CALCULATED INDUSTRIES Ultrasonic Tapeless Measure and Calculator

Introducing the Dimension Master Plus®

The Dimension Master Plus (v2.0) is a high-tech measuring tool that uses the latest in ultrasonic technology. This tapeless measure and calculator allows you to take quick and accurate measurements with the touch of a button. You can measure a single room in seconds or a whole building in minutes. The Dimension Master Plus features include:

• A special Aim Assist™ pointer lamp simplifying ultrasonic beam alignment,
• A built-in dimensional calculator that allows calculations and storage of measured values,
• Easy dimensional conversions using the “Convert” function key,

Background

How It Works

• Using a patented TriSensor Technology™, the Dimension Master Plus sends out an inaudible, narrow ultrasonic beam of sound that bounces off the “target” surface and returns to the unit as an echo. The Dimension Master Plus then determines how long the echo took to return and calculates a linear distance reading, while internally compensating for variables such as temperature. Unlike other ultrasonic measuring devices, the beam stays extremely narrow as it travels from the Dimension Master Plus. This exceptionally narrow beam allows you to measure through doorways, down corridors and in crowded rooms or offices for room-to-room measurements.
• To aid in accurate measuring, the Aim Assist™ pointer lamp enables you to pinpoint the center of the ultrasonic beam, thus avoiding interference from obstacles or clutter in your path.

Battery Information

When you first receive your Dimension Master Plus, you will need to remove the plastic tab sticking out of the battery compartment before you use it. 4 AAA Alkaline batteries are used to power the Dimension Master Plus. If a “lo batt” reading appears on the display, the batteries need to be replaced by removing the door on the back of the unit. The unit will continue to operate for approximately 2 hours after the low battery indication. For best results, use DURACELL® AAA (MN2400) batteries.

Feet/Inch or Metric Switch

• For your convenience, a switch on the left side of the unit allows you to set the measurement mode to either the English/Imperial Feet-Inch (F/I) system or to the Metric (Met) system.

Aim Assist™ Pointer Lamp

• The Aim Assist™ pointer lamp is designed for many years of service under normal operation.
• Should the bulb burn out, please contact the manufacturer for replacement details.

Display Accuracy

• The Dimension Master Plus has an eleven-digit display.
• This is made up of seven digits for the normal display and four digits for the fractional display.
• In a standard calculation, the calculation is carried out to a 10-digit internal accuracy, and then rounded to a 7-digit standard display using a 5/4 rounding.

Automatic Shutoff

• The Dimension Master Plus is designed to shut itself off after approximately 7 minutes of non-use.
• Any value shown on the display is cleared at this point.
• All values stored in the memory registers remain unchanged.

None/Error Messages

• If the Dimension Master Plus is unable to measure a distance, two beeps sound and either the word “none” or “Error” is displayed, depending on the measurement situation.
• The unit will also display “Error” if you make an incorrect entry, try to perform invalid dimensional calculations (i.e., adding areas and volumes together) or the resulting answer is beyond the range of the calculator.
• “Error” will also appear if you enter a mathematical impossibility, such as division by zero.
• There is no need to clear the “none” or “Error” message. The next valid measurement or keystroke automatically clears the display. The “none” or “Error” message will not clear previously stored values from memory.

New and Improved Features

The Dimension Master Plus (v2.0) gives you the following new features:

• Three new “Measuring Beam Modes”
  • Smart Mode
  • Narrow Mode
  • Wide Mode
• A new “Skip” mode which allows you to ignore an object in your measuring path
• A new, more powerful microprocessor.
• Expanded fractional setting accuracy.
• Expanded storage capacity.
• Easier to read display.

