1 Checking and adjusting calibration
2 Checking cone error
Horizontal calibration of the laser beam can be checked by the user.
[Checking]
1 Set up a tripod approx. 50m (160ft) from a wall. Mount the instrument on the
tripod, facing the X1 side toward the wall.
2 Turn the instrument on and allow auto-leveling to complete.
3 Put the level sensor in fine detection mode by pressing the On-Grade precision
switch.
4 By using the level sensor, mark the center position of laser beam on the wall. (X1)
5 Turn off the instrument.
Loosen the tripod screw, rotate the instrument 180 degrees and re-secure it on
the tripod. The X2 side of the instrument faces toward the wall.
When rotating the instrument, avoid changing the height.
6 Turn the unit on again and allow auto-leveling to complete.
7 By using the level sensor, mark the center position of laser beam on the wall. (X2)
8 If the difference value of marked two laser beam heights (difference value of X1
and X2) are less than 5mm, adjustments are not needed.
The difference value is greater than 5mm, adjust the instrument as described in
right.*
9 Check the Y side as the same way.
To discontinue calibration the instrument, press the Power switch.
Perform the following check after completing horizontal calibration procedure.
[Checking]
1 Set up the laser centered between two walls approximately 40m (131ft) apart. Orient the instrument so one axis, either X or Y, is facing the walls.
2 Locate and mark the position of the rotating laser beam on both walls using the level sensor.
3 Turn off the instrument and move the instrument closer to wall A (1m to 2m /3 ft to 6 ft). Do not change the axis orientation of the instrument. Turn the
instrument on.
4 Again locate and mark the position of the rotating laser beam on both walls using the level sensor.
5 Measure the distance between the first and second marks on each wall. If the difference between each set of marks is less than 4mm (5/32 of an inch),
no error exists.

* If the difference value is greater than 4mm (5/32 inch), contact your Topcon dealer.
If the height alert OFF lamp blinks quickly and the power is not automatically turned off when pressing the
height alert OFF key to memorize the height, the height exceeds the adjustment range. Please contact
your local Topcon dealer.
How To Operate
1 Set the instrument to the tripod or smooth
surface.
2 Make sure instrument is roughly level.
3 Press power switch (ON).
4 Press power switch on level
sensor (ON).
5 Select the precision mode by
pressing the On-Grade

6 Locate the on-grade position “---” by moving
the level sensor up and down.
7 Mark the position of On-Grade index.
(Top of the level sensor is 40mm [1 9/16”]

Example Operational
Height Alert Function
When the instrument system detects a shock, this function informs
the operator of it.
• When the instrument’s installation status (height) is sharply changed
by the contact of the operator or the like, this function stops auto
leveling to keep the operation accuracy and informs the operator of the
situation. The three lamps blink at the same time as shown at the right.
• After 1 minute has passed since the auto leveling function was
activated and the laser beam was emitted, this function works.
• The height alert function does not work in the “Manual” mode.
Shock is given to the instrument.
The three lamps blink at the
same time and the rotary head
rotates at low speed.
Height alert status
[How to reset]
1 Turn off the power switch.
2 Check whether the instrument is installed correctly.
3 Turn on the power switch. Auto leveling starts again. After
auto leveling is finished, the laser beam is emitted.
4 Make sure that the laser beam is set at the correct height.
Then, restart the operation.

Aligning Direction of Slope
It is possible to set slope only in the X axis direction (refer to
“CHECKS AND ADJUSTMENTS”).
[1. Installation of the instrument]
When using the laser to set the slope, the laser must be
properly aligned so the slope axis of the laser beam is parallel
to the desired direction of slope.
The sight on top of the instrument is calibrated to the slope
axis of the laser beam. Follow the steps below to align the
laser to the desired direction of slope:
1 Establish a target line parallel to desired direction of slope.
2 Set up the laser over this line (drop a plumb bob from the
tripod mounting screw).
3 Rough align the instrument to the direction of slope. Make
sure it is properly oriented for the slope to be set.
4 Using the sight, position the instrument so the sight is
centered on the target. (see illustration at right)
Lamp Position
[To calibrate the X axis]
1 Face the X1 side of the instrument toward a wall, press the Power switch while pressing the height alert OFF key. Then the
height alert OFF lamp will light, and manual mode ON lamp will blink. (X axis is selected.)
2 Press the height alert OFF key to calibrate the X axis. The manual mode ON lamp will light. When auto-leveling finishes, the
laser beam will emit.
3 Using the level sensor, mark the on-grade height of laser beam on a wall.
4 Rotate the instrument 180 degrees to face X2 side toward a wall.
5 In the same way as step 3, mark the on-grade height of laser beam on a wall.
6 Press the slope key to make adjustment so that the laser beam height may be at the center between the positions of Step 3
and Step 5.
7 Press the height alert OFF key to memorize the new laser beam calibration. The height alert OFF lamp will blink. Power will
shut off automatically when the calibration memorization is complete.
The X axis adjustment is completed now.
[To calibrate the Y axis]
1 Face the Y1 side of the instrument (Control panel side) toward a wall, press the Power switch while pressing the height alert
OFF key. Then the height alert OFF lamp will light, and manual mode ON lamp will blink. (X axis is selected.)
2 Press the right Slope key once again. The auto leveling lamp will light. (Y axis is selected.)
3 Press the height alert OFF key to calibrate the Y axis. The auto leveling lamp will light.
4 Using the level sensor, mark the on-grade height of laser beam on a wall.
5 Rotate the instrument 180 degrees to face Y2 side toward a wall.
6 In the same way as step 4, mark the on-grade height of laser beam on a wall.
7 Press the slope key to make adjustment so that the laser beam height may be at the center between the positions of Step 4
and Step 6.
8 Press the height alert OFF key to memorize the new laser beam calibration. The height alert OFF lamp will blink. Power will
shut off automatically when the calibration memorization is complete.
