WARNING

Read all safety warnings and in struc tions. Failure to follow the warn ings and instructions may result in electric shock, fire and/or serious injury.

SAVE THESE INSTRUCTIONS!

Work Area Safety

• Keep your work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate equipment in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. E quip ment can create sparks which may ignite the dust or fumes.
• Keep children and by-standers away while operating equipment. Distractions can cause you to lose control.

Electrical Safety

• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical shock if your body is earthed or grounded.
• Do not expose equipment to rain or wet conditions. Water entering equipment will increase the risk of electrical shock.

Personal Safety

• Stay alert, watch what you are doing and use common sense when operating equipment. Do not use equipment while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating equipment may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as protective gloves and clothing, dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the equipment in unexpected situations.

Equipment Use and Care

• Do not force equipment. Use the correct equipment for your application. The correct equipment will do the job better and safer at the rate for which it is designed.
• Do not use equipment if the switch does not turn it ON and OFF. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the batteries from the equipment before making any adjustments, changing accessories, or storing. Such preventive safety measures reduce the risk of injury.
• Store idle equipment out of the reach of children and do not allow persons unfamiliar with the equipment or these instructions to operate the equipment. Equipment can be dangerous in the hands of untrained users.
• Maintain equipment. Check for missing parts, breakage of parts and any other condition that may affect the equipment's operation. If damaged, have the equipment repaired before use. Many accidents are caused by poorly maintained equipment.
• Use the equipment and accessories in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the equipment for operations different from those intended could result in a hazardous situation.
• Use only accessories that are recommended by the manufacturer for your equipment. Accessories that may be suitable for one piece of equipment may become hazardous when used with other equipment.
• Keep handles dry and clean; free from oil and grease. Allows for better control of the equipment.

Service

- Have your equipment serviced by a qualified repair person using on ly identical replacement parts. This will ensure that the safety of the tool is maintained.

The last 2 seconds will flash and beep faster. After the last beep, the measurement is taken and the value is displayed.

Wireless Data Transfer

WARNING

Do not use the micro LM-400 as control device. Only use as a measuring device. This will reduce the risk of damage or injury in case of low batteries, malfunction or false measurement.

Do not allow operation in wireless mode to distract you from proper micro LM-400 use. Do not direct the laser beam towards other people. Make sure the laser is aimed above or below eye level. Laser beams may be hazardous to the eyes.

The RIDGID ^® micro LM-400 Laser Distance Meter includes Bluetooth ^® wireless technology allowing wireless data transfer to properly equipped smartphones or tablets running iOS or Android operating systems.

Measurements

The RIDGID micro LM-400 Laser Distance Meter has a measuring range of 229' (70 m) maximum. Use in bright sunlight may decrease the range of the meter. The reflective properties of the surface may also decrease the range of the meter.

Measurement errors can occur when measuring to clear, semi-permeable or high gloss/reflective surfaces such as colorless liquids (e.g. water), glass, Styrofoam, mirrors, etc. Applying a commercially available laser target plate to the surface may allow more accurate measurements.

Be aware of the measurement reference point setting, this can change measurements by up to 518 " (137 mm).

NOTICE Do not aim the laser at the sun. This can damage the meter.

Single Distance Measurement

1. Press ON/Measurement Button ( ) to activate the laser. The laser active symbol (*) flashes on the screen and a beep sounds.
2. Press ON/Measurement Button again to take a measurement. You may observe a slight delay and a clicking noise when making a measurement – this is normal.
3. The measured value is displayed.

Continuous Measurement, Max and Min Measurement

1. Press and Hold ON/Measurement Button ( 12 ) until the laser active symbol ( ) appears permanently on the screen and a beep sounds. Every further press of the button gives a measurement.
2. Press and Hold either ON/Measurement Button or Clear/OFF Button (ON/OFF) to stop continuous laser. The laser automatically switches OFF after 3 minutes of inactivity.
3. Press the Max-Min Button ( ) until the Max and Min Measurement symbol ( ) appears on screen.

4. Press ON/Measurement Button again to take the third measurement (height).
5. The result of the volume calculation is displayed in the summary line.

Indirect Measurements

Indirect measurements are used when a direct measurement is not possible. Indirect measurements are calculated from measurements of the hypotenuse and one side of a right triangle (triangle with a 90 degree angle). For instance, if calculating the height of a wall from the ground, measurements would be taken to the top of the wall (hypotenuse), and perpendicular to the line between the two measurement points at the wall base (side). From these two measurements, the distance between the two measurement points is calculated.

Indirect measurements are less accurate than direct measurements. For greatest accuracy with Indirect Measurements, hold the micro LM-400 in the same position (only changing angle) for all measurements. Make sure that the laser beam is perpendicular to the line between the measurement points when measuring the side of the triangle. All measurements need to be to points on a single straight line.

Using Two Points

Stake Out Measurement

Two different distances (a and b) can be entered into the instrument and can then be used to mark off defined measured lengths, e.g. in the construction of wall studs.

a b b

Figure 16 – Stake out Measurement

1. Press the Angle/Stake Out Button (☐) longer and the stake out function symbol (☐) appears in the display. The value (a) and the corresponding intermediate line flash.

2. By using (+) and (-), the value can be adjusted to suit the desired stake out distance. Holding down the buttons increases the rate of change of the values.

3. Once the desired value (a) has been reached, it can be confirmed with the (.) button.

4. The value (b) and the intermediate line flashes. Value (b) can be entered using () and () . The defined value (b) is confirmed with the () button.

5. Pressing the ON/Measurement Button ( ) starts the laser measurement. The display shows current measuring distance in the summary line. Moving slowly along the stake out line the display distance decreases. The instrument starts to beep at a distance of 0.1 m from the next stake out point.

6. The arrows (▲) in the display indicate in which direction the instrument needs to be moved in order to achieve the defined distance (either a or b). As soon as the stake out point is reached the beep changes and the intermediate line starts to flash.

Cleaning

Do not immerse the RIDGID micro LM-400 Laser Distance Meter in water. Wipe off dirt with a damp soft cloth. Do not use aggressive cleaning agents or solvents. Gently clean the display screen with a clean dry cloth. Avoid rubbing too hard. Treat the instrument as you would a telescope or camera.