Measuring Beam Modes

One of the most important new features of the Dimension Master Plus (v2.0) is the addition of three different measuring beam modes:

• Normal Mode is the default setting and can be used for most measuring situations.
• Narrow Mode is used for higher accuracy within a confined space (narrow hallways, corridors, etc.) or when there is a need to eliminate interference from surrounding objects (such as bookshelves, lamps, etc.). Since this mode is essentially using a smaller beam area, this method requires careful alignment of the measuring beam.
• Wide Mode is used when walls are not parallel to one another or the alignment of the measuring beam is difficult. If there are several or large objects/obstructions in the measuring beam path, you may have difficulty obtaining accurate measurements using Wide Mode.
• [Rcl] [=] displays the current Beam Mode setting. [Convert] [=] is used the change the setting. The first press changes to the next Beam Mode setting and shows it to the left of the LCD display. Repeated presses of the [=] key toggle through the Beam Mode settings. Press any key, other than [=], to select a desired Beam Mode once that mode has been displayed on the LCD display.

Skip Measurement Mode

The “Skip Measurement” mode of the Dimension Maser Plus allows you to take accurate measurements in a cluttered room, without having to switch measuring modes. When the Dimension Master Plus takes a reading from an object in the way of your target, you can set the unit to ignore this measurement in future readings by pressing [Convert] then [5]. This ignored value will remain in memory until [On] is pressed twice, or the unit is powered down.

Greater Math Accuracy

• Equipped with a new, more powerful Integrated Circuit Chip, the Dimension Master Plus performs math calculations faster and with more accuracy.

Greater Fractional Accuracy

• With the addition of three new fraction denominator settings, greater fractional accuracy can be achieved. Use the following methods to display the fraction denominator setting:

Method 1

• Press [Rcl] [/] to display the current fraction denominator setting. Press [+] or [-] to scroll through the settings (1/2”, 1/4”, 1/8”, 1/16”, 1/32”, 1/64”).
• Once the desired setting is displayed, press any key, other than [+] or [–], to “set” your setting selection.

Method 2

• Use the keystrokes below to select and “set” the desired fraction denominator setting:

Note: 1/8” is the default setting. When a fraction denominator setting other than the default setting of 1/8” is being used, a star ( ) will appear on the  display when the unit is turned on.

Fractional Feet-Inch/Decimal Toggle

• Now “Fractional Feet-Inch” values can be converted to “Decimal” values and back by pressing [Convert] and repeatedly pressing the [Feet] or [Inch] key to toggle between formats.

Greater Storage Allocation

• With the addition of extra storage registers, you can now store [Length], [Width] and [Height] measurements. Once stored, these values can be easily recalled and used with other measurements when calculating area and volume.

Expanded Use of [LxW] and [LxWxH] Keys

• When area and volume are calculated, the results are displayed in the last used unit of measure. Repeated presses of the [LxW] or [LxWxH] keys recalculate the results for each available unit of measure.

Expanded Memory Functions

• Your Dimension Master Plus includes the following functions for greater flexibility during use:

Function Keystroke

• Add displayed value to Memory [M+]
• Display & clear value in Memory [Rcl] [Rcl]
• Clear value in Memory, not the value in display [Convert] [Rcl]
• Subtract displayed value from value in Memory [Convert] [-] [M+]
• Replace value in Memory with displayed value [Convert] [Rcl] [M+]

How to Use the Dimension Master Plus

• Taking Accurate Measurements Be sure to hold the Dimension Master Plus still and directly parallel to the target area while taking a measurement. The Dimension Master Plus may give an inaccurate reading or a none/error message if it is moved or held at an angle while you are attempting to take a measurement.
• Make sure that you hold the Dimension Master Plus in such a way that your fingers do not cover the three Ultrasonic Sensors on the front of the unit or the Thermistor (automatic temperature sensor) located on the bottom left hand side of the unit. The Dimension Master Plus must be able to accurately sense the ambient temperature of the surrounding environment in order to work properly.
• The Dimension Master Plus works best when aimed at smooth surfaces that easily reflect the ultrasonic measuring beam back to the unit. For example, when aiming the Dimension Master Plus at a window covered by a curtain, open the curtain to ensure an accurate measurement.

Taking a Linear Measurement

1. Place the back of the Dimension Master Plus on a flat surface parallel to the target area (e.g., hold the back of the unit against the wall across from the parallel wall you are targeting).

2. Press the “Measure” button (the blue button on top of the unit) down halfway to activate the Aim Assist™ pointer lamp.
   Note: The Aim Assist™ pointer lamp’s beam is visible for 35 to 40 ft. If you are measuring in a brightly lit area, the beam may not be visible. Even so, the narrow beam ensures an accurate measurement.

