Gravity compensation
If you have calibration weights at the capacity of the scale, you can calibrate
the scale with the weights instead of compensating for acceleration due to
gravity.
The scale was calibrated at 9.798 m/sec
2
, at the factory. If the acceleration due
to gravity at your location is not same, compensate the scale by adjusting the
acceleration due to gravity. (Refer “The Value of Gravity at Various Locations”
and “World Map” and find your location value.)
1. Enter calibration mode.
Press the [ON/OFF] key to turn the power off. While pressing both the
[RE-ZERO] key and the [UNITS] key, press the [ON/OFF] key. Cal will
be displayed.
2. Select a digit to be changed.
Press the [UNITS] key. The previously set value, for example 979,8 , will
be displayed. A digit after the comma “,” will be changed by pressing the
[RE-ZERO] key. Press the [UNITS] key to move the comma “,” and select
a digit to be changed.
3. Set the new value
Change the value of the gravity acceleration using the [RE-ZERO] and
[UNITS] keys.
4. Save the value in memory.
Press and hold the [UNITS] key until end is displayed. The scale will
automatically return to the weighing mode.
