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.

When you press this key, the DigiRoller will add distance to
the measurement. Depending on your selected wheel size and
measurement units, the first and second presses of this key
may not appear to be adding equal distances. However, this is
a display value only; internal calculations will be accurate.

5. If you change the wheel, be sure to re-calibrate the unit so
that it will measure correctly.

6. As with all measuring wheels, measurements will vary
when rolling “against the grain” of the carpet. Be sure to
take this difference into account when measuring indoors.

Common Questions & Answers

Q: My DigiRoller/DigiRoller Plus won’t register measurements when

I roll. What’s wrong?

A: Make sure you press the [Start/Stop] key to start your measuring

(display will no longer show the stop symbol when unit is in start
or measuring mode).

Q: My display shows the words “Lo Batt.” What does this mean?

A: When you see the Low Battery Indicator “Lo Batt,” replace all

four of the AAA batteries. You may purchase replacement batter­ies at any store.

Q: My DigiRoller/DigiRoller Plus display is dim and hard to read.

How can I make the display easier to read?

A: You may adjust the LCD contrast control for easier viewing (see

the section “Changing the Display Contrast Level” on page 8 for
instructions on changing the contrast level).

Q: My measurements are coming up (long/short) when I roll on car-

pet. What’s wrong?

A: As with all measuring wheels, measurements will vary when

rolling “against the grain” of carpet. Be sure to take this difference
into account when measuring indoors.

Q: I’ve taken several measurements for the same thing but the mea-

surements are different. Is something wrong with the DigiRoller?

A: When you are measuring a distance, you need to ensure that you

start and stop your measurement while holding the DigiRoller at
the same angle (preferably upright or vertical). If you do not, your
measurement may be inaccurate. When you move the unit from
an angled to a vertical position or vice versa, the unit will add or
subtract by as much as 4-8”, therefore changing the overall mea­surement. Also, rolling the unit backwards will subtract measure­ment units.

Q: My wheel “wobbles” when I roll the unit – is this normal?

A: When the wheel starts to wobble, you should check two things: 1)

check that the flat spot inside the wheel hole and the flat spot on
the axle shaft are aligned; 2) check that the hub cover is on finger
tight (approximately 1/2 additional turn after the wheel hub
cover touches the wheel surface).