3. Press the “Measure” button down completely to take your measurement.

4. The word “Run” displays while the Dimension Master Plus is measuring. When the distance has been calculated, a single beep sounds and the measurement value appears on the display.

Note: If the Dimension Master Plus is unable to measure the distance, either the word “none” or “Error” (depending on the measurement situation) will appear on the display. Two audible beeps will then sound alerting you to a measurement problem.

Taking an Area Measurement

1. Measure the length of the room as described in steps 1-4 above.
2. When the measurement is displayed, press [Length] to enter the value.
3. Measure the width of the room.
4. When the measurement is displayed, press [Width] to enter the value.
5. Press [LxW] to display the area calculation.

Note: There is no need to clear the display after each measurement. The Dimension Master Plus automatically clears the display with each new measurement.

Volume Measurements
To take a volume measurement, follow steps 1-4 shown for area measurement. Take a third measurement and press [Height]. Press [LxWxH] to display the calculated volume. Your measurement is now displayed in cubic dimensions.

Note: Area and volume measurements can also be calculated by entering values manually into [Length], [Width] and [Height].

Large Room Measurements
If you want to measure a room beyond the 60-foot range, take two linear measurements. Stand in the center of the room and take one measurement in one direction. Turn around and take a second measurement in the opposite direction. Follow the directions below to add both measurements to the cumulative memory:

1. Pick a point in the center of the room. In one direction, take the first measurement towards the wall. When the measurement is displayed, press [M+].
2. In the opposite direction, take the second measurement to the opposite wall. When the measurement is displayed, press [M+].
3. Press [Rcl] [M+] to display the cumulative total that has been stored in Memory.

Entering Dimensioned Values
When entering dimensioned values, enter the largest dimension first; feet before inches, inches before fractions. Enter fractions by first entering the numerator (value above the line), then press the [/] key, then the denominator (value below the line).

Note: The first valued dimension entered in a problem determines the format of the result.

For example

• 63 yards + 59 inches = 64.63889 yards
• 63 meters + 59 inches = 64.499 meters

Dimension Examples
Enter the following dimensions (clear after each entry)

Note: Yards and meters may only be entered as whole (5 yards) or decimal (5.5 meters) values, not in combination with feet-inchfractions (5 feet 10-7/16 inches).

Enter the following square dimensions

Environmental Conditions

Temperature — The Dimension Master Plus uses automatic temperature compensation for ensuring the consistency of measurements in the temperature range of 32ºF to 100ºF (0ºC to 38ºC). The response rate of this circuitry enables you to move between warm and cold areas and measure with reasonable accuracy. However, we recommend that you do not leave your Dimension Master Plus in very cold or very hot conditions (e.g., sunlight in a car), as the unit will then require more time to adjust to ambient temperature.
As long as the internal temperature is approximately equal to the ambient temperature, accuracy is unaffected. It is best to wait a few moments for the unit’s internal temperature to stabilize to the ambient temperature. You may compensate for this by adding 1% of the measured distance for each 10ºF (5.5ºC) that the internal temperature is below the actual ambient temperature or subtracting 1% of the measured distance for each 10ºF (5.5ºC) that the internal temperature is above the actual ambient temperature.

Humidity and Altitude — Humidity and altitude can affect the maximum measurement distance and beam angle of all ultrasonic distance-measuring tools. As the humidity increases or the altitude decreases, the maximum measurement distance and beam angle is reduced. As humidity decreases or the altitude increases, the maximum range and beam angle is increased. Therefore on a day with a very low humidity you are more likely to detect objects over a wider field of view and at a greater distance.
Outdoor Measurements — The Dimension Master Plus is primarily designed for indoor use. It may also be used outdoors, provided there is only light wind. A strong wind will tend to affect the maximum measurement range.
Moisture — Your Dimension Master Plus is a high precision measuring device that is open to the atmosphere. For this reason, it should not be used in conditions (i.e., rain, mist, etc.) where moisture can get within the unit.
