3.2 Re-levelingIf the unit is bumped or moved, the unit will automatically attempt to re-level itself. The Power On LED and the laser will blink during this process until the unit is level once again. The laser head will resume rotation.

On the job site, it may be necessary to prevent re-leveling in order to prevent inaccurate measurements by the opera-tor. The LMH’s Anti-Drift System (Section 3.3) is used for this purpose.

3.2.1 Axis Drive ErrorIf the LMH is set up or tipped beyond its self-leveling range of ±5°, the laser head will initially attempt to level; however, when the self-leveling limit is reached, the LEDs will blink, indicating an axis drive error (Fig. 2). Turn the LMH off, move the unit into a more level position, then turn the unit on again.

3.3 Anti-Drift System (ADS) (LMH, LMH-C, and LMH-GR only)By default the ADS feature is ON. The default setting of the ADS func-tion may be set to ON or OFF. When the unit is OFF, press and hold the MANUAL MODE (for LMH-GR, DOWN ARROW button) and then press the POWER button. Once the unit is on, turn the unit off for 15 Sec and then back on. ADS will not be the default when unit is turned ON. To make the unit return to ADS as default, repeat these instructions.When the LMH Series laser is fi rst turned ON, the ADS feature does not begin recording for 1 minute. This allows the instrument to be set up and adjusted. If after 1 minute, the unit is disturbed and the ADS light is fl ashing it is necessary to check any bench marks that have been made and ensure the proper "HI" (Height of Instrument). After the fl ashing ADS has been reset, by pressing the ADS button one time, you will have an additional minute to set and check your measurements. To turn ADS off press the ADS button once. This will put the unit into normal Auto Self-Leveling mode.

LMH-GR LMH600

For greater accuracy in grade applica-tions, precisely level the laser level before entering into GRADE MODE.

NOTE: The total percent grade possible is from a perfectly level base position. If the unit is mount-ed on a tripod head which is not perfectly level, then the grade percentage range capable would be reduced by the slope of the base, as this affects the tilt range of the laser head. For maximum grade range, ensure a level tripod head using a spirit level before mounting your unit.

Note: For the LMH-GR and LMH600, if the unit is bumped or moved while in Manual Grade mode, the unit will not re-level itself.unit will not re-level itself.

6. LMH SERIES CALIBRATIONYour LaserMark® level is a sealed unit and is calibrated to precise accuracies at the factory. However, a calibration check is recommended before the initial use of your laser, and then periodically from that point forward. Be sure to allow time (up to 30 seconds) for the unit to completely self-level before each check.

Please note the direction of the X and Y axes for the unit (Fig. 9). You will need to refer to this to complete the following steps.

6.1 Upright Position Peg Test (X axis)

1: To test the X axis, mount the LaserMark® on a tripod or a level, sturdy surface and place approximately 100 feet (30m) away from a wall. Face the left side of the unit (X- quadrant) to the wall.

2: Press the POWER button and allow the unit to self-level. Using the laser detector, locate and mark the position of the laser line on the wall (“A”, Fig. 10).

3: Loosen the LaserMark® from the tripod and rotate the instrument 180°. Ensure that the height of the tripod does not change, as this will affect your results. Secure and re-level the unit.

4: Again, locate and mark the position of the laser line on the wall (“B”). No adjustment is necessary if the vertical difference between A and B is less than 1/8" (3.5mm)

Repeat the above steps to ensure a correct reading. If the distance is greater than 1/8", you will need to calibrate the X axis (next refer to 6.1.2; for LMH600, refer to 6.2.1).


6.1.2 Upright Position Calibration - X axis (LMH, LMH-C, LMH-GR)

1: Keep the unit in its current position. Power Off the unit.

2: Power On the unit while holding the ADS button down. You will know if Calibration mode is activated when the Battery Low and ADS LEDs fl ash alternately. Then, the ADS LED will remain lit; this indicates that the unit is calibrating within the X axis (Fig. 11).

3: Locate the position of the two calibration buttons as shown in (Fig. 12), on theLMH-GR the UP and DOWN ARROW buttons change the axis increments. The upper button will produce a positive (+)

4: You must raise or lower the beam to center between points A and B on the wall (Fig. 13). The unit will react to “+” and “–” input within the X+ quadrant, with each single increment moving the beam approximately ±1/16" at 100 feet. If B is below A, increase the increment (+). If B is above A, decrease the increment (-).

