2. Standard Functions
Output signal holding:
Output signals are held during manual
and auto calibrations by activation of
holding (turning “ON” its setting).
The values to be held are the ones just
before start calibration mode or setting
value.
It is selectable.
Indication of instantaneous values will
not be held.
Remote output holding:
Output signal is held at the latest value
or setting value by short-circuiting the
remote output holding input terminals.
Holding is maintained while the termi-
nals are short-circuited. Indication of
instantaneous values will not be held.
Switch ranges :
The switch ranges is available in manu-
al, auto, and remote modes. Only pre-
set switch method is effective.
Manual:
Allows range to switch by key operation.
Auto:
Allows range to switch from low to high
range when 90%FS or more is available
in the low range.
Allows range to switch from high to
low range when 80%FS or less is avail-
able in the low range.
Remote:
No-voltage contact input (for measur-
able components)
Allows range to switch via an external
signal when remote range switch input
is received.
When the contact input terminals for
each component are short-circuited,
the first range is selected, and it is
switched to the second range when the
terminals are open.
Range identification signal:
The present measuring range is identi-
fied by a contact signal.
The contact output terminals for each
component are short-circuited when
the first range is selected, and when
the second range is selected, the ter-
minals are open.
Auto calibration:
Auto calibration is carried out periodi-
cally at the preset cycle.
W h e n a s t a n d a r d g a s c y l i n d e r f o r
calibration and a solenoid valve for
opening/closing the gas flow line are
prepared externally 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.
Auto calibration cycle setting:
Auto calibration cycle is set.
Setting is variable within 1 to 99 hours (in
increments of 1 hour) or 1 to 40 days (in
increments of 1 day).
Gas flow time setting:
The time for flowing each calibration
gas in auto calibration is set.
Settable within 60 to 900 seconds (in
increments of 1 second)
Auto calibration remote start:
Auto calibration is carried out only once
according to an external input signal.
Calibration sequence is settable in the
same way as the general auto calibra-
tion.
Auto calibration is started by opening
the auto calibration remote start input
terminals after short-circuiting for 1.5
seconds or longer.
Auto zero calibration:
Auto zero calibration is carried out peri-
odically at the preset cycle.
This cycle is independent on “Auto cali-
bradion” cycle.
When zero calibration gas and solenoid
valve for opening/closing the calibration
gas flow line are prepared externally by
the customer, zero calibration will be
carried out with the solenoid valve drive
contact for zero calibration turned on/
off at the set auto zero calibration tim-
ing.
Auto zero calibration cycle setting:
Auto zero calibration cycle is set.
Setting is variable within 1 to 99
hours (in increments of 1 hour) or
Setting is variable within 1 to 40 days
(in increments of 1 day)
Gas flow time setting:
The timing for flowing zero gas in
auto zero calibration is set.
Settable 60 to 900 seconds (in incre-
ments of 1 second)
High/Low limit alarm:
Alarm contact output turns on when
measurement value reach to the preset
high or low limit alarm value.
Contacts close when the channel value
of each channel becomes larger than
the high alarm limit value or smaller
than the low alarm limit value.
Instrument error contact output:
Contacts close at occurrence of ana-
lyzer error No. 1, 3 or 10.
Calibration error contact output:
Contacts close at occurrence of manual
or auto calibration error (any of errors
No. 4 to 9).
Auto calibration status contact outputs:
Contacts close during auto calibration.
Pump ON/OFF contact output:
D u r i n g m e a s u r e m e n t , t h i s c o n t a c t
close. While calibration gas is flowing,
this contact open. This contact is con-
nected in power supply of pump, and
stop the sample gas while calibration
gas flowing.
