Instruction Manuals

Quick Reference Guide is intended to provide a quick referenc e in the
field.For ease of use in the field,the following Quick Reference Guide
booklets are provided in the carrying case.

1. Basic procedure

2. PowerTopoLite Operating procedure

The complete instruction manuals are contained on the CD that is
attached to each V-325DN.

This guide uses the symbol “

xN

”as an expression of repeating times
of key operation. For example. “ x2” means that [ESC] key is
pressed two times.
The symbol “+”expresses that multiple keys are pressed simultaneously.

PRECAUTIONS REGARDING SAFETY

Before using this product, be sure that you have thoroughly read
and understood the instruction manual that is included in the

attached CD-ROM to ensure proper operation.

WARNING

Solar Observation

Never view the sun directly using the telescope as this may result
in loss of sight.

Laser Safety

V-325 is Class IIIa (3R) Laser product.
Do not look into the laser radiation aperture directly as this
may result in damage to your eyes.

9

Electro-Magnetic Compatibility (EMC)

This instrument complies with the protection requirement for
residential and commercial areas.If this instrument is used close to
industrial areas or transmitters,the equipment can be influenced
by electromagnetic fields.

Risk of Explosion

Do not use this product in a location where there is coal dust, or
near flammable material as there is a risk of explosion.

USAGE PRECAUTIONS

Target Constant

Confirm the Target Constant of the instrument before measurement.

Reflectorless and Reflecting sheet

The reflectorless measurement range may vary depending on the
target and surrounding brightness.
In case the reflectorless measurement results in low accuracy,
perform the distance measurement by Prism.

Battery & Charger

Use the battery charger that is suitable to the battery you are using.
If water should happen to splash on the instrument or the battery,
wipe it off immediately and allow it to dry in a dry location.

3.Basic Field Checking Procedures

Checks and Adjustments should be performed before and during
measurement.

3.1 Laser Pointer

To activate the laser pointer:

Check if the projected laser spot points at the same position that is
aimed by the center of the cross-hair line of the telescope.
To adjust the laser pointer:Consult your local dealer.

3.2 Warning and Error Messages
Warning Message

Meaning What to do

Displayed when the instrument is
tilted beyond the vertical compensation
range (±3’) in case automatic compen­sation is selected.This message may be
temporarily displayed if the instrument
is turned too fast.

The input data exceeds the allowable
range.

• This message is displayed if a long
distance which is a far beyond
measurable distance of V-325DN
series is measured with a wrong
target mode.
Please select a correct target then
measure.
If a wrong target is selected,a
correct distance cannot be
measured.

• The measurement distance is less
than 1.5m in Reflector sheet mode.

• The measurement distance is less
than 1.5m in Prism mode.

• Under too strong sun light.

• Unstable light value owing to
shimmer or obstacles.

• Target and Prism do not face
the instrument.

• Target and Prism are not correctly
sighted.

• Measurement range is over in
Reflectorless mode.

• Sufficient signal does not return by
sighting sharp edge etc. at
Reflectorless mode.

Re-level the instrument.
Repair is needed if the
message is displayed
when it is properly
leveled.

Press the [ESC] key and
enter the correct data.

Select the correct target
mode.

Select a longer point,
or use a tape measure.

Change the object
that has much better
reflectivity,or wait until
the sun activity
has weakened.

Error Message Meaning What to do

3.3 Atmospheric Correction

The speed at which light travels through the air varies depending
on the temperature and atmospheric pressure.The V-325DN is
designed to measure distances at the speed of light in order to
measure accurately, atmospheric correction needs to be used.
The instrument is designed to correct for weather conditions
automatically if the temperature and pressure are input.
Correction is then carried out based on the following formula.

Calculation formula:
K= (276.26713 -

78.565271 • P

) x10

-6

K:Atmospheric Correction Constant
P:Atmospheric pressure (hPa)
t:Temperature(°C)
Distance after Atmospheric Correction D = Ds (1+K)
Ds:Measured distance when no Atmospheric Correction is used.

4.Digital Camera

4.1 Turning the camera On and Off

To set the camera On:
To set the camera Off: View 1/3 Screen
NOTE: The part of function key assignment for the display panel

will be changed depending on power ON/OFF of the camera.

4.2 Taking pictures

Take a picture in the View mode ,which is the first display when the
camera is activated.

4.2.1 Taking pictures and measuring distance at the same time

Sight the target by the telescope.
To measure the distance :

4.2.2 Taking pictures without measuring distance

Aim the target when using the telescope or the camera display.

To take a shot :

NOTE: A Point mark can be displayed on each image.This function

can be pre-set by selecting ON/OFF from the setting menu.

4.3 Playing back images

The images can be checked by ReView mode.

To cancel ReView mode:

NOTE: In the event that the aimed point and the Point Mark do not

coincide.Please refer the chapter of "basic procedures" on
the instruction manual for adjusting camera axis using
Current Center Mode.
