distance is set by attaching the self-centering feet for the pipe size to be
laid (The 150 mm, six inch feet are standard. All other sizes are optional.)
or by adjusting the height of the piper on the Trivet Mount Assembly.

• Line - The position of the laser beam relative to the centerline of the pipe
to be laid. Set the line by aligning the laser beam with the next manhole.

2.8 Alignmaster (Piper 200 only)

!
!

a

b

c

Alignmaster is a function of the Piper 200 only.

When the Alignmaster button (a) is pressed, the Piper will begin a
search routine to find locate and stop on the target. This funciton is
normally used for second day setups to quickly find the beam in the
previous day’s work.

Procedure for using Alignmaster:

• Position the target assembly in the end of the last piece of pipe with the
two reflective strips on the inside of the pipe, facing the laser.

• Roughly align the laser beam in the pipe to the target assembly

• Press the ALIGNMASTER button (a). When pressed the laser will scan left
and right until the target is found. While searching the main operating
screen is replaced with a blinking target (b) indicating that Alignmaster is
working.

• If the search routine is successful, the target will remain on the screen for
an additonal five seconds (not blinking).

• The beam can now be fine positioned to the center of the target using the
LEFT or RIGHT arrow buttons (c) on the laser or the remote control.

e

If the Alignmaster function cannot find the target, a question mark will
appear next to the target (d) to indicate “target not found”. This screen will
appear for two minutes or until another button is pressed. The line position
will then return to its original position.

• The Alignmaster routine can be interrupted at any time by pressing the
Alignmaster button a second time. The line position will return to its orig­inal position.

• If the ambient light conditions are too bright for the Alignmaster function
to operate properly, the target will be shown with a question mark and a
sun icon.

!

!

When the Alignmaster button is pressed the beam will appear to dim.
This is normal. The beam is actually pulsing at a very rapid rate to better
control the recognition of the target.

Alignmaster is designed to work at distances greater than 10 meters
(30 feet). Demonstrations or usage at shorter distances may not find
the target.

4 Refraction

• Refraction happens when layers of air with varying degrees of tempera­ture and humidity deflect light as it passes through it.

• Layers of air in a sewer pipe can refract a laser beam, causing it to bend
downward or produce a “dancing” effect as the beam passes through to
the target.

• Refraction is especially noticeable during hot or humid weather, but may
also occur in extrremely cold conditions when warm air from a newly
opened trench mixes with the colder air.

• In these conditions, Leica Geosystems strongly recommends the use of a
blower assembly to reduce or eliminnate the effects of refraction. A
blower mixes the different layers of air temperature and density inside a
sewer pipe, thereby creating a uniform medium for the laser beam to pass
through.

4-1Piper 100/200Refraction

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

!

Allow the blower to operate for at least 10 minutes before aligning the
next pipe.

• Connect the blower to a power source, normally a 12-volt battery.

• Position the blower. Make sure that the air intake for the blower is not
blocked. If possible, position the blower so the temperature of the air it
draws in is approximately the same as the air inside the pipe.

• Determine whether to attach the nozzle to the end of the blower. If the
pipe is less than or equal to 250 mm (10 inch), use the nozzle. If the pipe
is greater than 250 mm (10 inch), you do not need to use the nozzle.

• Use clamps to attach the blower hose at the beginning of the pipe where
the laser is located. Position the end of the hose at a 60° angle to force
the air to swirl as it travels through the pipe.

• Apply power to the blower and let it operate.

5.1 Target Assembly

!

The Target Assembly provide a visual reference for locating the laser
beam and aligning the pipe.

• The target assemblies have a special holographic material applied to them

b

that enhances the beam visibility even in bright light conditions.

• The two target inserts have markings on them for centering the crosshair
in the center of various sizes of pipe. The small target insert is standard
with the target assembly. The large target insert is sold as an optional

a

accessory.

Small Target Insert (a) – 150, 200, 225, 250 and 300 mm (6, 8, 9, 10, and
12 inch)

Large Target Insert (b) – 400, 450, 500 and 550 mm (15, 18 and 21 inch)

• The reverse side of each of the targets has two retro-reflective strips.

c

These strips are used with the Alignmaster feature. When the ALIGN­MASTER button is pressed, the beam scans from side to side and until it
detects the reflective strips then stops between the them.

• A small, 100 mm (4 inch) self-centering target (c) is available for these
smaller pipes.

Use the Leica Geosystems battery and charger recommended by Leica
Geosystems to ensure the correct functionality of the instrument.

5.5.3 Charging the Battery

• Follow the instructions received with your charging
unit to ensure proper charging of the battery.

Primary Use / Charging

• The batteries must be charged prior to using it for
the first time because it is delivered with an energy
content as low as possible.

• For new batteries or batteries that have been
stored for a long time (> three months), it is effec­tual to make only one charge/discharge cycle.

• For Li-Ion batteries, a single discharging and
charging cycle is sufficient. We recommend carrying
out the process when the battery capacity indi­cated on the charger or on a Leica Geosystems
product deviates significantly form the actual
battery capacity available.