5: The adjustments are automatically saved. You must now repeat the peg test (6.1) to insure you have made the correct calibration. Repeat calibration if necessary. You must allow time for the calibration change to be saved in memory.

6.1.3 Upright Position Peg Test and Calibration - Y axis (LMH, LMH-C, LMH-GR)

If you wish to test the Y axis at the same time as the X axis, simply keep the unit on from when you tested the X axis and rotate the unit 90° so that the front of the unit is facing the wall. Press the ADS button to turn the ADS LED off; you are now calibrating within the Y axis (Fig. 14); follow 6.1, steps 2 through 4.

If you are testing the Y axis at a later time than the X axis, mount the LaserMark® on a tripod and place approximately 100 feet (30m) away from a wall, with the handle (Y– quadrant) of the unit facing the wall; follow 6.1, steps 2 through 4.

Calibrate as in 6.1.2, adjusting “+” and “–” input as necessary within the Y+ quadrant (Fig. 15).If you are unable to calibrate the unit, or if the difference between points A and B is too great to calibrate within the range of the unit, please contact CST/Berger or an

authorized service center for assistance.

9. TROUBLESHOOTINGThe following information lists basic tests that can be performed to check the LMH in the event of poor performance.

Check Your Batteries: One of the most common causes of perfor-mance failures is due to defective or incorrectly installed batteries. Check to see if any batteries are installed backwards and correct if necessary.

• Never selectively replace batteries; always replace all of the batteries at the same time with new batteries. It is recommended, if possible, that the batteries be checked with a voltmeter or battery tester to confi rm proper voltage.

• Leaky batteries may have damaged the battery contacts in the battery box.

• Check to see that the battery tray is screwed tightly onto the base of the unit. Also, the fi t between the battery prongs and the batteries may need adjustment, as this fi t may vary over different brands of battery (especially Energizer™ brand, as they are larger in diameter, preventing a proper connection).

• Alkaline batteries are recommended for the best performance and storage life. Rechargeable batteries such as Nickel-Cadmium will provide performance, but are not as desirable due to their lower terminal voltage. Low cost standard Carbon-Zinc batteries may be used in emergencies, but they should be replaced with alkaline batteries when available.

Rechargeable Battery Pack: For maximum battery life, the battery pack must contain a full charge. The batteries will begin to perform optimally after fi ve full charges and discharges.

Unit does not rotate or self-level, or produces Axis Drive Er-ror: Reset the internal processor by turning power off and on again. You may also try removing the battery tray for 15 seconds to let the capacitor discharge, then replace the tray and try again.

If the unit rotates but does not self-level, be sure that the Anti-Drift System is turned off.


LMH Series Errors:

When an error occurs on the LMH Series, turn the unit OFF. Wait 15 seconds, then turn unit ON. If these procedures do not correct error, contact CST/berger.

4. OPERATION1: Mount the unit onto a sighting rod if you are using one. Turn on the unit by pressing the ON/OFF pad. The LCD symbols will momentarily fl ash (Fig. 1) and the “coarse” beam indicator symbol will remain lit and the audio signal will be on.

2: Expose the beam capture window of the laser detector towards the direction of the rotating laser.

3: Slowly move the laser detector in an upward and downward direction until the LCD beam indicator arrows appear and/or a pulsing audio signal is heard. Use the Beam Resolution feature to choose between the coarse/low setting, used for approximating level or for initial locating of the center level point, the medium setting, used for greater accuracy, and the fi ne/high setting, used for the most accurate pinpointing of level.

4: Move the detector upward when the low beam indicator light is lit (with volume on, a short pulsing audio tone is heard). Move the detector downward when the high beam indicator arrow is lit (with volume on, a long pulsing audio tone is heard). When the beam is level, the level beam indicator line will be lit and a solid audio tone will be heard.

If the detector is not struck by a laser beam after 5-8 minutes, the detector will automatically shut itself off to preserve battery life. Turn the unit back on using the power button.

5. SPECIAL FEATURESThis detector has a unique memory feature, which preserves the last position of the laser beam if the detector is moved out of the plane of laser light, as well as built in electronic fi ltering for bright sunlight and electromagnetic interference. Three distinct audio tones (high, on-grade, and low) assist targeting from a distance.

Features speaker Off, Loud (105 dBA) and Louder (125+ dBA), fi ne, medium, and coarse beam resolution settings, and front and back LCD displays. Seven distinct channels of information (Fig. 2) indicate the position of the detector in the plane of laser light. As you move the detector closer to the center, the arrows fi ll in to indicate the laser position.
