7. BALANCE CALIBRATION

To ensure high precision of weighing corrective factor in relation to standard mass

must be noted in the balance memory periodicaly – it is the balance calibration.

Calibration should be performed when:

- The weighing is started,

- Long breaks are between following measure series

- Temperature inside the balance changes more than: 0,8°C for CX (0,3°C

for balances with d=0,01mg) and 3°C for other balances

Kind of calibration:

- Internal automatic calibration

* started if temperature changes

* started if the time changes

- Manual internal calibration

* started by the balance keyboard

- Calibration made with external weight

* with declared mass which cannot be modificated

* with any mass which should be given before the calibration

process

In verified balances only automatic internal calibration and manual internal

calibration is accessible.

Perform the calibration when there is no load on the pan!
