2. Standard Functions
Output signal holding:
Output signals are held unchanged during
manual and auto calibrations by activation
of holding (turning "ON" its setting).
The values held are those just before
start calibration mode or setting value.
Usage is selectable.
Indication of instantaneous values will
not be held.
Switch ranges: The switch ranges function is available in
manual, auto, and remote modes. Only
preset switch method is effective.

3. Optional Functions
Remote output holding:
Output signal is held at the last value
or preset value by voltage input to the
remote output holding input terminals.
Holding is maintained while is voltage
input to the terminals. Indication of in-
stantaneous values are not held.

Auto calibration:
at the preset cycle.
When a standard gas cylinder for calibra-
tion and a solenoid valve for opening/
ternally by the customer, calibration will be
carried out with the solenoid valve drive
contacts for zero calibration and each
span calibration turned on/off sequentially
at the set auto calibration timing.

High/low limit alarm:
measurement value reaches the preset
high or low limit alarm value.
Contacts close when the instantaneous
value of each channel exceeds the high
alarm limit value or falls below the low
alarm limit value.
Instrument error contact output:
Contacts turn on at occurrence of analyzer
error No. 1, 2, 3 or 10.
Calibration error contact output:
Contacts turn on at occurrence of manual
or auto calibration error (any of errors No.
4 to 9).
Auto calibration status contact outputs:
Contacts turn on during auto calibration.
