Using an External Calibration Weight:
Calibration is required when the weighing scale is initially installed or if the scale is
moved to a substantial distance from the original location. Single segment calibration
(recommended):
Press the “Zero” button and turn the scale back on simultaneously.
The Scale will count down and it will go to the calibration menu. Then Select the
calibration unit (kg. or lb.).To change the calibration unit press the “sample”
button.
Check to make sure that the scale is stabilized then press the “Zero” button,
Once it starts flashing “0”, key in how many test weights you will use to calibrate
the scale. Then wait for the scale to stabilize.
Place the weights you will use to calibrate on the platform. Once the scale is
stabilized press the “Zero” button. Wait for a line of “0”s to show on the scale.
Calibration is complete, turn off the scale and the settings will be saved.
Remove the weights and turn on the scale for normal operations.
Linearity Calibration
(For scale technician or factory use)
Press and hold the Tare key and then turn on the scale. The display will show
Line on the first line, CAL-0 (flashing) on the second line and AS value on the third
line.
When the AD value is stable, press Zero to calibrate Zero. After 2 or 3
seconds, the second line will sow 1, 0000. (Ex. LCT-7)
Place a 1 kg. weight on the platter and press “Zero” when the stable A/D value
is displayed. After 2 or 3 seconds, the display 2.0000.
Place a 2 kg. weight on the platter and press “Zero” when the stable A/D value
is displayed. After 2 or 3 seconds, the display will show 3.0000.
Place a 3 kg. weight on the platter and press “Zero” when the stable A/D value
is displayed. After 2 or 3 seconds, the display will show 0.0000. Calibration is now
complete.
Pres the power key twice, and place a weight on the platter to ensure weighing
is correct. If not, repeat the above steps.
