7 Calibrating the Scale
23
ZERO: The Zero value is the current Zero value for the scale. It should be +10% from the calibrated
zero; however, if you change and save this value, it becomes the calibrated zero value. While the
cursor is on the Zero field, you can change this value but, you must press the ENTER key twice for it to
take effect. Lowering the value will lower the weight; increasing the value will increase the weight.
While the cursor is on the Zero field, can also press the TEST key to bring the weight to 0.000. This also has
the effect of changing the Zero value.
If you wish to save your changes, press the SAVE key at any time or the ENTER key while the
cursor is on the last field of the screen. If you wish to undo your changes, press the ESC key at anytime.
Once you leave this screen, the display will return to the previous screen (Calibration Menu.)
NOTE: Any changes made here will affect the NTEP Audit Trail counters (CAL counter only.)
7.4 Gravity Constant
NUMERIC
< GRAVITY CONSTANTS >
At Calibration Place : 9.7994
At Using Place : [9.8024]
Once at the Main menu
screen, press the 3 key. The
Gravity Constants screen will
appear:
If the Calibration Place & the
Using Place values are the same,
it means that the scale was
calibrated at that constant’s corresponding location(s) and thus no compensation takes place. If these
are different, this implies that the scale was calibrated at some other location than the Using Place
value. In this case compensation takes place.
The purpose of this function is to allow you to calibrate the scale in one location, say New York, and
then ship it to another location, say Panama, where you change the Using Place value from 9.8024 to
9.7814. This will compensate for the difference in gravity at the 2 locations and so you need not
recalibrate the scale. Press ENTER or SAVE to save changes or ESC to quit without changing.
