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 calibration.
Auto calibration is started by opening the
auto calibration remote start input termi-
nals after short-circuiting for 1.5 seconds
or longer.
Auto zero calibration: Auto zero calibration is carried out
periodically at the preset cycle.
This cycle is independent of “Auto
calibration” 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 car-
ried out with the solenoid valve drive con-
tact for zero calibration turned on/off at
the set auto zero calibration timing.
Auto zero calibration cycle setting:
Auto zero calibration cycle is set.
