Interval time..
Within the SETUP CALIBRATION menu the
INTERVAL TIME.. line opens the following
screen:
Two time intervals may be entered:
ZeroAll: This entry species intervals for
zero calibrations only! If there is an entry for
the ZSCalAll too, the instrument will carry
out additional zero calibrations based on the
ZSCalAll interval.
ZSCalAll: This is the interval to elapse before
the analyzer automatically starts a complete
calibration procedure consisting of a zero
calibration followed by a span calibration.
Entering 0 disables the related calibration pro-
cedure. Setup the time intervals depending
on your applicational needs.
By default, the time interval countdown starts
when a value is entered. If you want to start
the rst calibration earlier than the interval
specied, enter the menu AUTOCAL IN.
