To configure the instrument to append or overwrite measurements the next time data is acquired:
1. Press
the
CONFIG
key. Select
STORE
, and then select
STORAGE-MODE
. The Storage Mode
menu is shown.

•
APPEND
•

3. Press
the
EXIT (LOCAL)
key to return to the main menu.
Storage operation
Use this option to initiate a storage operation and to configure the number of readings to acquire
during the storage operation. The reading count can range from 1 to 60,000 with timestamps and
source values enabled; the count can range to over 140,000 with timestamps and source values
disabled.
To store the maximum number of readings in a reading buffer (over 140,000), disable the source
values and timestamps for that reading buffer.
To specify the number of readings and initiate the storing operation:
1. From the front panel, press the
STORE
key, and then select
TAKE_READINGS
.
2. Use the navigation wheel
to select the number of readings.
3. Push the navigation wheel
to switch to edit mode.
4. Turn the navigation wheel
to change the numeric value, and then push the
navigation wheel
to save the numeric value.
5. Press
the
ENTER
key to save the count.
6. Press
the
OUTPUT ON/OFF
control to start taking readings.
If the output-off mode is ZERO or the output is already on, the instrument starts acquiring readings
when the ENTER key is pressed (see step 5 of the preceding procedure). Otherwise the instrument
starts acquiring readings when the output is turned on (step 6).
Saving reading buffers
You can save the dedicated reading buffers to nonvolatile memory, or you can save them to a USB
flash drive. Note that the instrument will restore the dedicated reading buffers from internal nonvolatile
memory when the unit is turned off and back on.
Saving the reading buffers to nonvolatile memory
After the measurements are complete, you can save the reading buffer data to the nonvolatile
memory in the instrument.
