Check if the calibration mass is wrong. Try calibrating the balance
again using a correct calibration mass.
•
If it is still a problem then check if the value displayed is much more
or less than the actual weight. If the difference is more than 2% of
the calibration weight value, adjust the span potentiometer as shown
below.
•
Remove the plastic plug on the right hand side of the balance. There
is a hole through which you will find an adjustable potentiometer.
Use a small screwdriver to adjust the value displayed. To increase
the value displayed, turn the screw on the potentiometer clockwise.
To decrease the value displayed, please turn the screw anti-
clockwise.
•
When the value displayed is approximately the actual weight, press
the
[Cal] key to calibrate the balance again.
4.2 CALIBRATION CHECK
•
To verify whether the balance is calibrated or not, place the
calibration mass on to the centre of the pan gently when 0.0g is
displayed.
•
It is calibrated if the correct weight is displayed. Remove the weight
from the pan.
•
If the value displayed is more or less than ± 0.1g from the standard
repeat the calibration procedure.
