Note: You may see this message when configuring data logging: Sample interval is limited by meas-
urement settings . The measurement time is determined by the measurement function, NPLC, Aperture,
Autorange, Autozero, Offset Compensation, AC Filter, TC Open Check, and Gate Time. The data logging
Sample Interval cannot be less than the measurement time. You can shorten the measurement time by
selecting less integration time, selecting a fixed range, and so on.
Step 4: Press the Duration softkey to specify the length of time to log data, or, press Duration again to
specify the total number of readings to log.
Step 5: Press Start to specify when to start data logging. You can select:
Start Delay - Starts data logging after a specified time delay. Specified in HH.MM.SS format.
l
Start Time of Day - Starts data logging at a specified time of day. Specified in HH.MM.SS format.
l
Using the time of day requires that the instrument's real-time clock is properly set. To set the clock,
press [Shift] > [Utility] > System Setup > Date/Time .
You cannot configure a trigger source when data logging. You can only use auto trigger (selec-
ted by default) or, when ready to initiate data logging, you can cause a single trigger (by pressing
[Single] ). The effect is the same, as you only need one auto trigger or single trigger event to enable data
logging.
Step 6: Press Log To > Log To Memory or Log To Files to specify whether the data logging results will be
stored in volatile memory for display or written to one or more internal/external files.
When data logging to memory, the data is volatile (not remaining during power off) but can be saved
l
to an internal or external file after data logging is complete (see Step 7 below). The number of readings
you can store in memory depends on the amount of instrument memory. With the MEM option, the
limit is 2,000,000 readings. Without the MEM option, the limit is 50,000 readings.
