*1 If the jet or the cable is damaged, contact your Shimadzu representative for replacement.
*2 If the gas supply pressure is fluctuating due to the failure of the pressure regulator of gas cylinder, it needs to be
repaired or replaced. Contact your Shimadzu representative.

GC display (In cases where in the setting screen is reinitialized each time power is turned on)
For GC-2014, various analysis conditions are stored, and during installation environmental settings are set by
our field engineer and stored in the GC’s memory. When the power of the GC main unit is turned off, these
parameters are backed up in the memory by the built-in battery (CPU battery). However, because the CPU
battery is a consumable, the supplied voltage decreases with long-term use.
The battery life / replacement frequency for the CPU battery life is about 5 years. The error message "Battery
voltage error" will be displayed when the battery is exhausted. If you continue to use the GC in this state, the
memory will be initialized at startup and all parameters, including analysis conditions, will be reset to the initial
values; this will be shown in English on the GC display. In such an event, you will need to reconfigure all
parameters such as GC environmental setting parameters and analysis conditions.
For this reason, we suggest as a rough guide, to replace the batteries every five years. Please contact our
sales office, distributor or service representative. We will assign a field engineer to visit your location.
Linear range is
extremely narrow.
You have specified the analog
signal polarity as "Linear" in
connection with C-R8A and C-
R7A (Plus).
Specify as "Wide".
You have specified the analog
signal polarity as "Wide" in
other connections than the
above (e.g. C-R6A, etc.).
Specify as "Linear".
You have not zero-calibrated
properly at the connection with
C-R8A and C-R7A (Plus).
Re-execute the zero calibration.
