13.5.1 INTERNAL CALIBRATION MASS ADJUSTMENT
Balance model Internal Calibration mass (approx.)
PW 124 100g
PW 184 100g
PW 214 100g
PW 254 100g
NOTE: The value of the internal mass is not an exact number, such as 100g.
It must be set by comparing with an external mass. The exact value can be
set, provided this feature is enabled at the factory.
PROCEDURE
• Make sure the balance is level and has been ON for 4 hours or more at
a stable temperature.
• Calibrate the balance twice. This helps to reduce any stresses in the
mechanics.
• To verify the accuracy of this internal calibration, place an external
mass approximately equal to the same internal calibration mass.
Record the result.
