Page 18: Software Basics
RadPro International GmbH 6 Software Basics TLStudio is a powerful software that works with TLDcube (TLD-reader). The software contains the complete workflow beginning with the creation of heat ramps, measure count curves and up to high level dose evaluation. 6.1 Program Start up The program can be started by clicking the desktop icon. -
Page 19: Initial Setup
RadPro International GmbH 6.2 Initial setup To initially setup the program the following basic settings are mandatory: 6.2.1 Device connection setup TLStudio communicates with the device over a TCP/IP network connection. The following settings must be taken in the section “Devices” on tab “Main Control”: 1.) Log in with engineer login (user: Engineer, password: engineer) 2.) Right click in “Devices”... -
Page 20: Login/Logout
RadPro International GmbH 1.) Type in a profile name 2.) Create a heat ramp in the middle. 3.) Click “save” to store the recipe on hard disc. 6.3 Login/Logout Some TLStudio functions are only accessible via special login. Possible login roles are operator (this is the standard role) and engineer. The operator login is limited to select recipes/sets and start and analyze measurements. -

Page 23: Detector Temperature
RadPro International GmbH 7.2 Detector temperature In the device details, the current Photosensor temperature is shown. The background of this field is colored depending on the difference to the setpoint. The reader is shipped with a setpoint of 25 °C, but this point is adjustable. It should not be changed after calibration. Green means the detector temperature is in a good range. -
Page 24: Measure Sets With Predefined Elements
RadPro International GmbH The measurement results (data curves) will be displayed in the analysis section of the software. 7.3.2 Measure sets with predefined elements In this mode a predefined set with elements will be measured. Therefore the Set must be created with the built in Set editor in the controlling area. -
Page 25: Measure Elements Based On Existing Set-Calibration
RadPro International GmbH The measurement results (data curves) will be displayed in the analysis section of the software. 7.3.3 Measure Elements based on existing Set-Calibration With this mode, it is possible to use an existing Set and calibration to measure and evaluate Elements outside this Set. -
Page 26: Measuring The Dark Counts
RadPro International GmbH The currently performed step is announced by the “Run state” element in the “main control” tab. In addition to this visualization, the state of the device is displayed by a lamp on the “open button” on the device itself. In idle mode the lamp will glow constant whereas a slow pulsing lamp is indicating a running measurement. -
Page 27: Measuring The Actual Luminescence Signal
RadPro International GmbH The Gas state indicator shows if the pressure at the inlet is sufficient. It is possible that the pressure falls below the threshold during the chamber fill process, but that is not a Problem. 7.4.4 Measuring the actual luminescence signal In the actual measurement, the device will execute the assigned heating profile. -
