1-12 Secure Environment Workplace
This section describes the types of memory in the Site Master, how to delete
stored user files that are in the internal memory, and recommended usage in
a secure environment workplace.
Site Master Memory Types
The instrument contains non-volatile disk-on-a-chip memory, EEPROM, and
volatile DRAM memory. The instrument does not have a hard disk drive or
any other type of volatile storage memory.
EEPROM
This memory stores the model number, serial number, and calibration data
for the instrument. Also stored here are the user-set operating parameters
such as frequency range. During the master reset process, all operating
parameters that are stored in the EEPROM are set to standard factory
default values.
RAM Memory
This is volatile memory used to store parameters needed for the normal
operation of the instrument along with current measurements. This memory
is reset whenever the instrument is power cycled. Standby mode does not
reset this memory.
External USB Flash Drive (not included with the instrument)
This memory can be selected as the destination for saved files. You can also
copy the contents of the internal memory to the external flash memory for
storage or data transfer. The external USB flash drive can be reformatted or
sanitized using software on a PC.
Refer to Chapter 10, “File Management” for additional information on saving
and copying files to the USB flash drive.
Note
The screen images on your instrument or computer may vary
from what is shown in this User Guide.
