With the DIG option, level triggering, pretriggering, and sample timer capabilities are enabled when using
the DMM from remote. From the front panel, level trigger is available for digitizing and for certain meas-
urement functions in continuous mode (see
for more information). Pretrigger front panel
controls are only available in the digitize mode. The sample timer controls are available from the front
panel for all measurement modes.
l
For pretrigger, if a trigger comes before all pretriggers are received, trigger is executed to begin readings.

display.

All samples taken during digitizing are saved in volatile memory. After completing a digitize operation,
press the
Save Readings
softkey and specify a file to save the digitized readings to a file.
l
The maximum number of readings that can be captured is based on volatile memory space available.

Reading store is cleared at the start of a new acquisition.

The slowest sample rate for digitizing is 20 ms (1 PLC); the fastest is 19.953 µs/50.118 kHz (.001 PLC).
l
Any display mode can be set to view data during acquisition but responsiveness to data views may not
respond until data acquisition is complete. After acquisition is complete – trend chart pan, zoom, and curs-
ors can be used to review data.
l
Statistics and histogram data are calculated after the digitizing is completed.
