7. CALIBRATION
This function adjusts the scale for accurate weighing.
Perform calibration in the following cases.
When the scale is first used.
When the scale has been moved.
When the ambient environment
has changed.
For regular calibration.
The CAL switch
is inside
7-1. Preparation
Prepare a calibration weight (conforming to OIML class F1)
before starting calibration.
A calibration weight is not required for performing zero
calibration only.
When a calibration weight is not available, the gravity
acceleration correction can be performed to compensate the
scale.
1. Turn the power ON and warm up the scale for at least
30 minutes with nothing on the pan.
2. Press and hold the CAL switch until
Cal
appears, and release the switch.
3.
Cal 0
appears.
To change the calibration weight value, proceed to
Step 4.
To use the calibration weight value stored in memory or
perform zero calibration only, proceed to Step 5.
4. Press the PRINT key. The display shows the
calibration weight value in “grams” that is stored in
memory. Use the following keys to change the value.
MODE key
To select the digit to change the
value. The selected digit blinks.
RE-ZERO key To set the value of the selected
digit.
PRINT key
To store the value and return to
Step 3.
Use a calibration weight of more than 2/3 of the
weighing capacity (of the R2 range for the EK-30KL).
The calibration weight value is stored in memory
even after the power is turned OFF.
