Model 90100

Operators Manual

cable is of a design that provides a high degree of flexibility and allows it to flatten to fit under a treatment room entrance door.

Included with each 90100 TRACKER System is an MS-DOS based Customization program that provides a means of performing field customization and calibrations. Some of the items that may be field customized include the measurement display units, temperature and pressure units, the ion chamber calibration factors, and the number of minutes to power down. This program may also be used to generate a printed report containing all of the customization and calibration settings.

A number of optional accessories including a carrying case for storage and transport, build-up plates of various thickness/materials, and a build-up retaining hardware kit are available also.

1.2 Features

•Measurement values from peripheral ion chambers may be displayed in either absolute dose measurement units or as a percentage of the center ion chamber's measurement value.

•A wide AC Line Input Range of 100 to 240 VAC and the use of an IEC 320/C13 style receptacle provide worldwide operation by use of the proper line cord.

•The levels of the internal 300 V electronic bias supply and the rechargeable battery supply are continuously monitored. Annunciators appear on the display if an abnormal bias voltage or low battery voltage level is detected.

•All front panel settings are automatically stored at power down and restored at power up eliminating the need to reconfigure the front panel settings upon each use.

•Dose measurement values may be displayed in units of roentgens, rads, sieverts, grays, or monitor units. Dose rate measurement values may be displayed in units of roentgens/min, rads/min, sieverts/min, grays/min, or monitor units/min.

•Front panel gain settings allow the user to easily match displayed measurement values to the linear accelerator's monitor readout or to a precision calibration.

•Precision five-channel electrometer provides ± 0.003% linearity and a long-term stability of better than 0.25% of reading per year.

•The system may be operated from either AC line power source or from its internal battery. The batteries will be charged during use from AC line power.

•A high performance rechargeable battery system provides 8 hours of continuous operation from a 3-hour charge. A low battery annunciator indicates when 30 minutes or less of operation remains.
