(3) o
2
sensor input: External input connector (A/i
)
Input signal:
External zirconia O
2
analyzer : Zirconia O
2
sensor signal (Fuji ZFK7 output)
External O
2
analyzer
: 0 to 1 V DC (DC input resistor of 1MΩ or more)
●
It is used when the external zirconia O
2
analyzer or the external O
2
analyzer is specified as
order.
●
Connect the dedicated connector (accessory) to the output of the external Zirconia analyzer or
the external O
2
analyzer prepared separately.
●
In case of an external O
2
analyzer, input a signal of 0 to 1 V DC with respect to O
2
full scale
of the analyzer. The O
2
concentration display, output, and O
2
correction can be performed.
●
Do not connect when the built-in O
2
analyzer is installed.
O
2
sensor input is not isolated. It is recommended to isolate when an external O
2
analyzer is
installed apart from this analyzer. Zirconia O
2
sensor (Fuji ZFK7) should be installed at a loca-
tion that is as close to this instrument as possible.
