Understanding the Measurement Complete Signal

The trigger port on the Meter's back panel provides a low-true pulse at the completion of
each Meter measurement. See the specifications section for more details on this signal.

Accessing and Controlling Memory

The Meter stores readings and meter configuration information using internal and
external memory (8846A only). On the 8846A, external memory connects through the
USB port on the front panel of the Meter. Optional Memory in various storage capacities
is available from Fluke. See the "Options and Accessories" section in Chapter 1 for Fluke
part numbers. In addition to storing and recalling readings and configurations, a memory
management function is available to delete files.
To access the Memory functions, press the M key. The memory menu appears over
the five soft keys: RECALL CONFIG, RECALL READING, STORE CONFIG,
STORE READINGS, and MANAGE MEMORY.

Storing Readings in Memory

The Meter will hold up to 9999 readings in one internal memory file. The 8846A, with
external memory, will hold 999 additional readings files, each of which will store up to
10000 readings.
