Within the SETUP CALIBRATION menu the
"INTERVAL TIME.." line opens the following
screen:
Two time intervals may be entered:
ZeroCal: This entry specifies intervals for zero
calibrations only! If there is an entry for the
SpanCal too, the instruments will carry out ad-
ditional zero calibrations based on the ZeroCal
interval.
SpanCal: This is the interval (time between
two calibration procedures) to elapse before
the analyzer automatically starts a complete
calibration procedure consisting of a zero
calibration followed by a span calibration.
Setup the time intervals depending on your
applicational needs.
Time intervall starts when the value is entered.
Entering "0" disables the related autocali-
bration.
