7-2 Calibration Using the Internal Mass
(One-Touch
Calibration, only for the FZ-
CT
series )
This function calibrates the balance using the internal mass. The only operation required is to press
the CAL key. (The FX-CT series does not have the one-touch calibration function.)
Operation
1 Connect the AC adapter and warm up the balance for at least one hour with nothing on the
weighing pan.
2 Press the CAL key.
3 The balance displays
Calin
and performs calibration using the internal mass. Do not allow
vibration or drafts to affect the balance.
4 The balance displays end after calibration. If the “GLP output ( info )” parameter of the
function table is set to “
1
” or “
2
”, the balance displays
glp
and outputs “Calibration Report”
using the RS-232C interface. For details on the calibration report format, refer to “10-2 GLP
Report”.
5 The balance automatically returns to the weighing mode after calibration.
About the internal mass
The value of the internal mass may change due to corrosion or other damage caused by the
operating environment, or due to aging. The internal mass value can be corrected using an
external mass. To maintain the weighing accuracy, perform the internal mass value correction
periodically.
For details, refer to “7-6 Correcting the internal mass value: 1” and “7-7 Correcting the internal
mass value: 2”.
