Key Layout & Definitions - Both Models The DigiRoller/DigiRoller Plus is unique to measuring wheels because it has keys that allow you to store and manipulate the distances measured. The following is a list of keys that you may use as you operate the unit: (see page 10 for a list of LCD annunciators) Power On/Off Key — Turns the unit on or off. Length Key — Enters and stores rolled length value. Width Key — Enters and stores rolled width value.
Area Key — Calculates and displays rolled area. Units of Measurement Key — Selects desired unit format: Feet-Inches, Decimal Feet, Decimal Inches, Yards, Meters, and Acres (display only). Each press of this key will convert the displayed measurement to another unit format. Delete/All Clear Key — Deletes, or erases, the values stored in the next key pressed (e.g., [DEL] [L] deletes the current measurement stored as length, [DEL] [W] deletes the current measurement stored as width, etc).
Memory Subtract Key — Subtracts the displayed value from permanent memory. Set Key — Used to access special functions. Add Wheel Radius Key — Adds the radius measurement of the wheel to the total linear measurement, to allow for true wall-to-wall distance. Reset/Clear Display Key — Clears the display to 0. Does not clear stored values. Start/Stop Key — This key switches the unit between start and stop modes. You will press this key to begin measuring.
DigiRoller Plus model (only) The DigiRoller Plus model has an additional row of keys. Multiple Area Storage Key — For each of the 9 area number registers, you can store length, width, height, area, volume, and wall area. Height — Stores a fixed height distance or a rolled height for calculating cubic volumes and wall areas. Volume — Calculates volume measurements from entered or stored length, width, and height values.
matically count each time it reaches the distance you have set (for example, it will count the number of times you roll 5 feet), and show the number of times it has measured this distance on the upper left of the display. Light Key — Turns the display back-light on or off. Using the Display Clearing the Display To clear the display, press the [RESET] key. Changing the Display Contrast Level You can control the brightness of the display by adjusting the contrast level setting.

You will see the display registering your measurements.
3) When you are finished measuring, press the [Start/Stop] key again. 4) To store the measurement, press the appropriate key (ex. [L] for length, [W] for width). If you do not store the measurement, you can then press the [Start/Stop] key again to continue measuring. 5) If you have stored the measurement, press the [Start/Stop] key to begin a new measurement. If you didn’t store the measurement, press the [RESET] key to clear the display then begin rolling.
Storing and Recalling Values The DigiRoller/DigiRoller Plus has several keys that can be used to store and recall values: The DigiRoller Plus can also store and recall values in the [H], [LxWxH], [AutoCount], and [Area#] keys. To recall any of the values above, press the [Rcl] key and then press the key that has the value you want to display. For example, to recall the length that was rolled, press [Rcl] [L].
Deleting Stored Measurements To permanently delete a stored value, press the delete key [DEL] and then the key that has the value you want to delete. Be careful when pressing the [DEL] key, as it will permanently erase the stored value of the next key pressed. If you accidentally press the [DEL] key, press [RESET] to prevent any stored value from being erased.
Taking Wall-to-Wall Measurements Unlike other measuring wheels, the DigiRoller/DigiRoller Plus has a built-in function which enables you to measure true wall-to-wall distances (taking into account the wheel’s radius when measuring up to a wall). The wheel radius key [+D] will add the radius of the wheel to the measurement. To measure a room accurately, press the wheel radius key whenever your measurements begin or end against one wall.
Taking Area Measurements Your DigiRoller/DigiRoller Plus automatically calculates areas once you’ve rolled a length and width. Remember, press [RESET] to begin each new measurement. 1) Roll the first distance. Press the length key [L] and your rolled distance will be automatically stored as the length. 2) Press [RESET]. Roll the second distance and press the width key [W]. 3) Press [RESET]. Press the [L x W] key to calculate the area.
Calculating Complex Areas You can calculate complex areas using the DigiRoller/ DigiRoller Plus easily. Using the memory keys [M+], [M-], you can add and subtract measurements from your total area. See the diagram below. . To find the total area, you will need to divide the area to be measured into sections (see diagram below) and find the area for each section. Then you can subtract the empty area from the total area.
Step: Key: Roll & store width [W] Find area Store area in memory [L x W] [M+] Step 2 - Find area to be subtracted Step: Key: Roll & store length of empty space [L] Roll & store width [W] Find area [L x W] Subtract from total in memory [M-] Calculate actual area [Rcl] [M+] 20 – DigiRoller/DigiRoller Plus ™
DIGIROLLER PLUS FEATURES Lighting the Display Background The DigiRoller Plus has a built-in back-light to light up the display so that you can read your measurements better in poorly-lit environments. 1) Press the [Light] key to light up the display. 2) Press the key again to turn the light off. 3) If you forget to turn the light off, it will shut itself off automatically after 8-12 minutes. Using the light consumes battery power more rapidly; use it only when necessary and turn it off when you are done.
