Battery Warning Indicator

The Battery warning indicator will be shown for several minutes when the instrument is pow­ered ON or when the battery level changes.

Auto-leveling lamp

Flashing : Auto-leveling is in process. When automatic is leveling almost complete, the

flashing rate will be slow. The head will not rotate and the laser beam will not
emit during the auto-leveling process.

ON Solid: Auto-leveling is complete.

The rotary head is active and emits the laser beam.

To turn automatic leveling off

Note

• When BT-49Q is used, the blinking period will be short because of the charac­teristic of the battery.

• Laser sensor LS-70A/B can detect low power state of laser.

Battery is sufficient.

Dead batteries. Recharge the battery or replace the dry batteries with new
ones.(The laser will turn completely off after blinking for about five minutes.)
NOTE:Even if an AC/DC converter is connected at this time, blinking still con­tinues. Once the power is turned off, the battery remaining display will reset.

Continuous

To turn OFF the auto-leveling function (manual mode), press the Auto-Manual leveling con­trol pad twice in quick succession. The man ual mode indicator light will illuminate. The instru­ment can be positioned in any direction and the laser beam remains on and the head will
rotate.
IMPORTANT: In manual mode, the laser beam will not shut off if disturbed! To return to Auto­leveling mode, press Auto/Manual control pad once.

22

Operation

Scanning Mode

In scan mode, the laser rotates slowly, "searching" for the Magnetic Scanning Target. When
the target is properly placed in the beam path, the laser beam will scan rapidly back and forth
on the target and "track" the target as it is moved in its path.

1 Scanning mode is the default operating mode for the RL-VH3G/A/B. Each time the instru-

ment is turned on, it is in scanning mode. To change when operating, press the Scan
Mode Pad.

2 To initiate target scanning, place the Magnetic Scanning Target in the beam path with the

reflective strips facing toward the laser.

3 To stop scanning, remove target from beam path.

Continuous scan (Scan width can be "Drawn" and held for "Hands free" opera-

tion)

Place target in beam path and hold for a moment. The scanning beam will hesitate, then
start again. When the target is removed the beam will hold that scan automatically.
To change the scanning width, move the target left or right after the scan hesitates and the
scanning width will increase.

To cancel the "Drawn" scan simply:

Place the target for more than one second into the scanning laser beam again.

Note

• The target must be in the upright position for horizontal scanning use (magnet
on top).

Scanning hesitates
and starts again.

Move the target left or right with­in scanning, the scanning width
changes. The scan continues
without target for hands free
scan operation.

24

to use High power mode.

28

Setting Slopes

The laser beam can be sloped in either the X or Y axis (single slope) or both axes (com­pound slope).
Using the Slope Control pads (see page 12 ), the
beam can be electronically raised or lowered 5
degrees above or below the inclination of the instru­ment. This means that slopes up to 5 degrees can
be obtained if the instrument is set up on a level sur­face. For slopes greater than 5 degrees, the instru­ment must be manually positioned to within 5
degrees of the slope desired.

7 The rotating axis of the laser is directly over the center of the front floor mount leg in its

stored position. Therefore the beam will rotate forward of the control point when the laser
is rotated on the front floor mount leg.
The Off-set however is constant (59mm) from the rotation axis to the beam, so marking a
control point 59mm behind the actual control point will make set-up easy and accurate.

Checking and Adjusting

There are three areas of performance the user should check periodically.

Horizontal Calibration
Horizontal Rotation Cone
Vertical Calibration

The Horizontal Calibration and Vertical Calibration can be easily check ed and, in most cases,
adjustments can be made by the user . Horiz ontal Rotation Cone can be chec k ed b y the user,
if an error is found, adjustments must be made by a Topcon service facility.

Attaching the calibration decals

Before calibration, attach the calibration decals to the instrument as shown below. The cali­bration decal shows the calibration function of certain control pads on the control panel.