5-9Piper 100/200Accessories

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

• The permissible temperature range for charging is between 0°C to
+40°C/+32°F to +104°F. For optimal charging we recommend charging the
batteries at a low ambient temperature of +10°C to +20°C/+50°F to +68°F
if possible.

• It is normal for the battery to become warm during charging. Using the
chargers recommended by Leica Geosystems, it is not possible to charge
the battery if the temperature is too high.

Operation / Discharging

• The batteries can be operated from -20°C to +55°C/-4°F to +131°F.

• Low operating temperatures reduce the capacity that can be drawn; very
high operating temperatures reduce the service life of the battery.

It is the responsibility of the user to follow operating instructions, and
to periodically check the accuracy of the instrument and work as it
progresses.

The Piper is adjusted to the defined accuracy specification at the
factory. It is recommended to check your laser ofr accuracy upon
receipt and periodically thereafter to ensure accuracy is maintained. If
your laser requires adjustment, contact your nearest authorized service
center or adjust the laser using the following procedure.

Do not enter this mode or attempt adjustment unless you plan to
change the accuracy. Accuracy adjustment should only be performed by
a qualified individual that understands basic adjustment principles.

This procedure is easier when performed with two people, on a rela­tively flat surface and when using a trivet assembly. Refer to illistration
on the previous page.

Checking Level Accuracy

• Set up the Piper on the trivet assembly, level tihe Piper with the trivet feet,
and set the grade counter to 0.000%,

• Set up a transit or automatic level as shown in the illustration approxi­mately 30 meters (100 feet) from the Piper..

• Take grade readings approximately 30 meters (100 feet) on either side of
the transit. These readings beome A1 and A2.

• Stand at the grade rod and note where the laser beam strikes the rod.
Takes readings B1 and B2.

• Subtract B1 from A1 to determine C1, and B2 from A2 to determine C2.
If C1 and C2 are the same, the Piper is accurately adjusted.
If C1 and C2 are not the same, continue with the accuracy adjustment

procedure.

!

Line and Grade should be checked after the first 7.5 to 15 meters (25
to 50 feet) of pipe is laid to ensure the pipe is at the proper grade and
line.

Checking Line and Grade

• Set up a transit or automatic level as shown in the illustration.

• Take grade readings at the ends of the pipe using a grade rod.

7-1Piper 100/200Checking Line and Grade

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

!

The grade readings must be taked from the same relative position in the
pipe. The illustration shows the readings being taken from the invert of
the pipe.

Determine the actual grade of the pipe

• Subtract distance “B” from distance “A” to determine the “rise” of the
pipe.

• Measure the horizontal distance “C” of the pipe.

• Divide the rise distance (A-B) by the horizontal distance (C), and then
multiply this value by 100 to determine the percent of grade.

Compare the measured grade to the grade dialed in the Piper

• Compare the measured grade to the grade shown in the display of the
Piper.

• If they are equal, the pipe is at the proper grade.

• If they are not equal, repeat the procedure to ensuure that a mistake was
not made. If they are still not equal, check the accuracy of the Piper and
the instrument being used.

Precautions:

To counteract hazards, it is essential for every user to respect the safety
precautions and control measures specified in the standard IEC 60825-1
(2001-08) resp. EN 60825-1:1994 + A11:1996 + A2:2001, within the hazard
distance *); pay particular attention to Section Three "User's Guide".

Following an interpretation of the main points in the relevant section of the
standard quoted.

Class 3R Laser Products used on construction sites and outdoors, for example
surveying, alignment, levelling:

a) Only qualified and trained persons should be assigned to install, adjust and

operate the laser equipment.

b) Areas in which these lasers are used should be posted with an appropriate

laser warning sign.

c) Precautions should be taken to ensure that persons do not look directly,

with or without an optical instrument, into the beam.

d) The laser beam should be terminated at the end of its useful beam path

and should in all cases be terminated if the hazardous beam path extends
beyond the limit (hazard distance *) of the area in which the presence and
activities of personnel are monitored for reasons of protection from laser
radiation.

10-15Piper 100/200Safety Directions

www.GlobalTestSupply.com

e) The laser beam path should be located well above or below eye level wher-

ever practicable.

f) When not in use the Laser Product should be stored in a location where

nauthorized personnel cannot gain access.

g) Precautions should be taken to ensure that the laser beam is not uninten-

tionally directed at mirror-like, specular surfaces for example mirrors,
metal surfaces or windows. But, more importantly, at flat or concave
mirror-like surfaces.

*) The hazard distance is the distance from the laser at which beam irradi-

ance or radiant exposure equals the maximum permissible value to which
personnel may be exposed without being exposed to a health risk.

For a pipe laser of laser class 3R this hazard distance is 662 m / 1252 ft. At
this distance, the laser beam rates as Class 1, that means direct intrabeam
viewing is not hazardous.
