FS-5T

APPLICATION: The FS-5T Automatic Scaler is a line operated instrument with battery standby. Uses include sample or wipe counter. ``Frisker'' monitor and lab monitor. It includes a digital ratemeter operating mode in which it presents 7 full decades of accurate readout without switching. The FS-5T is also used as an area monitor, again making use of the digital ratemeter modes covering seven decades and also utilizing the preset alarm that is built into the instrument. An extra safety feature of the FS-5T when it is used as an area monitor is that a switch is automatically made to battery operation in event of power failure.

DESCRIPTION: The FS-5T is a multi-purpose lightweight Scaler with internal chargeable battery. All GM and scintillation probes are usable with the FS-5T as are digital ion chamber and gas proportional probes. The FS-5T is a sturdy table top or portable instrument incorporating both scaler and ratemeter functions, three independent single channel analyzers, switch selectable and variable high voltage 0-2500V. The panel meter is a taut band type for maximum ruggedness.

Pulses are seen via a red LED for visual service in dark areas and the time base for the scaler operation is indicated by a flashing green LED. High voltage is settable to accommodate for all types of scintillator, proportional and GM detectors. Four ranges are incorporated into the ratemeter. Gate times for the scaler may be set from 1 to 99 seconds and 1 to 99 minutes. The scaler has an auto cycle capability particularly useful for increasing the accuracy of rate measurements. Power switch and HV pot and other controls are designed to prevent inadvertent change. The output of the ``beeper'' is varied by a volume control from completely silent to loud enough to be used in noisy environments. Standard features include output jack for optional chart recorder. Readings directly in mR/hr or other units can be made by choosing correct recycling time on the scaler or with transparent meter overly card on the ratemeter.

Optional digital printer, strip chart recorder and RS-232. IEEE 488 and other interfaces make FS-5T fully system compatible.
