CHECKS AND ADJUSTMENTS
Checking and adjusting calibration
Checking cone error
Error Code
1
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 laser sensor in fine detection mode by pressing the On-Grade preci-
sion switch.
4
By using the laser 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 laser 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 7mm, adjustments are not needed. The difference
value is greater than 7mm, adjust the instrument as described in right. *
9
Check the X1 (handle) side as the same way.

Using the laser 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
By pressing the manual mode ON switch (laser beam moves up), or Power
switch (laser beam moves down), adjust the on-grade height of the beam until
it is precisely centered between the marks made in steps 3 and 5 .
7
Press the height alert OFF switch to memorize the new laser beam calibration.
The height aler t OFF lamp will blink. Power will shut off automatically when the
calibration memorization is complete.
[To calibrate the Y axis ]
1
Face the Y1 side of the instrument (handle side) toward a wall, press the
Power switch while pressing the height alert OFF switch.
Then the height alert OFF lamp will light, and manual mode ON lamp will blink.
2
Press the Power switch again. The auto leveling lamp will light.
3
Press the height alert OFF switch to calibrate the Y axis. The auto leveling
lamp will light.
4
Using the laser 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
By pressing the manual mode ON switch (laser beam moves up), or Power
switch (laser beam moves down), adjust the on-grade height of the beam until
it is precisely centered between the marks made in steps 4 and 6.
8
Press the height alert OFF switch to memorize the new laser beam calibration.
The height aler t OFF lamp will blink. Power will shut off automatically when the
calibration memorization is complete.
*If the difference value is greater than 60mm (2 3/8 inches), contact your
Topcon dealer.

[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 laser 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 laser 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.

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 laser sensor (ON).
5
Select the precision mode by pressing the
On-Grade precision switch.
6
Locate the on-grade position “---” by moving
the laser sensor up and down.
7
Mark the position of On-Grade index.
(Top of the Laser Sensor is 40mm [1 9/16"] from
index for offset marking.)

When using the Laser
Sensor with other
select Topcon lasers,
these symbols alert
user if laser batteries
are low or if laser has
been disturbed.
These symbols are
not active when used
with RL-H3CS.
Aligning Direction of Slope
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 illustra-
tion at right)
On-Grade position
Audio signal:Continuous beep sound
[Setting slope]
Manual mode can be activated
while the slope is set.
For information about Manual
mode ON/OFF, refer to "NOMEN-
CLATURE AND FUNCTIONS".
Check the beam often during
slope use for slope accuracy.
Check instrument calibration peri-
odically (see belo w).
