6.0 CALIBRATION
Calibration may be required when the balance is initially installed or moved to a new
location. Over time and use, mechanical deviations may occur so it is recommended
that you calibrate you balance regularly for peak performance.
Before calibrating your should make sure you have the correct weights. The weights
should be known to an accuracy that is appropriate for the balance being calibrated,
for example, OIML Class M1 type or ASTM E617 Class 4. If you do not have the
correct weights do not attempt calibration.

1) To enter into the calibration parameter turn the balance off, press [Tare] and
[Unit] keys at the same time and switch on the balance after 3 seconds
release [tare] and [unit] keys .
2) The display will show UnLOAD remove any objects from the pan.
3) Press the [Tare] key to enter a zero value.
4) The value last used for calibration will be displayed (see above table). To
select a different calibration weight, press the [Unit] key.
5) Once you have selected the calibration weight to be used 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 value the display will show
PASS and exit the calibration mode. If the calibration is not successful the
display will show FAIL and exit the calibration mode, if the calibration fails try
it again.
