CALIBRATION
In order to weigh accurately with an electronic 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).
Two kinds of calibration operation are possible with the TW/TX/TXB series: "span calibration" and the
"calibration check", and for each of them you can select the use of either the internal weight (TW only) or
the external weight.
By registering either of these for
, the registered operation can be started by just pressing
Span calibration
Adjust to achieve correct balance sensitivity using either the internal weight (TW only)
or the external weight.
Drift in the sensitivity is corrected (default setting).
Calibration check
Investigate the drift in the balance’s sensitivity by using either the internal weight (TW
only) or the external weight.
*
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 (TW Only)"

Use the following procedure to set the preferred operation for

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

Select either "span calibration" or
"calibration check".
