Calibration by 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
a cceleration due to gravity.
The scale is calibrated at 9.798 m/sec
acceleration at your location is not same, calibrate the scale by
compensating for the gravity acceleration. (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. 9. 7 98 will be displayed. Press the [RE-ZERO]
key. The decimal point will move and the last digit will be selected. Select
a digit to be changed with the [UNITS] key. The first digit after decimal
point is the selected digit.
3. Set the value.
Change the value of the selected digit by pressing the [RE-ZERO] key.
4. Save the value in memory.
While pressing the [UNITS] key, press the [RE-ZERO] key to save the
value. Then end will be displayed.
