INTRODUCTION
The Ultra Scale Master
has been specifically
designed to simplify
take-offs for all fields
of construction. Use it
for estimating project
materials and costs, for
measuring, storing and
calculating perimeters,
areas, and volumes from
architectural plans and
other types of scaled
drawings. Also, use the
Ultra Scale Master to
calculate the area of
irregular shapes.

GETTING STARTED
Once assembly and setup are complete, proceed with the following steps in
order to begin measuring.
1. When placing the bars and securing the drawing, make sure that the
bars are at least 1" from the outermost measurements.
2. It is essential that the bars remain fixed relative to the drawing’s
position. Scribe a line to mark the initial location of the bars as a
reference point should the bars shift.
3. The Puck should maintain a 45° angle within the bars while measuring.
4. Ensure that the measuring surface is flat and smooth. Make sure there
are no folds, tears, or raised areas of the plans.
5. Make sure there are no objects between the Puck and the bars. This
includes hands, arms, pencils or pens, cups, scale rulers, etc.
6. Make sure that no air current is blowing directly into the measuring
area. Air blowing into the measuring path can result in no
measurement reading.
7. To get accurate measurements, make sure that the Puck and the bars are
close to the ambient temperature of the work environment.

[END]
Ends polyline measurement,
displaying the total perimeter.
[CLOSE —]
Completes the polygon and
displays the calculated area.
Results are identified as negative
values. When measuring a
polygon, this key connects the last
measured point to the start point.
KEY DEFINITIONS
MEASURING KEYS
The keys shown are used
for taking measurements on
the blueprint and operating
the display.

USER’SGUIDE — 11
[ON/CLEAR]
Turns the unit ON and clears
the display. Holding down the
[ON/CLEAR] key for 1.5 seconds
also powers the unit off.
[CLOSE +]
Completes the polygon
and displays the calculated
area. Results are identified
as positive values. When
measuring a polygon, this key
connects the last measured
point to the start point.
[MEASURE]
Takes a measurement
between points.
Important Notes
regarding the
[ON/CLEAR] key:
If [ON/CLEAR] is pressed
during measurement,
the last measured point
is undone and the
previous measurement is
displayed. A second press
of [ON/CLEAR] ends the
measurement (as if the
[END] key was pressed)
and clears the main display.
Additionally, if an error
message is displayed
during a measurement,
pressing [ON/CLEAR]
clears the error message
and displays the previous
measurement.

[UNDO]
Undoes the previous measurement.
Allows you to undo the last ten
measurements (if applicable) while in
measure mode. If a measurement has
been closed or ended, it will undo the
close or end action and the previous
nine measurements upon repeated
presses of [UNDO].
[SET]
Used in conjunction with the [SCALE]
key to set a custom scale (see Custom
Scales section). Also used to access
secondary functions (e.g., M-, MC).
[AREA]
Displays the calculated area of the
measured points.
5
UPARROW
Used to change the units of measurement
and increase the selected digit while setting
a custom scale (See Custom Scales section).

the accumulative memory (except
during a measurement).
[MR] (Memory Recall)
First press displays the accumulative
memory value; second consecutive press
displays memory count; third consecutive
press displays the memory average.
Repeated presses cycle back through the
list of values.
4RIGHT ARROW
Used to move through the digits
while setting a custom scale (see Custom
Scales setting).
[SET] [MR] (Memory Clear)
Clears the accumulative memory.
[PERIM]
Displays the calculated perimeter
(accumulated length) of the
measured points.
6DOWN ARROW
Used to change the units of measurement
and decrease the selected digit while setting
a custom scale (see Custom Scales setting). USER’SGUIDE — 13

[MODE]
Used to select from the list of
available modes (see Built-In
Scales section).
[SET] [MODE]
Used to move back through the
list of available modes.
[SCALE]
Used to select from the list of
available scales within each
mode (see Built-in Scales section).
[SET] [SCALE]
Used to move back through the
list of available scales.
[RESET]
Clears all values and resets all
settings including preferences
to their factory defaults. (Use the
end of a paperclip or something of
similar size to press.)
SETUP KEYS
The buttons shown below
are accessed by sliding the
bottom cover down until
they are revealed.

BUILT-IN SCALES
The following modes and scales
are available for selection using
the [MODE] and [SCALE] keys,
depending on whether the puck
is set to Imperial or Metric mode
using the [IMP/MET] switch
located on the back of the puck.
While in Imperial Mode, only the
Imperial Modes and Scales are
displayed. While in Metric Mode,
only Metric Modes and Scales are
displayed. However, all Imperial
and Metric units of measurement
are available within both modes.
When switching back and forth
between Imperial and Metric
modes, your settings within
each mode are held, including
Preference. The values stored in
[M+] are cleared when switching
between Imperial and
Metric modes.
Note: While in Metric Mode, MET
will appear in the scale area of
the display to indicate that it is in
Metric Mode.
