NOTE
• If the blow back is executed with an input contact, it must be preset in the Input contact
settings (for more details, see Section "8.6 Input Contact Settings").
• Set the Output contact used as the blowback switch (for more details, see Section "8.5
Output Contact Setup").
• Do not set any other function for the contact used as the blow back switch.
Otherwise, blow back may be activated when the contact is closed by any other function.
• No blow back is executed during calibration. If the start time of the automatic blow back
comes, the calibration ends and the blow back will be executed after the instrument returns
to the measurement status.
• If the start time of the automatic blow back comes during a maintenance mode or semi-auto
blow back, the auto blow back of this time will not be executed.
• If you set the blow back interval at 000 days, 00 hours, only the first blow back is then
executed. No subsequent blow backs will be executed.
• If a past date is set for the Start time, no automatic blow back will be executed.
