LMH SERIES OPERATION
3.1 LEVELING:
1. REMOVE THE LASERMARK LMH FROM ITS CASE. THE UNIT CAN
STAND ALONE ON A LEVEL, STURDY SURFACE OR BE SECURED
TO A 5/8”X11 SURVEYOR’S TRIPOD.
2. PRESS THE POWER BUTTON ONCE, AND ALLOW TIME (UP TO 60
SECONDS) FOR THE UNIT TO SELF LEVEL. THE POWER ON LED
(FIG. 1) AND THE LASER WILL BLINK DURING THIS PROCESS.
PLEASE NOTE, THE LASER HEAD MAY BEGIN TO ROTATE BEFORE
LEVELING IS COMPLETE. THE SELF-LEVELING SPEED IS
APPROXIMATELY ONE DEGREE PER 4 SECONDS.
3. AFTER SELF LEVELING, THE LASER HEAD WILL ROTATE AT 600
RPM (THE LMH 600 WILL ROTATE AT THE LAST SELECTED SPEED.
PRESS THE POWER BUTTON AGAIN TO TURN THE UNIT OFF).
(NOTE: FOR LMH-GR AND LMH 600 MODELS, SEE SECTION 4.3.2
(PAGE11)
3.2 RE-LEVELING:
IF 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 OPERATOR. THE LMH’S ANTI-DRIFT SYSTEM (SECTION 3.3)
IS USED FOR THIS PURPOSE.
3.2.1 AXIS DRIVE ERROR:
IF THE LHM IS SET UP OR TIPPED BEYOND ITS SELF-LEVELING
RANGE OF 5 DEGREES PLUS OR MINUS, THE LASER HEAD WILL
INTIALLY 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, ANDLMH-GR ONLY):
BY DEFAULT THE ADS FEATURE IS ON. THE DEFAULT SETTING OF
THE ADS FUNCTION 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 SECONDS 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
FIRST TURNED ON, THE ADS FEATURE DOES NOT BEGIN
RECORDING FOR 1 MINUTE. THIS ALLOWS THE INSTRUMENT TO
BE SET UP AND ADJUSTED. IF AFTER ONE MINUTE, THE UNIT IS
DISTURBED AND THE ADS LIGHT IS FLASHING IT IS NECESSARY
TO CHECK ANY BENCH MARKS THAT HAVE BEEN MADE AND
ENSURE THE PROPER “HI” (HEIGHT OF INSTRUMENT). AFTER THE
FLASHING 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.
3.4 GRADE MODE: SINGLE AXIS GRADE (LMH-GR AND LMH600NLY)
THE SINGLE GRADE FUNCTION IS IDEAL FOR GENERAL SITE
GRADING, CHECKING EXCAVATION, LANDSCAPING AND
DRAINAGE, AND MORE.

MANUAL GRADE MODE CAN BE ACTIVATED BY PLACING THE
AUTOMATIC LEVELING SENSOR IN THE OFF POSITION. PRESSING
THE MANUAL GRADE BUTTON WILL DEACTIVATE THE SENSOR.
THE SELECTED GRADE CAN BE AS MUCH AS A POSITIVE OR
NEGATIVE 10%, AND SET IN REFERENCE TO THE Y-AXIS OF THE
UNIT.
OPERATOR CAN USE ONE OF TWO METHODS TO GENERATE
SINGLE-AXIS GRADE (FIG. 4). METHOD 1: PLACE THE UNIT IN THE
MIDDLE OF THE TWO POINTS (A AND B) TO GET A HIGHER

UNIVERSAL LASER DETECTOR
INTRODUCTION
THE LASERMARK UNIVERSAL LASER DETECTOR AIDS IN
LOCATING AND TARGETING A VISIBLE OR INVISIBLE BEAM BY A
ROTARY LASER; PERFECT FOR USE IN OUTDOOR CONDITIONS,
WHERE SUNLIGHT AND DISTANCE MAY MAKE LOCATING THE
BEAM MORE DIFFICULT.
POWER
A 9-VOLT BATTERY WILL PROVIDE UP TO 3 MONTHS OF TYPICAL
USAGE. WHEN THE UNIT IS TURNED ON AND THE LOW BATTERY
SYMBOL REMAINS LIT, THE BATTERY SHOULD BE REPLACED.
OPERATION
1. 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 FLASH (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 UNITL 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
FINE/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.
SPECIAL FEATURES
THIS 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 FILTERING 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), FINE, 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 FILL IN
TO INDICATE THE LASER POSITION.
