User's Manual

Memory Cleaning Instructions:
1. Connect to the 1750 Power Recorder using either Fluke Power Analyze
(FPA) running on a compatible PC connected via Ethernet or Fluke Power
View (FPV) running on the supplied PDA connected wireless via Bluetooth. If
the 1750 is password protected, the user must know and enter the password
before proceeding.
Note
For more information, detailed step-by-step procedures
start on page 3.
2. Use the “Erase 1750 memory” feature of either FPA or FPV to clean
application data-capture files and user-inserted annotation files stored in the
internal Compact Flash memory card.
3. Use the “1750 SD Memory” feature of FPV to clean files from the Secure
Digital card if the SD card is present in the 1750 Power Recorder SD card
socket.
4. Use the “1750 Setup” feature of either FPA or FPV to clean user-accessible
recorder configuration data such as recorder date and time, recorder name,
recorder password, and recorder Ethernet network address by setting data
fields to 0 or blank as appropriate.
Note
Cleaning the Ethernet network address will render the
Ethernet interface unusable and cause the Ethernet
connection to be lost. Be sure to complete the previous
steps first.
5. Remove external AC power continuously for at least six minutes. The internal
UPS will power down after five minutes at which time the application
firmware, FPGA configuration, and working data will be lost from volatile
memory.
Memory Cleaning Limitations:
CPU boot firmware and Bluetooth radio embedded processor firmware in
dedicated flash memories, CPU and DSP application firmware, FPGA
configuration, and flash memory and configuration backups in the internal
Compact Flash memory card are factory programmed or updated with Fluke field
service authorized upgrades, contain no user data, are not unique to the
instrument, and cannot be cleaned.
The internal Compact Flash memory card contains application log files that
cannot be cleaned. They save a limited rolling history of status and diagnostic
information for the instrument for use by service personnel.
The calibration constants, recorder serial number, Ethernet MAC address, and
Bluetooth Device address that are stored in the small EEPROM cannot be
modified by the user and cannot be cleaned.
The 1750 Power Recorder does not provide secure erasure of memories/files.
Consequently, it may be possible to recover data from the 1750 even after these
memory cleaning instructions have been followed. In addition, some files that
cannot be cleaned by this procedure, such as application log files, may contain
Ethernet network addresses and other information that could conceivably be
used to identify specific instruments, when and where they recorded data, and
other potentially sensitive information.
