Press the CAL switch to enter the calibration mode.
Then
Cal
is displayed.
Step 2 Select one of the following items to calibrate the scale.
ENTER : To calibrate using the calibration weight (Refer to “12.2. Calibration Using the Weight”).
MODE : To calibrate using the gravity acceleration value setting (Refer to “12.3. Setting the
Gravity Acceleration”).
12.2. Calibration Using the Weight
Calibration of the Zero Point
Step 1 Keep the display turned on for at least 30 minutes to warm up
the scale. Keep in mind the items of “4.1. Precautions for
Installing the Scale”.
Step 2 Press the ENTER key while
Cal
is displayed to display
Cal 0
.
Step 3
Confirm that nothing is placed on the weighing pan.
Wait for the stability indicator to be displayed.
Press the ENTER key.
The scale stores the current condition as the zero point.
Step 4 Calibration of the zero point is finished. To exit the
calibration mode at this step, press the CAL switch
.
The
display will then be turned off
