9.2.1 Mode
There are three calibration modes (for zero and span calibration): manual mode, semi-
auto mode (started from the display or started by contact input) using preset calibration
time and stabilization (settling) time, and autocalibration at preset intervals. Restrictions
related to each mode are described here.
- When [Manual Mode] is selected
In this mode, only Manual calibration can be performed. (Contact input used to start
semi-auto calibration has no effect). Autocalibration does not start at autocalibration
start time.
- When [Semi-Auto Mode] is selected.
In this mode, manual calibration or semi-auto calibration can be performed.
Autocalibration does not start at autocalibration start time.
- When [Auto Mode] is selected.
Any calibration mode is valid.
CAUTION

fore, If the mode of Indication Check is set to [Auto], you cannot set the mode of
Calibration to [Auto], and vice versa.
