Instrument Security Procedures

Model:

729 / 729 FC

Product Name:

Automatic Pressure Controller

Instrument Description:

The Fluke 729 Automatic Pressure Controller is pressure/electrical

measurement/source instrument for process control. It measures

and records pressure, voltage, current, temperature, and other

readings from paired FC slaves.

Memory Description:

The Fluke 729 Automatic Pressure Controller has the following

memory on two Printed Circuit Assemblies:

Main PCA

- The 2M byte Flash Memory embedded in STM32F429 processor

is an electrically erasable and programmable memory that stores

instruction code for main microprocessor, the instruction code is

loaded at the factory or in Service and is not user accessible.

- The Synchronous Dynamic Random Access Memory (SDRAM)

provides 8M bytes of data storage for the instrument. This

includes operating memory for the microprocessor and temporary

storage of measurement data. The SDRAM is volatile memory

that clears when power is removed from the instrument.

- The 256k byte Flash Memory embedded in STM32F103

processor is an electrically erasable and programmable memory

that stores instruction code for EMM processor, and calibration

constants, the instruction code is loaded at the factory or in

Service and is not user accessible.

- The Ferroelectric Nonvolatile RAM (FRAM) provides 2k byte for

instrument setup, and is not user accessible.

- A Data Flash Memory provides 4M byte provides storage for

download/customer tasks, calibration results, and saved screens,

and can be cleared with the procedure below

- The 256k byte Flash Memory embedded in FTDI VNC2