Taking Volume Measurements The DigiRoller Plus is programmed to quickly and easily calculate volumes if you’ve rolled in a height or if you’ve set a fixed height. You can roll or set a height for each of the nine Area Number storage registers. Once you roll or set a height, it is used for all subsequent volume calculations unless you change it. Remember to press [RESET] to begin each new measurement.
Calculating Volume Using a Fixed Height To set or program a fixed height, for example, eight feet-seven inches, do the following: Step: Key: Enter program mode [Set] [H] The Feet-Inch annunciator will start flashing. Press [M+] if you want to change the units of measurement. The display will scroll through the various units of measurement. Press [Set] to select the measurement unit and begin storing. The first zero (0) will start flashing.
Now you can find the volume using the fixed height you’ve just set. Remember to press [RESET] to begin each new measurement.
Storing Multiple Measurements Your DigiRoller Plus has a unique [Area#] key used for storing and recalling multiple measurements. You can store length, width, height, area, and volume for each of the 9 [Area #] registers. You can recall these measurements later, even if you turn off the DigiRoller (for example, to review your measurements back at the office). When you recall your measurements, you can also view totals for each (L, W, H, LxW, LxWxH, Wall Area).
Remember to press [RESET] to begin each new measurement.
Continue the above steps for each area you wish to calculate and store, up to 9 areas. If you try to store a tenth value, the word “FULL” will display. Press [RESET] to clear this error message. If you want to add this last value, you must then delete and/or edit the values stored in the Area Number registers. See the “Editing Stored Measurements” section for information on editing values in the Area Number registers. Recalling Stored Measurements To review your stored areas, press [Rcl] [Area#].
Recall Area #2 [Area#] Recall length [L] Recall width [W] Recall area [L X W] Recall total area [Area#] Continue until you have reviewed all your stored measurements. To exit the Area Number review mode, press [RESET].
Editing Stored Measurements Duplicating values in an Area Number register: Step Key Find Area Number Register with the value you want to duplicate [Area#] Find the value you want to duplicate [L] OR [W] OR [H] Store measurement in permanent memory [M+] Find Area Number with the value you want to replace [Area#] Recall replacement value [Rcl] [M+] Replace old value with duplicated value [Set] [L] OR [Set] [W] OR [Set] [H] To replace a value in an Area Number register: Step Key Roll measuremen
Step Key Find the value you want to replace [L] OR [W] OR [H] Recall replacement value [Rcl] [M+] Replace old value with new value [Set] [L] OR [Set] [W] OR [Set] [H] Deleting a value in an Area Number register: Step Key Find Area Number Register with value you want to delete [Area#] Delete value [DEL] [L] OR [DEL] [W] OR [DEL] [H] OR [DEL] [LxW] OR [DEL] [LxWxH] Note that deleting [LxW] and/or [LxWxH] also deletes the individual measurements contained (length, width, height).
Deleting All Area# Measurements Use the following special three key sequence to clear all measurement values previously stored in the [Area#] key: press [Set] [DEL] [Area#]. CAUTION: ALL stored values in [AREA#] will be erased at once.
Taking Wall Area Measurements The DigiRoller Plus can calculate the total wall surface area of a room. Wall area is defined as: ([Length x 2] x Height) + ([Width x 2] x Height) You will only need to roll a length and width, and roll or set a height. Then you can calculate the total wall surface area of that room. See the “Taking Volume Measurements” section for information on rolling or setting a fixed height.
Remember to press [RESET] to begin each new measurement.
Using Auto-Count/Fixed Distance Mode The DigiRoller Plus has an Auto-Count mode that allows you to count how many times you’ve rolled a certain distance (that you’ve set). If the bell is on, you will hear a short beep each time you roll that distance and the counter in the upper left of the display will increase by one. For example, you want to count the number of times that you roll 6 feet 8 inches.
Enter 8 inches [M+] (press 8 times) Store inch measurement [Set] Clear the display [RESET] Begin rolling. The unit will automatically count the number of times you roll 6 feet 8 inches and beep each time. Delete All Stored Values To clear all registers and stored values, press [Set] [DEL] [DEL].
APPENDIX Changing Batteries The DigiRoller/DigiRoller Plus is powered by 4 AAAbatteries. For best results, use DURACELL® (MN-2400) batteries. The batteries normally provide approximately 400 hours of use. You should replace the batteries when: ■ ■ ■ the display becomes weak or erratic the words “Lo Batt” show on the display the display light is dim 1) Turn the unit off and position the unit so that the handle faces you.
2) Remove all four batteries and insert four new ones. Insert two of the batteries on the left side with the positive ends facing outward; insert the other two batteries on the right side with the negative ends facing outward (see diagram). 3) Replace the battery compartment cover. Tighten the screw on the cover. CAUTION: Batteries contain hazardous chemicals. Please dispose of used batteries properly.
