ECONOMY COUNTING SCALE
17
GRAVITY ADJUSTMENT
This scale has built-in compensation provisions to allow factory calibration, with destination correction
capabilities, to compensate for variances on gravitational forces. If the scale is subjected to a different
gravitational force at its destination location, this can be compensated for electronically by adjusting the geo
value. The GEO value has 32 settings. The GEO value for any world location can be found in the GEO
Value Table in the Appendix of this manual (See page 19.) as long as the geographical coordinates and
elevation above sea level is known.
Select S3=1 and press
to enter the GEO sub-menu. The GEO value can be changed as shown below by
pressing
.
CALIBRATION
To enter the calibration sub-menu, select S4=1. The scale can be calibrated in two modes, the full range
calibration and the linearity calibration.
Example: 6 lb full range calibration (S4.1=0)
The scale displays SP 6, where 6 means the capacity is 6 lb.
Pressing
can select the capacity. Press the key to continue.
The Wt window displays 2----. Press
to capture zero weight; the
scale counts down from 5..
The Wt window displays L---3. Put 3lb weight on the scale. Press the
key
to calibrate. The scale counts down from 5 with a display of H-
--5, H---4, H---3, etc.
Display E 0 and press
to switch to E 1. Press to save the
result. The calibration is complete and the scale restarts.
