CALIBRATION
In order to weigh accurately with an analytical balance, the balance must be calibrated after it has been
moved or if the room temperature has changed substantially.
You are also advised to carry out calibration routinely (before use every day).
Following calibration operations are possible with the ATX-R/ATY-R series.
Span calibration
Adjust to achieve correct balance sensitivity using either the internal weight (ATX-R
only) or the external weight.
Drift in the sensitivity is corrected.
Registering the internal weight (ATX-R only) or the external weight on , you can start operations
only by pressing .
*
The operation to calibrate the internal weight itself cannot be registered in
To calibrate the internal weight itself, refer to "Calibration of the Internal Weight (ATX-R Only)"
(^ page 58).
Use the following procedure to set the preferred operation for

Press for about 3 seconds.
This opens the calibration menu.

Select either "internal weight" or
"external weight".
