GTESTING
Each TRAFx counter comes factory tested and ready to install. If installed according to instructions, paying careful
attention to the specified distances and other details, it is not normally necessary to test it. However, if desired, there are
several methods to test a counter.
1 WITH PC
With this method, counts immediately appear on your PC screen. This is useful when first learning about your counter
indoors, and also at installation locations, with a laptop. See below.
1. Confirm dock is in PC Mode
2. Connect: PC---cable(s)---dock---counter
3. Open TRAFx Communicator and click GO!
4. Enter “T” for TEST and press Enter ()
As a bike passes within the detection zone, or as you move a ferrous metal object (pliers,
hammer, stapler –but not a magnet or magnetic screwdriver) near the counter (approx. 10cm
/ 6in.), this should trigger a count which appears on the PC’s screen. Try it. Ferrous metal
objects (i.e., metals with iron content) distort the earth's magnetic field as they move through
it, and this triggers a count. Pure aluminum (non-alloy aluminum) will not be detected.
Counts appear on screen
Moving the counter (i.e., pointing it in different compass directions, or tilting it, or jiggling or
jolting it) will also cause counts to occur try this. This is because the earth's magnetic field
has different strengths for different directions and tilts, and the counter senses this.
If you move the counter too close to a computer or other electrical equipment, counts might
also occur. This is because certain types of electrical equipment create changing electro-
magnetic fields, which the counter detects. It’s also sensitive to very rapid temperature
change (e.g., direct sun).
5. To end the TEST, enter ZZZZ
6. To ERASE the test counts from the counter’s memory, enter “E”
2 WITHOUT PC
For this method, launch the counter and collect data for a few hours. Note that counting begins at START (top of the hour)
and that you must wait a full hour after START to download data.
Example:
10:40 - Launched counter > Status LIGHT blinks rapidly until START is reached
11:00 - Top of the hour (START) > counting begins > Detection LIGHT blinks upon count
12:00 - Okay to download data now.
In short, wait at least a few hours before downloading data.
3 WATCH DETECTION LIGHT
This is a variation of Method 2. As mentioned above, counting begins at START (normally top of the hour). After START,
the counter’s Detection LIGHT blinks when a count occurs (two blinks means two counts).
