1-5 Secure Environment Workplace General Information
The Site Master is self-calibrating and there are no field-adjustable
components. The OSL calibration components and the Internal
InstaCal are crucial to the integrity of the user calibration. As a result,
they must be verified periodically to ensure performance conformity.
This is especially important if the OSL calibration components have
been accidentally dropped or over-torqued.
1-5 Secure Environment Workplace
This section describes the types of memory in the Site Master, how to
delete stored user files in 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. The user 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 8, “File Management” for additional information on
saving and copying files to the USB flash drive.
