CALIBRATION

Calibration may be required when the scale is initially installed or moved to a new
location.
Over time and use, mechanical deviations may occur so it is recommended that you
calibrate your scale regularly.
Before calibrating you should make sure you have a suitable weight. The weights should
be known to an accuracy that is appropriate for the balance being calibrated, for
example, OIML Class F1 type or ASTM E617 Class 2. If you do not have proper weights
do not attempt calibration.
1) To enter into the calibration parameter turn the power off, switch the scale on and
during the counting up sequence press the [TARE] and [STORE] keys together,
then release these keys.
2) The display will show UnLOAD, remove any weight from the pan.
3) Press the [TARE] key, the weight value used for the last calibration will be
displayed.
4) To select a different calibration weight value press the [STORE] key. This will
cycle you through the weight values that can be selected for your calibration,
values available are 500g, 1000g and 1500g.
5) Once you have selected the weight to use press the [TARE] key.
6) LOAD will be displayed, place the calibration weight on the pan.
7) Once the stable sign is shown press the [TARE] key.
8) If the weight is within 5% of the last calibration the display will show PASS, exit the
calibration routine and return to normal weighing mode. If the calibration is not
successful the display will show FAIL and exit the routine, if the calibration fails try
again.
