The 451 Assistant for Excel is an Excel Add-in, a program that adds optional commands and features to Microsoft® Excel. The 451 Assistant provides remote control for many of the 451 functions, real-time data logging with user defined alarm parameters and a real time virtual
instrument display. The 451 Assistant automatically loads with Excel once it is installed.

The 451 Assistant data logging function automatically records real time measured data in an active Excel worksheet. Each measurement in the data log is automatically placed in the active worksheet cell, then the active cell moves down to the next row of cells where it will place the next set of measured data. Each recorded measurement is time and date stamped.

The 451 Assistant provides user configurable audible and visual alarms for the real time logged data. The picture and data shows radiation levels above the preset alarm in red, the blue data
represents the radiation level below the alarm that has not been acknowledged. The black data shows when the alarm was acknowledged. See Control Options for more details.

The 451 Assistant for Excel allows the user to configure the 451’s internal data logging and alarm settings. It may also be used to download the 451’s internal data log and saves it in an Excel worksheet where it can be easily graphed for quick trend analysis.

The 451 Assistant provides automatic timed integrated dose measurement over a user defined integration period or user controlled integrated dose measurement. After the integration timer has expired or the user has stopped integration, the 451 Assistant retrieves the integrated dose from the 451 and inserts the integrated dose in the active worksheet cell and the average dose rate is placed in the next cell to the right.

The Model 451EXL information management software program is ideal for the facility Radiation Safety Officer or anyone responsible for maintaining a permanent record of spills and accidents for adherence to state and NRC requirements. The remote control of the 451 series of Ion Chambers may be accessed by any computer on your facility network providing remote inform-ation management.

Controls The 451 Assistant menu and toolbar provide an interface for the user to remotely control the 451, configure the 451, ownload the 451’s internal data log and start / stop real time data logging and integrated dose measurements.

Connect / Disconnect Connects or disconnects the 451 to the computer’s communication port.

Start / Stop Starts and stops computer data logging. When data logging is started, logged data is placed in the active Excel worksheet and the worksheet is protected to provide data security.

Logging Properties Allows the user specify computer data logging parameters. The data logging sample interval (2 seconds to 999 hours), total data logging period (2 seconds to 49 days) and computer data log alarms may be specified through this menu. These parameters are independent of the 451’s internal data logging functions.

Integrate Allows the user to select timed integrated dose measurement or user controlled integrated dose measurement. The user may also specify the integration period for timed integration from 1 minute to 999 hours. When timed integrate mode is selected, the 451 Assistant for Excel stops the integrated dose measurement after
the specified integration period has expired. When timed integrate mode is not selected, the user controls the integration period and the integration time is displayed in real time. The integrated dose and average dose rate are recorded in the active Excel worksheet when integration is complete.

Download Log The 451 is capable of internally logging data at a user defined interval from 1 to 255 seconds with a total capacity of up to 2700 data points. This feature allows the user to download the 451’s internal data log into the active Excel worksheet

The four alarm states are acknowledged normal (below alarm level), unacknow-ledged normal, acknowledged alarm and unacknowledged alarm. The user may also select the communication port used by the 451 (default is COM1). The 451’s internal data logging parameters and alarm settings may also be changed from the Options menu.
