• Time-activated job: The Logger starts logging as soon as the
preprogrammed start time is reached, and stops at the defined end
time.
• Immediate job: The Logger starts logging as soon as power is on.
Note the following about logging jobs:
• The connection can be verified using the logging channel LEDs. If all
three LEDs are lit continuously, the connection and the signal levels
are within nominal range. For details, see Table 4 in the Features
section.
• The unit/job status is indicated by the status LED. For details, see
Table 4 in the Features section.
Completing the Logging Job
1. Terminate the job as follows:
• For switch-activated jobs: At the end of the logging period, stop
the logging job by pressing the START/STOP button.
• For time-activated and immediate jobs: Stop the job in PQ Log
with the icon, or with menu Logger/Stop logging.
Note
Make sure the logging job is stopped with the START/STOP button
(switch-activated jobs) or PQ Log (time-activated jobs) before the test
leads or power supply leads are removed. Otherwise, the Logger will
record a voltage interruption.
Only switch-activated jobs can be aborted. Time-activated jobs are
terminated only when the programmed measuring time has elapsed.
2. Remove the test leads of the three phases. Be sure to remove the
measuring cable of the neutral wire last.
3. Remove the current probes.
