To conserve battery life, do not leave the TH10 connected to the USB port for a prolonged period of time 3 TH10 V1.0 9/07 MENU BAR DESCRIPTION The main menu for the software appears as follows: From left to right the MENU BAR icons represent DATA DOWNLOAD, LOGGER SETUP, FILE OPEN, FILE SAVE-AS, FILE PRINT, VIEW ALL, and ZOOM. In addition, the FILE, VIEW, LINK, and HELP pull-down menus are available here. All of these functions are described in the following paragraphs. LOGGER SETUP Click on the computer icon on the menu bar (2nd from left) or select LOGGER SET from the LINK pull-down menu. The Setup window will appear as shown below; descriptions for each field in the Setup window are listed directly below the illustration: The CURRENT TIME field will automatically synchronize with the PC date and time setting. The MANUAL and INSTANT select buttons allow the user to start data logging immediately when the Setup window is exited (INSTANT), or at a later time (MANUAL). The LOGGER NAME field allows the user to select a unique name for the TH10. The SAMPLE POINTS field instructs the TH10 to take a fixed number of readings. The SAMPLE RATE pull-down menu instructs the TH10 to log readings at a specific rate. The LED Flash Cycle can be set by the user: longer cycle times help to extend the battery life. The ALARM SETTINGS area of the SETUP window allows the user to set high and low temperature limits and disable the flashing of the TH10’s LEDs, thereby conserving battery energy. Once the changes have been made, click on the SETUP button to save them. Press the DEFAULT button to set the TH10 back to factory default conditions. Press the CANCEL button to abort the setup. 4 TH10 V1.0 9/07 Note: Any stored data will be permanently erased when the user clicks on Setup. To save the data before creating a new setup, click Cancel and then download the data. Note: The battery may run out before the TH10 has finished collecting a specified number of sample points. Always ensure that the remaining charge in the battery is sufficient to last the complete duration of your logging exercise. When in doubt, we recommend that you always install a fresh battery before logging critical data. If INSTANT was selected in the SETUP window, the TH10 begins logging at the instant the SETUP button is pressed. If MANUAL was selected, the TH10 must be manually started by pressing and holding the device’s yellow button for approx. 3 seconds, or until the two LEDs on the TH10 flash at the same time. Logging will continue at the programmed sample rate until the number of readings (sample points) specified in the Setup window is reached. The green LED flashes once per sample point and the red or yellow LED flashes when user programmed alarm limits are exceeded. For details, see LED status guide. DATA DOWNLOAD To transfer the readings stored in the TH10 to the PC: A. Connect the TH10 to the same USB port used when the TH10 was initialized. B.
