Instrument Security Procedures
Model:
Fluke 1760

Product Name:
Fluke 1760 Power Quality Recorder

Instrument Description:
Three-Phase Power Quality Recorder Topas

Memory Description:
The 1760 Power Quality Recorder has numerous internal non-volatile memory devices
for holding instrument firmware and data:
• An internal Compact Flash memory card stores LINUX operating system, log files,
application firmware, FPGA configuration, calibration constants, measurement setup
data and application data files.
• An FPGA with on-chip flash memory for holding the configuration (optionally, if
transient analysis is built in).
• A small EEPROM in each sensor stores the serial number, type of accessory and
calibration constants.
• Industrial CPU board containing CPU boot firmware and memory for storing BIOS
settings

Memory Cleaning Instructions:
1. Connect to the Fluke 1760 Power Quality Recorder using PQ_Analyze.
2. Use “Advanced Settings” in PQ_Analyze to delete measurement data stored in the
internal Compact Flash card.
3. Reset network settings to default.
Note
The Ethernet network configuration will be set to DHCP enabled.
After accomplishing this instruction it is not possible to connect
to the instrument in a LAN where fixed IP addresses are used. A
peer-to-peer connection using the cross-over cable and a USB
connection is still possible.
4. Rename device to its default name.
For more information, detailed step-by-step procedures can be found on the following
pages.

Memory Cleaning Limitations:
The LINUX operating system, application firmware, FPGA configuration in the internal
Compact Flash memory card are factory programmed or updated during a firmware
update, 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 instrument serial number and calibration constants that are stored on Compact
Flash memory card cannot be modified by the user and cannot be cleaned.
The Fluke 1760 Power Quality Recorder does not provide secure erasure of
memories/files. Consequently, it may be possible to recover data from the 1760 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.

Detailed Memory Cleaning Instruction
1. Use the USB cable to establish a connection to the PC. Alternatively a connection to
your LAN or a peer-to-peer LAN connection using the cross-over cable is also
possible.
2. Turn on the instrument.
3. Start software PQ_Analyze.
4. Connect to the instrument:
