Gravity Compensation

This feature is used to compensate for the variance in gravitational pull from one location to another and is

available for the 120 Plus. To calibrate with gravity compensation, the GRAVADJ parameter must be set to ON,

and the LATITD (latitude in degree) and ELEVTN (elevation in meters, relative to sea level) parameters

set before calibrating the 120 Plus.

If the indicator is later installed at a different location, gravity compensation can be applied to a pre-calibrated

120 Plus by adjusting the LATITD and ELEVTN parameters.

Gravity is greater at the poles than at the equator and decreases with increase in altitude. The effect of

gravity at any given location can be calculated using the following formula:-

CAL

= 9.80632 - 0.0258

Cos

(0.0349065850

CAL

gOpa = 9.80632 - 0.0258

Cos

) + 0.00003

Cos

(0.00698131701

) - 0.00000293

(EQ 2)

Where

Ø =

Magog: = 45° and h = 222m, Taipei: = 23° and h = 10m
