HOW TO USE YOUR NEW MAPWHEEL
MAP WHEEL INSTRUCTIONSMAP WHEEL INSTRUCTIONS
Congratulations on purchasing MapWheel, the finest map measure
available. MapWheel is a simple, fast and accurate way to measure
distances on maps, whether in straight lines or along curves. Just
set MapWheel's scale to match the map, then roll MapWheel along
the route you want to measure. The distance is displayed instantly.
To begin using your MapWheel, first put in the two AAA batteries.
Make sure the batteries face the correct way as shown on the label.
MapWheel will turn on ready to use.
When you are done with your MapWheel, set it aside and it will
turn off automatically after about seven minutes. Press any button
to turn your MapWheel back on.
MAKING A MEASUREMENTMAKING A MEASUREMENT
BUILT-IN SCALESBUILT-IN SCALES
Before making a measurement, you must set your MapWheel's
scale to match the map. There are three ways to do this as
described in the following sections.
Once you have set the scale, roll your MapWheel on the map to
make a measurement. To start over, press the CLEAR button
to reset MapWheel to zero.
MapWheel reads out in either miles (display shows "MI"), kilometers
("KM") or Nautical Miles ("NM"). Press the MI/KM/NM button
to change the readout. When you change from one readout to
another, the measurement is converted.
For common scales, simply use one of MapWheel's nineteen
standard built-in scales. These are shown on the map like this:
1 : 10,000 1 : 24,000 1 : 50,000 1 : 100,000 1 : 1,000,000
1 : 12,000 1 : 25,000 1 : 62,500 1 : 125,000 1 : 2,000,000
1 : 14,400 1 : 31,680 1 : 63,360 1 : 250,000 1 : 2,500,000
1 : 20,000 1 : 36,000 1 : 500,000 1 : 5,000,000
Press the UP or DOWN button and the scale is displayed
in place of the measurement. Continue to press or until
you find the scale which matches your map. Press to begin
measuring.
(Note – if the map's scale is shown in miles per inch, see specified section)
A reminder of the MapWheel's scale always appears in the lower
left part of the display. The reminder shows the scale but without
the last three digits. For example, if the MapWheel is set to
1:24,000, a small 1:24 appears in the lower left part of the display.
USER SCALESUSER SCALES
AUTO-SCALEAUTO-SCALE
If the map's scale is not on the list above, you can enter it into your
MapWheel manually. To do so, press the USER button. The
scale appears on the display with one digit flashing. Use the
down arrow button to move the flashing digit right or the
button to move the flashing digit left. Use the up arrow
button to raise each digit or use the button to lower the
digit. When the scale is correct, press the button. You are
now ready to measure in the new scale.
When you enter your own user scale, it is put into the list of scales
in numerical order. For example, if you enter a scale of 1:40,000, it
will appear in the list between 1:36,000 and 1:50,000. You can enter
up to three user scales. If you enter more than three user scales,
the oldest one drops off the list and only the three most recent user
scales are kept.
The user scales remain in the MapWheel even if it turns off.
However, if you change the batteries, the user scales are erased.
If your map does not show a scale or if the map has been reduced or
enlarged, you can set the scale from a known distance on the map.
To do this, press the AUTO button. A picture of the
MapWheel's wheel will appear on the display along with a row of
digits with one digit flashing. Enter the known distance using the
DOWN button to move the flashing digit right or the
button to move the flashing digit left. Use the UP button to
raise each digit or use the button to lower the digit. When
the known distance is shown correctly, roll the MapWheel along this
distance and press the button. You are now ready to make
measurements.
For greatest accuracy, use the longest distance possible as your
reference.
Note that the scale that was calculated by auto-scale is not
automatically entered into the list of scales, so if you change scales,
it will be lost. If you want to save the scale, press the button
and then the button.
MILES PER INCHMILES PER INCH
COUNTERCOUNTER
ADDERADDER
Some maps show the scale in miles per inch instead of the more
common ratio form. If you wish, you may set the MapWheel to
show scales in miles per inch. To do this, first set the MapWheel to
read out in miles ("MI"). Then press the or button to
display the scale. Press the MI/KM/NM button to change
between miles per inch and ratio. The scale factor will show "1".
When the MapWheel is set to show scales in miles per inch, the
USER button also works to enter the scale in miles per inch.
Simply follow the instructions in the section on "User Scales".
The MapWheel has a special counter button on the probe tip
near the wheel (marked "+1"). Use this button to count individual
items on the map.
Press the counter button to add one to the count in the lower
right of the display. Press the button to zero the count.
The count is independent of the measurement and you may use
the counter button while the wheel is rolling or stopped. The
count goes up to a maximum of 999.
The MapWheel also has a special "adder" button on the probe
tip (marked "+K"). Use this button to add a constant distance to the
measurement. This is useful if, for example, you wish to add a few
miles to your trip distance for every stop.
To see the adder constant, press and hold the adder button for
two seconds. The display shows the adder constant with one digit
flashing. Press to leave the constant as it is or change the
constant using the and arrow buttons as described for
"auto scale", then press the button.
Every time you press the adder button, the constant is added
to the measurement. You may use the adder button while the
wheel is rolling or stopped.
