Introduction
Congratulations on your purchase of a Stanley Tools Contractor Grade
COMPULEVELTM.With it, you’ve entered into an exciting new world of
elevation measurement and levelling.
• COMPULEVELTM is the first instrument of its kind to let you work alone
and even around corners with better than 1/-8” precision to cover up
to 40’ vertically over a 200’ circle on a single set up.
• COMPULEVELTM directly displays vertical measurements in large, easy
to read digits (unlike conventional builders and laser levels). You can
select any of six scales in which to work for extra convenience.
Owning a COMPULEVELTM is like owning six 40’ rods and an imaginary
20’ tripod, all in one convenient package.
In addition you can:
• Use the CARRY function, to take elevation measurements across
unlimited ranges with multiple set ups, and without paper, pencil,
tedious calculations and endless errors.
• Attach a Serial Link to COMPULEVEL’s built in Serial Port and make
COMPULEVELTM apowerful data gathering instrument capable of
downloading stored measurements to a Personal Computer for
analysis and tabulation or plots of profiles, sections and topographical
maps.
• Use any of COMPULEVEL’s 15 powerful built-in functions to master
tough elevation measuring and levelling jobs from site planning and
excavation throughout construction to final grading and landscaping.
• Never again worry about calibration because the rugged, water
resistant COMPULEVELTM is easily checked and quickly field
calibrated.
Carefully review this User’s Guide and with a little practice you’ll soon cut
time, cost and frustration from your site measurement tasks.

COMPULEVELTM Basics continued
To use COMPULEVELTM:
1) Secure the base unit on its back at any convenient location and pull
from the reel ample cord to cover the area to be measured. The cord
will communicate elevation information from the base unit to the
measurement module.
2) If desired, attach the unipod to the measurement module to avoid
bending to measure. The unipod is not required for operation.
3) Turn on the unit and zero with the ZERO button at any site reference or
benchmark within COMPULEVEL’s 200’ horizontal, and + 20’ vertical
range. Although it is not necessary for the base unit to be level, it must
be secure.
Note:If the base unit moves, you must re-zero the measurement module
at the bench mark before continuing.

The Measurement Module
The hand-held measurement module, linked to the base unit by its polymer
cord, is the COMPULEVELTM component you use to take the actual
elevation measurements.
When taking measurements, the bottom and back of the measurement
module are the only sides that may be used interchangeably for
measurements. Hold the module level at the point where you want to
measure. Measure near the centre of either the back or the bottom.
Other sides may be used throughout any series of measurements, but
measure only with the surface you used to zero COMPULEVELTM –Do not
change one surface to another for measuring without re-zeroing the unit.
Never invert the measurement module without compensation (see
illustration) unless it was inverted when zeroed. It will not show the
correct elevation.
Example: To measure the distance between the floor and ceiling in the
illustration on the opposite page: 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. To get the correct measurement, you then
manually add the height or thickness of the measurement module to the
display reading, or do so automatically using the ADDER function
described later.

Keypad
Use the keypad to control the COMPULEVELTM.The most frequently used
functions – called labelled functions – are printed on the eight keys below
the display on the measurement module.
COMPULEVEL’s more advanced or less frequently used functions – called
hidden functions – may be accessed by logical combinations of two or
more of the same keys. All keys except the HOLD and ON/OFF keys must
be pressed and held for two seconds to activate. This minimises
accidental operation of the functions.
All function keys also emit distinctive audible signals (clicks and beeps)
and show visual indicators on the display to further ease use. With use
these are quickly recognisable.
Examples: When a measurement is nearly stable enough to read,
COMPULEVELTM emits two short ‘read ready’ beeps.
When storing a reading, COMPULEVELTM emits short, regular beeps and
the display flashes until the reading is stable enough to store. The unit
then emits a single long tone.
Note:All most recent settings and stored measurements are retained
indefinitely once power is shut off and even without a battery installed.

