2 Features and Functions
Data Logging
The Data Logger feature (34410A/11A only) provides a front–panel user interface that
allows you to set up data logging into the instrument’s non–volatile memory without
programming, and without a connection to a computer. Once you have finished
collecting data, you can view it from the front panel, or you can then connect your
computer and import the data.
The 34410A/11A Web Interface provides a very convenient way of importing the data
into your spreadsheet or other application.
The 34410A/11A allows you to set the following data logging parameters:
START DELAY, INTERVAL, EVENTS/TIME (COUNT or DURATION).
• START DELAY is the delay time (0 to 3600 seconds) after initiating a trigger, before
the data logging function takes its first reading.
• INTERVAL is the time (20 μ
s to 3599.99999 s) between subsequent readings. The
minimum interval is configuration dependent and may be greater than 20 μs.
• EVENTS/TIME is the total duration of the data logging session. You can set a
COUNT of total readings, with N SAMPLES settable from 1 to 50,000 readings. Or,
you can set a DURATION in hours, minutes and seconds. The maximum duration
that you can set is limited to that which results in 50,000 readings, but in no event
more than HH:MM:SS = 99:59:59 (just under 100 hours).
• Front Panel Operation: To set up a data logging session, press
DATA LOGGER > SETUP > START DELAY > INTERVAL > EVENTS/TIME
• For START DELAY, enter the desired delay (use the navigation keypad).
• For INTERVAL, enter the desired interval.
• For EVENTS/TIME, select either COUNT or DURATION. Select COUNT if you
want to enter a total sample count. Select DURATION if you want to enter a time
duration.
• Upon pressing , the message TO START - PRESS TRIGGER KEY appears.
The data logger is now ready to go. Just press to begin logging. (A trigger
pulse on the Ext Trig connector will also initiate the session.)
• After the specified delay, the main display will show the data as it is collected,
while the second display line shows a progress bar and the current count (down).
The Data Logger logs data to non-volatile memory. Once the Data Logger has saved the
data, you can turn off the power, move the multimeter, and then view or retrieve the
logged data after turning the power back on. The 34410A and 34411A have non-volatile
memory for up to 50,000 readings, which is the limit for the Data Logger feature.
