Introduction
About Your Model 700e Series Unit
The Ludlum Model 700e series includes the Model 702e, 703e and 711e. They are portable
radioisotope identification (RID) systems that detect and identify multiple nuclides, providing
quantified results using time-slice analysis.
The 700e series of instruments use an externally housed NaI detector. The external detector
eliminates the need for an embedded source to provide gain stabilization and self-calibration and
allows for meeting ANSI N42.34 standard.
The instruments can be operated either in a very simple mode requiring no previous experience or in
other operating modes that take advantage of the comprehensive set of advanced features.
The Model 700e units offer two log-on modes: User and Administrator. The User functions allow
first-line responders to perform all the tasks needed in the line of duty. The Administrator
functions allow a health physicist, or other expert, to set up the device for specific applications and
to perform additional maintenance functions. This manual will cover aspects of both, but places an
emphasis on User functions.
CAUTION! It is important to limit access to Administration Mode to those who are
qualified to use it. This mode includes the advanced functions of the instrument and
allows the user access to everything. The general user should be limited to User
Mode only. If any of the advanced functions are altered incorrectly, it could affect the
overall function of the instrument and may require expensive re-calibration. Please
see Section 2, starting with page 2-5, for details on how to set up the Administration
Mode and protect the mode with a password.
Once you set a password for the Administration Mode, it is important not only to
keep it private, but to not lose it or forget it. If the password is forgotten, it can only
be reset by the factory.
In addition, do not alter calibration settings, or it may incorrectly alter the
instrument’s functions and require repair by the factory.
After logging on, the device powers up in an initial search mode. Several different views of this
mode are available, but all are based on data collected in real time. In addition to the search modes,
setup, alarm review, and calibration functions can be accessed through the menu system.
The instrument has a simple user interface and a wide range of setup functions and utilities.

The Model 700e series unit can be connected to a remote computer using an Ethernet cable, and
accessed with either Quantum™ MCA (standard) or Quantum™ Gold (quantitative analysis)
software. The Quantum™ software allows:
Up to eight MCAs to be controlled at one time, with full spectrum data in real time.
Unit analysis in 256 QCC or linear, 512 QCC or linear, and 1024 linear modes.
Note that if you are using either instrument without a PC, operation is limited to 256 and 512 QCC,
including the saving of spectra. However, while under control of Quantum software, all ADC modes
(including 1024 linear) are available.
The basic Model 700e series unit consists of:
The spectrometer electronics
External gamma ray detector
An AC power adapter
Ethernet connectivity for remote operation
Compact flash card spectra storage
Optional devices include:
Quantum software
A car power adapter