Quick Start
Although most COMPULEVELTMusers will use only those functions
routinely necessary in their work, we recommend that you try all
COMPULEVELTM functions at least once to become familiar with its
capabilities. The use of all COMPULEVELTM functions is detailed in
this guide.
These quick start pages, however, show the operation of a few basic
functions that most users will employ and they will help you gain
confidence in working with all of COMPULEVEL’s functions.
To take basic elevation measurements with COMPULEVELTM:
1) 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.
2) Pull from the reel ample cord to cover the area to be measured.
Momentarily press the ON/OFF key to turn the unit on. The ON/OFF key
will click when pressed and the unit will emit a double a beep.
3) Place the measurement module on a nearby horizontal surface. When
the reading has settled, it will emit two quick beeps. Then, press and
hold the ZERO key for two seconds. Keep the measurement module
steady until the numeral zero appears on the display. The unit is now
zeroed on this reference point.
4) Move the measurement module to a different elevation (from a table to
the floor, for example). It will display the difference in elevation from
the first location to the second. Move it to a thirdlocation and it will
display the difference in elevation from the first location to the third
(current) location.
5) Momentarily press the ON/OFF key to shut offthe unit. Reel in the
cord, dock the measurement module in its storage compartment and
lock the door.
WARNING:READ AND UNDERSTAND THIS ENTIRE USER’S GUIDE

Mechanics of Use
Labelled Functions
The following section describes how to operate COMPULEVEL’s labelled
functions. Glance through all the functions and the example illustrations
then try each function on your COMPULEVELTM.
ON/OFF
Momentarily press the ON/OFF key to turn COMPULEVELTM on or off. If no
key is pressed, or the measurement module is not moved in four minutes,
the unit powers down automatically. The unit emits two long warning
beeps after three minutes of no movement or keypad activity to warnof
shut-off activity.
HOLD
The HOLD function is used to make and retain a measurement from any
location where the display is hard to see, such as overhead, in a deep
trench, or anytime you want to hold a measurement on the display while
moving the measurement module. The HOLD function is toggled on/off by
momentarily pressing the HOLD key.

Scale & Resolution
SCALE
You can choose any of six scales measuring elevation with
COMPULEVELTM:1) fractional inches, 2) decimal inches, 3) feet,
4) feet and inches, 5) centimetres, 6) meters.
To choose a measurement scale:
Press and hold the SCALE key for two seconds. Continue pressing the
SCALE key to sequence through all the scales. Release on the desired
scale. The current scale is indicated on the right side of the display
window.
RES
You can choose one of three level’s of resolution or measurement
precision in which to work with COMPULEVELTM.Res 1, offers the highest
precision but requires longer for a reading to stabilise. Res 2, provides
intermediate precision and takes less time to obtain a stable reading.
Res 5, is best for rough measurements and provides the fastest readings.
To choose the preferred resolution:
Press and hold the RES key for two seconds to enter and continue
pressing to select the desired measurement resolution. The current
resolution level (ie. 1/8”, 1/4" or 1/2" when using inch scales) is shown

Calibration
CAL
COMPULEVELTM will need to be calibrated when there has been a
temperature change of 36°F (20°C) or greater since the last calibration.
COMPULEVELTM signals the user that it requires calibration by flashing the
word ‘CAL’ in the measurement module display window. Calibration is
done by the user, in the field, in minutes, as described below.
To calibrate COMPULEVELTM:
1) Place the base unit on its back on a level, flat surface and turn it on.
2) Place the measurement module on its bottom or back side next to the
base unit. Press and hold the CAL key for two seconds.
3) When the display flashes [0] press the CAL key momentarily.
4) When [48] flashes on the display, raise the measurement module to 48”
above the base unit and momentarily press the CAL key again while
holding the measurement module steady. Note: The fully extended,
calibrated unipod, a plywood sheet, or a tape rule mark on a wall can
be used as a calibration standard.
5) When the display stops flashing and shows “48”, the unit is calibrated.
Notes:You may exit without calibrating at any time during the procedure
by pressing and holding the CAL key for two seconds.
At any time, you may quickly check calibration by first zeroing beside the
base unit and then checking for a 48” reading at an appropriate location
above the zero benchmark. CAL may flash on the display indicating that
re-calibration is required.
CALIBRATION IS CRITICAL FOR ACCURATE VERTICAL MEASUREMENTS.
It is not required for levelling operations.
