  • Page 16: Operation

    CHAPTER 4 OPERATION Operating Modes The Sentinel Logger has three modes: RECORD, STANDBY and OFF. ™ After the instrument has been turned on, the operating mode of the logger can be determined by pressing the PRESS button for less than 1.5 seconds. The GREEN LED indicates the mode of operation: LED OFF: Logger is turned off LED Single Blink: Logger is in Standby Mode (and not recording)
  • Page 17 Operations are determined by the length of time the control button is pressed. The lighting of each LED in sequence provides a visual indication that a required amount of time (for each operation) has been reached. The following table illustrates the operations that can be performed while in each of the three modes.
  • Page 18: Connecting The Sentinel™ To Your Computer

    Connecting the Sentinel to your Computer ™ DO NOT CONNECT THE SENTINEL TO THE COMPUTER UNTIL THE SOFTWARE & DRIVERS HAVE BEEN INSTALLED. Figure 4-1 shows a typical hook-up. The Sentinel Data Logger utilizes an ™ optically isolated USB communication port. The manual for your computer should indicate where to find the USB port.
  • Page 19: Recording Data

    There are two thresholds for the battery voltage depending on how the instrument is turned ON (either button press or DataView ) and the record- ® ing state that it is in. • If the unit is turned ON from a button press, the threshold is 4.3V.
  • Page 20: Downloading Recorded Data

    To Stop Recording: 1. Push the PRESS button for >3s and <5s. The RED and GREEN LED will turn on simultaneously. 2. The GREEN LED will change from a double-blink to a single-blink, indicating STANDBY mode. The data will be retained, even if the instrument is turned OFF. The recorded data may be downloaded to a hard-disk.
