/-0.08in from 1.18-2.36 in - +/-0.08in +/-10% of depth from 2.36-3.15 in - +/-0.2in +/-10% of depth

Separation of reinforcement

Min 42mm (1.7 in) bewteen bars or 1:1.12, whichever is greater.

Non-ferrous metal detection

0 - 60 mm with 10 - 30 mm (tube-ø) (0 - 2.4 in with 0.4 - 1.2 in, ( tube-ø)

Localising live electrical cable

Will detect cable 100-240V 50/60Hz. Accuracy to which cable can be localised on the surface depends on a variety of factors such as air humidity, moisture in the material, elements close to the cable.

2. Safety precautions

2.1 Please read now!

These warnings should put PS 20 owners and operators in the position where they can recognize possible danger in advance and avoid it,

i.e. prevent it. The owner must make sure all

operators understand and follow these warnings.

2.2 Intended purpose

The Hilti PS 20 detector is intended to be used for the following purposes:

• detecting and depth of coverage measurement of steel reinforcement.

• detecting copper tubing and aluminum parts.

• localising live electrical cable.

The PS 20 detects electrically conductive ferrous and non-ferrous metals. The presence of small objects made from such materials or the presence of objects made from other materials cannot be ruled out.

Never attempt to open up the structure without first turning off the power supply.

In order to guarantee reliable results, the tool must not be used during large temperature changes. Allow the tool time to adjust to the surrounding ambient temperature before use.

Measurement and evaluation of the measurements should be performed by properly trained personnel.

Use as intended

Misuse

They:

• have read and understood the operating instructions

•are aware of the special features and limitations of the measuring principle used

• possess sufficient knowledge of reinforcement technology.

• Using the product without following the instructions in the manual.

• Using the product outside of application limits or technical specifications.

• Using the product before checking the minimum depth and offset function settings. When set incorrectly, these will result in misleading or incorrect measurements.

• Using in areas of electromagnetic anomalies. This may result in misleading or incorrect measurements.

• Using in areas where there is a danger of explosions.

• Using in the proximity of medical equipment. Use near such equipment may result in disturbances or failure of it.

• Do not immerse in water or use in very heavy rain.

• Opening parts of the product other than the battery compartment cover.

• Modifying and/or adding parts to the product.

• Using third party accessories not explicitly approved by Hilti.

• Using a damaged product or a product that returns results that are not plausible.

• Measuring with very worn or dirty sensor head cover or battery compartment cover.

• Measuring without sensor head cover or battery compartment cover

• Using without first testing the accuracy.

• Using to detect metal in humans or animals.

• Use of measuring results for purposes relating to safety without control measures and evaluation by qualified specialists. (e.g. civil engineers)

• Drilling very close to or on marked live electric cables or pipes.

• Drilling on marked reinforcement deeper than the depth displayed on the tool, also taking into account depth accuracy specifications.
