Wodometer Instructions

Congratulations — you've reached a new level of obsessiveness when it comes to monitoring your critter! Now you can easily measure how far and how fast your little pal is going.

The Wodometer consists of a Sigma Bike Computer calibrated for a Wodent Wheel and a sticky-back magnet for mounting on the back of a wheel. The bike computer has been programmed to display the speed and distance for a particular size Wodent Wheel. The sticker on the back indicates the wheel size. If you wish to program for a different wheel size, or if you replace the battery (it should last about three years), refer to “Programming” below.

Installation

Installation is fairly simple. First, pick a nice flat spot for the magnet on the Wodent Wheel back panel. Make sure the spot is clean and dry, remove the backing paper from the double-sticky tape on the back of the magnet, and firmly press the magnet onto the chosen spot. (Avoid letting the sticky-back tape get wet. If it looses its stickiness, similar tape can be found in office supply stores. If you decide to bolt the magnet to the panel, be sure that no protrusions create a hazard — inside the wheel or out.)

Next, using one of the enclosed rubber o-rings, attach the sensor to the vertical portion of the wheel support stand and position the rounded edge of the sensor (the part with “Sigma” printed on it) so the magnet clears it by about an eighth of an inch or less as the wheel turns. If you need to get the sensor closer to the magnet, insert thin spacers (such as dimes) between the stand and the sensor.

Finally, install the wheel so it can't shift and the back of the wheel is near a wall of the cage. Route the wire so there's no way that your critter can get to it — or the sensor. This is the most important part of the installation — critters WILL chew the wire if they can get to it. This probably won't hurt them unless they scarf down an awful lot, but it won't do them any good and it'll certainly wreck the Wodometer. (If this happens, you can repair it by replacing the leads — not fun.)

The Display

The display is divided into two parts: the top part indicates the speed in either mph or kmh. The bottom part of the display indicates the time, the total distance traveled (odometer), the distance traveled on the current trip, and the time taken on the current trip (stopwatch function). The “current trip” settings are re-zeroed after 4 hours of no activity. The bottom display has several different modes that are controlled by pressing the red MODE button on the bottom of the computer.

Programming

The Wodometer is shipped calibrated to indicate miles and mph for the wheel size requested. If you change wheels or replace the battery you can set the calibration in the following manner:

First, remove the back cover of the bike computer (the part where the wire is attached) by unscrewing it about 1/8 turn. This exposes the back of the module. (At this point you can also see where the battery is located.) Looking at the back of the module, you can see a tiny little soft-rubber dimple in the upper-right corner with a circled “S” next to it. This dimple is actually a SET button that is best pressed by using a ball-point pen. (If you use something sharp like a pencil point, you'll probably poke a hole in the soft rubber cover.)

Any of the display values or the wheel size can be changed by pushing and holding the SET button for about three seconds when the display is in the appropriate mode. To get the display in the right mode for setting the wheel size, push the red MODE button until there's a little “M” in a black box in the lower-left corner of the display. Now, flip the module over and press and hold that SET button for about 3 seconds.

The display will blink “SET” and “MPH” in the upper-right corner. By pressing the red MODE button, you can change that to KMH if you prefer using kilometers. After selecting either MPH or KMH, press the little SET button again. The bottom part of the display will now show a four-digit number with the left-most digit blinking. Repeatedly pressing the MODE button will cycle that digit from 0 through 3. When you get the desired value, pressing SET will store the value and the next digit will start blinking and the red MODE button will cycle it 0 through 9. After storing all four digits and pressing SET the final time, the computer will exit the programming mode.

The value you want for the four-digit number depends on which wheel you have and whether you want kilometers or miles as follows:

Junior Wheel Senior Wheel Wobust Wheel

Miles: 0390 0534 0574

Kilometers: 0629 0860 0924

	Junior Wheel	Senior Wheel	Wobust Wheel
Miles:	0390	0534	0574
Kilometers:	0629	0860	0924
