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 8.5, earlier in this manual).
• In Section 8.4, Output Contact Setup, earlier in this manual, set the contact used as the
blow back switch beforehand.
• 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 or maintenance service. If automatic blow back
reaches the preset start time during calibration or maintenance service, blow back will be
executed after completing the calibration or maintenance service and after the equipment
returns to the measurement mode.
• If automatic blow back reaches the preset start time during semi-automatic blow back, the
current automatic blow back 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 blow back will be executed.
