2. standard Functions
output signal holding:
Output signals are held during manual
and auto calibrations by activation of
holding (turning “ON” its setting).
The output 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.
switch ranges:
The switch ranges function is available in
manual, auto, and remote modes. Only
preset switch method is effective.
Manual: Allows range to switch by key opera-
tion.
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 available
in the low range.
Remote: Voltage contact input (for measurable
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 input voltage, the
first range is selected, and it is switched
to the second range when the terminals
are open.
3. optional Functions
Remote output holding:
Output signal is held at the latest value or
setting value by voltage input the remote
output holding input terminals.
Holding is maintained while the voltage
input the terminals. Indication of instan-
taneous values will not be held.
Range identification signal:
The present measuring range is identified
by a contact signal.
The contact output terminals for each
component turn on when the first range
is selected, and when the second range
is selected, the terminals are open.
Auto calibration:
Auto calibration is carried out periodically
at the preset cycle.
When a standard gas cylinder for calibra-
tion and a solenoid valve for opening/clos-
ing the gas flow line are prepared exter-
nally 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 termi-
nals after input voltage 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-
bration” 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 timing.
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 vari-
able 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 increments
of 1 second)
High/low limit alarm:
Alarm contact output turns on when mea-
surement value reach the preset high or
low limit alarm value.
Contacts turn on when the channel 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 calibra-
tion.
