cities around the world. Mexico City (1.002102) is the lowest
and Oslo (0.998726) and Helsinki (1.001405) are the highest.
In general if your location is between the 45th parallel and
the equator the gravity correction is greater than 1.0.
Because the gravity is less at these attitudes you are adding,
for example 1.006 for an error that is .06%. For locations
between the 45th parallel and the North or South Pole your
correction factor is less than 1.0, for example .9994 for an
error that is -.06%.
NOTE: You must perform a C2 Calibration after setting
the Gravity Correction factor or the correction
factor won’t work.
NOTE: If you do not want to set the Gravity Correction
Factor go to Step 14.

Step 14. Press the Clear button to clear the entry. (See Fig. 5-
8)
FIG. 5-8 GRAVITY/CLEARING ENTRY
Step 15. From the Gravity Corrector Factors table select the
city correction factor closest to your location.
Step 16. Use the keypad to enter the selected value. In our
example we entered 1.002102 which is the cor-
rection factor for Mexico City. (See Fig. 5-9)

Step 17. Press the Enter button to save the setting.
Step 18. Press the down arrow button to move the cursor in
front of Do C2 Calibration. (See Fig. 5-10)
Step 19. Wait 15 seconds for the scale to settle.
Step 20. Press the Enter button to complete the Calibration.
