Backup Battery Replacement
Calibration Due Control (the calibration period)
The next day that calibration is necessary is set as a period after the previous calibration date. This
setting can be set to a value in the range of 3 months to 36 months, and it can also be set to infinity.
Calibration Protection (notification of when the calibration period
elapses)
You can set how the TOS5300 Series will operate when the specified number of days after
calibration have elapsed.
When this calibration period elapses, the message “Calibration Protection (Code:0x0002)” will be
displayed when you turn the TOS5300 Series on.
If Calibration Protection is set to ON, the TOS5300 Series displays the message, and then switches to
the PROTECTION state. In this state, you cannot use the TOS5300 Series.

To continue using the TOS5300 Series, press STOP and then CONFIG (SHIFT+FUNCTION) to display
the configuration setup screen. Next, select 3.Date and Time, and then set Calibration Protection to
OFF.
If you set Calibration Protection to OFF, you can continue using the TOS5300 Series by pressing
STOP to clear the PROTECTION state.
Calibration
The TOS5300 Series is calibrated before shipment. To maintain long-term performance, we
recommend periodic calibration.
To perform periodic calibration, set the calibration period (Calibration Due Control). To have your
TOS5300 Series calibrated, contact your Kikusui agent or distributor.
Backup Battery Replacement
The TOS5300 Series uses a lithium battery for memory backup.
When the battery is low, the TOS5300 Series cannot store data such as test conditions. (Battery life
varies depending on the environment.) As a guideline, we recommend that the battery be replaced
once every three years. You can also have the TOS5300 Series inspected and cleaned at the same
time.
You must open the cover to replace the backup battery. For battery replacement, contact your
Kikusui agent or distributor.
When this setting is set to
ON, the screen of the
TOS5300 Series remains in
the PROTECTION state even
if you press STOP. Press
CONFIG (SHIFT+FUNCTION)
to display the configuration
setup screen.
