If the power switch is turned off, this will be treated as a power outage, and “AC” will be
displayed in the error item field.
Power Outages
If a power outage occurs during operation, the product will turn off and stop operating. The
remaining sampling will continue after power is restored.
E.g.) If an 8 hour sampling period has been set, and a 1 hour power outage occurring during
this time, sampling will be delayed by 1 hour, but the full 8 hours of sampling will be
completed. (In this case, sampling will finish 9 hours after it started.)
If a power outage has occurred, “AC” will be
displayed in the error item field as in the figure,
in the main screen during operation. In addition,
operation will continue as per the remaining
operating time shown.
It is not possible to confirm exactly when the
power outage occurred or how long it lasted
during operation.
After operations have ended, check the details of
the power outage using the sampling data or last
data. (See pages 30 and 32.)
Relationship Between Error Display and Power Outages During Timer Operation
When a power outage occurred during the timer operation, the process is changed as follows
according to the situation at that time.
During standby
········ “AC” is displayed, but when the blower runs, the error disappears.
Clock timer used
After the power is restored, if the operation start time has been exceeded, the blower will
start running immediately.
Delay timer used
The time is counted even during the power outage. For example, if there are 30 minutes
remaining, and a power outage occurs for 10 minutes, after power is restored, the sampler
will standby for the remaining 20 minutes.
During operation
······ “AC” is displayed, and a power outage is registered.
(See pages 30 and 32.)
After operations have ended
······ “AC” is displayed but a power outage is not registered.
