consists of a Base Unit (BU) and hand-held Measurement Mod-
ule (MM) joined by a rugged wireless Cord that communicates elevation data
from the BU to the MM. Stakes secure the Base Unit on unstable terrain. A
Unipod eliminates constant bending for multiple readings and doubles as a
vertical calibration standard when fully extended. All components are stored
in the Base Unit when not in use. To use
1) Secure the Base Unit on its back at any convenient location and pull
enough Cord from the reel to cover the area to be measured. If desired,
attach the Unipod to the Measure Module. Although it is not necessary
for the Base Unit to be level, it must be secure.
2) Momentarily press the ON/OFF key to turn on the
3) Press the ZERO key for 2 seconds to set a level zero plane at any refer-
ence or benchmark within
’s 200’ (60m) horizontal, and +/- 20’
(6m) vertical range.
Note: If the Base Unit moves, you must re-zero the Measurement Module at
the benchmark before continuing.

To remove the boot:
1. Place against chest
2. Pull back 1” with 4 fingernails each side.
3. Grip Measurement Module and Boot
and pull Boot off.

Use the Measurement Module to level and take readings. The bottom and
back of the Module are the only sides that may be used interchangeably for
measurements. You may use other sides only if you first zero on that side.
Hold the Module level and measure near the center of the side in use. Do not
zero the Module and then invert it without correcting the reading as shown in
the illustration on the next page.
Example: To measure the distance between the floor and ceiling: First, zero
the Measurement Module on its back or bottom on the floor. Then place its
top, bottom, or back against the ceiling to take a reading. Finally, add the
appropriate correction factor shown in the illustration.

Use the keypad on the Measurement Module to control the
take readings. The most frequently used functions, called labeled functions,
are printed on the eight keys below the display.
’s more advanced or less frequently used functions, called hidden
functions, may be accessed by logical combinations of two or more keys. All
keys except the HOLD and ON/OFF keys must be pressed and held for two
seconds to activate. This minimizes accidental operation of the functions.
Distinctive audible and display indicators ease use – you will soon learn to
recognize them. For example, when a measurement is nearly stable enough
to read, you will hear two short ‘read ready’ beeps. When storing a reading,
emits short, regular beeps while the display flashes. When the
reading is stable enough to store, the unit then emits a single long tone.
Note: All stored measurements and settings are retained indefinitely once
power is shut off and even without a battery installed.

their work. We suggest that you try all
functions at least once
to become familiar with its capabilities. This Quick Start will help you gain
confidence by using a few frequently used functions:
Raise the lower door of the Base Unit, remove the Measurement Module
and lay the Base Unit on its back on the floor or ground. The Base Unit
should be secure but need not be level.
Pull enough Cord from the reel to cover the area to be measured and
momentarily press the ON/OFF key to turn the unit on.
Place the Measurement Module on a nearby surface and press the ZERO
key for 2 seconds and hold steady until zeroed. You have now created an
imaginary infinite size level reference plane.

Unlike rotary lasers and optical levels, the
is not tilt sensitive,
its level plane does not develop tilt error and it does not amplify error with
distance or require factory calibration. The CAL function lets you calibrate
vertical measurement accuracy much like calibrating the vertical sight rod
of a rotary laser. Calibration may be needed for accurate vertical measure-
ments but is not required for leveling operations.
Always check calibration before doing accurate vertical measurements,
particularly if the temperature has changed 36°F (20°C) or more since the
last calibration causing CAL to flash on the display or if you have never
calibrated a new or newly serviced
. You can easily check cali-
bration in two steps: 1) Zero the Measurement Module on bottom or back
on a flat surface beside the Base Unit. 2) Raise the Measurement Module
4’ (121.9 cm) above the zero point (still on bottom or back) to be sure the
display closely matches the height raised. The fully extended and calibrated
Unipod, a sheet of plywood or a tape rule can be used as a calibration
standard. If calibration is necessary then follow the easy 3 steps in the il-
lustration. You can exit from calibration at any time by pressing the CAL key
for two seconds.

The RECord function eliminates extensive tabulation and computation re-
quired to average large numbers of readings. Now you can easily estimate
the slurry necessary to level an uneven concrete surface, the fill needed
below concrete or predict the graded level of a hilly lot (see illustrations).
You can also estimate the volume of a pile of dirt or the volume to fill a hole
by first finding the difference between the average of readings every pace
around the edge of the pile or hole and the average of readings at every
pace criss-crossing the pile or hole. Volume = (difference of the two aver-
ages) X (estimated cross-sectional area of the pile or hole).
To enter the record function, press REC 2 seconds causing REC to appear
on the display. Momentarily press REC to display current reading, AVG (av-
erage), MIN (minimum) or MAX (maximum). Press HOLD momentarily to
include each of an unlimited number of readings in the computations.
Press REC 2 seconds to exit the Record function. Previously computed data
will be replaced with new data if you press the HOLD button after re-entry.

