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 the voltage
is input to the terminals. Indication of
instantaneous values are not held.

range is selected.
Auto calibration:
Auto calibration is carried out periodically
at the preset cycle.

tion and a solenoid valve for opening/

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).

Settable within 60 to 900 seconds (in
increments of 1 second)
Auto calibration remote start:
Auto calibration starts by opening the auto
calibration remote start input terminal
after short circuiting for 1.5 sec or longer.
Auto calibration starts when contacts
open.
Auto zero calibration:
Auto zero calibration is carried out peri-
odically at the preset cycle.
This cycle is independent from “Auto
calibration” cycle.

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.
