How do you Calibrate a timex digital compass?

Answer 1

Go to the Timex web site and look up "manuals". They have enough of a listing to figure out the correct procedure for your device. Here is the URL for the page I'm speaking of. http://assets.timex.com/manuals/?timexBrand=core I own the Expedition Adventure Tech Digital Compass Watch, and the following instructions will calibrate its compass. A. To calibrate for magnetic north, press and hold HEADING (from TIME OF DAY mode only) until ROTATE WATCH TWICE appears in the display. B. Hold watch level relative to the horizon (on your wrist, in your palm, or on a non-metallic table). Rotate watch slowly two complete rotations (taking at least fifteen seconds per rotation). Press MODE when finished. (Two-step calibration: Upon completion of STEP A, press HEADING. Do not enter a value for declination angle. While in TIME OF DAY mode, press HEADING. A heading will be displayed. Noting heading value, adjust watch position for heading of 150 degrees. Initiate calibration by pressing and holding HEADING until ROTATE WATCH Twice is displayed. Repeat calibration procedure as discussed in Step A. At completion of calibration proceed normally to Step C.) C. Watch will then call for you to enter DECLINATION. Pressing HEADING will exit calibration mode and leave watch set to measure magnetic north. Entering a declination value instead will allow the watch to point to true north, by adjusting for the angle, which varies for different spots on the globe. D. To set watch for true north, enter declination angle for your location from the chart below. Press START to advance flashing TENS OF DEGREES, press MODE to select DEGREES, then START to advance. Press MODE to select direction, then START to switch between E and W. Press HEADING to exit calibration and save new values. TABLE 1.
