SCALE SETUP, CONT.
! (CALIBRATION)
The display will show ! and the current setting 06. If the scale has been previously
calibrated and you wish to skip calibration and proceed to the ;($ (Scale Model) prompt,
press the
key and the previous calibration will be retained.
To begin calibration, press the
× key to select YES and then press the key. After
pressing the
key, the display will change to !#3.
!#3 (LOAD CALIBRATION WEIGHT)
With the display showing !#3, perform the following steps:
1. Make certain the scale platform is empty and free of debris.
2. Place the desired amount of calibrated test weights on the scale platform. A minimum of
50% of the scale's capacity is required. However, 70% to 100% is recommended.
3. Press the
key.
4. If the value displayed is acceptable, press the
key again. Otherwise, determine the
exact amount of test weight placed on the scale platform and then using the × or Ø
keys select the test weight amount.
5. Verify that the numbers selected are the same as the amount of the test weight and
then press the
key.
6. Starting at the left and proceeding right, a series of dashes will appear on the display.
The dashes will stay on the display momentarily, then disappear, after which the display
will proceed to the next prompt.
'0!3 (UNLOAD CALIBRATION WEIGHT)
After a moment, the display will change to '0!3.
1. Remove the test weights from the scale platform and then press the
key.
2. Starting at the left and proceeding right, a series of dashes will appear on the display.
The dashes will stay on the display momentarily, then disappear, after which the
calibration factor will be saved, and the display will proceed to the next prompt.
IMPORTANT: During the time the dashes are appearing on the display,
ensure that the loaded (or empty) scale is stable.
9< (Gravity Compensation)
Gravity compensation accounts for latitudes and elevations that are different from where the
scale was calibrated. To calculate the value for this parameter, use the gravitational
constant of the location where the scale was calibrated divided by the gravitational constant
of where the scale will be installed:
Gravitational Constant (Calibration location)
---------------------------------------------------------- = value
Gravitational Constant (Operation location)
This should give you a value close to 1 that you can enter to compensate for variation in
gravity due to elevation/latitude.
The display will show 9< and the current setting. If the value displayed is acceptable,
press the
key. Otherwise, press the × or Ø keys to select a new value and then press
the key to save it and proceed to the next prompt.
Allowable values for 9< are 0.000 to 2.000.
NOTE: The default value is 1.000, which means there is no gravity compensation.