The High Precision function lets you measure with an unprecedented paper
thin 0.005” (0.1mm) internal precision over a vertical range of 4’ (1.2m).
With this revolutionary capability you can detect minute surface errors, set
precise pool negative edges, precisely fixture shop fabrications or set plant
equipment and do real time beam deflection measurements. The possibili-
ties are endless.
To enter or exit, momentarily press ON/OFF while pressing the RES key.
You must re-zero when changing in or out of High Precision. When in High
Precision, HP will appear with readings in decimal inches, feet and centime-
ters. For a lower precision, press the RES key for at least 2 seconds and
release at the desired precision. Vertical calibration (CAL) is still done at 4’
(121.9cm). With the highly precise HP measurements it is particularly impor-
tant to comply with the How to Measure Accurately Guidelines on Page 32.

CAL Flashes if unit needs to be re-calibrated due to a 36F (20C) tempera-
ture change since last calibration. CAL is on constantly when unit is
outside of the -22°F to +158°F (-30C to +70C) operating temperature
range. CAUTION: Vertical measurements may be in error.

due to a temperature change of 18F (10C) since the last zero.
8888 Alternates with displayed elevation when the Measurement Module
is more than 20’ (6m) above or below the Base Unit. CAUTION:
Overrange measurements may be in error. If 8888 flashes well
within range, check troubleshooting chart; check for Cord damage
or leakage and if necessary, return for service.
BAT Flashes when only a few hours of battery life remain. A fresh 9V
alkaline battery can allow up to 60 hours of active use.
CORD Flashes to indicate need for routine factory Cord recharge required
about every 3 years or possible Cord damage. CAUTION: Measure-
ments may be in error.
*See page 6 for illustration of alarm indicators.
1) Secure the Base Unit after removing the Measurement Module.
2) Extend the Unipod from the top down and retract from the bottom up (see
page 14). Always gently tighten bushings (avoid over-tightening).
3) Hold the Measurement Module in the handgrip areas to the right and be-
neath the keypad. For single handed operation, use the thumb to press
the most frequently used buttons: ON/OFF, HOLD and ZERO. The left
hand can manipulate the Cord. Release or hold steady while reading (see
4) In muddy conditions use a rag to wipe down the Cord before reeling in.
This can also remove Cord twists.
5) Place Module on ground beside Base Unit then pick up Base Unit and reel
Cord through Cord entry area by holding the Base Unit handle with Base
Unit tilted backward at about 45° (for example, resting against thigh). This
will ease reeling, reduce wear and keep docking area clean (see page 8).
6) Use a coin, screwdriver or thumbnail to loosen battery door screw to re-
place 9V alkaline battery. Lift the terminal end of battery with thumbnail
or simply thump Measurement Module against your hand and catch the
battery. Note: The protective Boot is more easily removed when warmed.

HOW TO MEASURE ACCURATELY ▪ 32
isothermal readings are typically precise to within 0.2% of mea-
surements 10’ (6m) or less and 0.35% of measurements beyond 10’ (6m).
It can typically level to within 0.1” (2mm) or 0.01” (0.2mm) in High Precision
over a single set-up.
1) For critical levelling frequently re-check or re-zero at the benchmark (CAL
is not necessary for leveling). When possible minimize height differences
between Cord, Base Unit and Measurement Module.
2) For critical elevation measurements, frequently re-check calibration and
benchmark zero. Whenever possible avoid temperature differences be-
tween the Cord and Measurement Module (eg. sun vs. shade).
3) When moving the
from one temperature to a much different
temperature, such as from indoors to outdoors on a cold day, pull out as
much Cord as needed and allow 10-15 minutes for
to the change.
4) Avoid violent tugging, whipping or stomping on the cord without re-check
or re-zero at the benchmark.
5) Promptly zero or calibrate
when its display flashes –0– or CAL.
6) Always secure the Base Unit to prevent movement during measurements
– it does not need to be level.
7) Avoid using
beyond the specified ranges of elevation or tem-
perature. The display will flash 8888 when beyond the +/-20’ (6m) vertical
range and the CAL will be on steady for temperatures below -22°F (-30C)
or above +158°F (+70C).
8) Occasionally check the 4’ (121.9cm) length of the fully extended Unipod
for changes in length caused by wear. Adjust its length if necessary.
9) As with conventional instruments, additional errors may be caused dur-
ing use outdoors on sunny or windy days. In such conditions pull out only
as much Cord as is needed and avoid unnecessary loops over objects.
Measurements are less affected by sun/shade in early morning, late af-
ternoon, when overcast, in full shade or indoors. If a measurement varies
when breezy, take the average reading.
33 ▪ HOW TO MEASURE ACCURATELY
is rugged, durable and designed to provide years of reliable
performance when properly used. Here are some guidelines:
1) Avoid excessive strain on the Measurement Module by guiding the Cord
with the left hand during use (see page 8).
2) Whenever possible use the protective boot on the Measurement Module.
Avoid dropping the Measurement Module and never use as a hammer.
3) Do not immerse the Measurement Module in water or any other liquid or
gas and avoid contact with solvents.
wear by wiping with a damp cloth (avoid scratching
display window) or rinsing lightly to remove mud and dirt from the Base
Unit, Cord and Measurement Module. In extreme cases the single screw
at the back of the reel can be removed to release the reel from the hous-
ing for a thorough hosing.
5) Keep the Cord, Measurement Module or Base Unit out of the path of
vehicle traffic and out of contact with hot objects such as smoldering
cigarette butts, fresh asphalt or welding.
