  • Page 7: General Information

    Grant Instruments General information The yoyolog series consists of a large variety of loggers: Some have an internal sensor only. Others have inputs for external sensors, whilst some have both sensor types. A full list of models can be found on our website.

  • Page 8: Installing The Batteries

    Grant Instruments Installing the batteries The logger’s power supply is provided by a 3.0V lithium battery (CR2477N). Optionally for high-temp-applications a CR2450HT battery can be supplied. The device offers internal battery monitoring. YoyoView will indicate when the battery will require replacing. In addition, the LED flashing periodically indicates the need for the battery to be replaced (see chapter 0, understanding LEDs for further information).

  • Page 16 Grant Instruments In the Start Datalogger window, the Stop condition for the logger can be set. If the Memory full option is selected the loggers will stop logging when the memory is full. If never (cont mode) option is selected the logger will start to overwrite the oldest readings when the memory is full.

  • Page 17: Download Data

    Grant Instruments Download Data Clicking on Download Data will transfer all stored data to your PC. It will automatically store the files as a *.BIN-File and as a*.ASCII file. The original *.BIN-File is a compressed datafile which can be archived using a minimum of hard disk space.

    Grant Instruments Logger Setup - General Click on Logger Setup, to define general settings for the logger, i.e. channel settings, alarm settings). A picture of the logger is displayed so the inputs/slots can be identified. The battery capacity is displayed in the same picture. If the battery status is “green”...

  • Page 19: Logger Setup - Sensor Slots

    Grant Instruments Logger Setup – Sensor Slots Those loggers that have additional inputs for external signals or sensors have to be configured correctly to show the expected values and prevent damage. The input types that can be configured for different sensor/signals types are shown in the table: 30641 V1.3...
  • Page 20 Grant Instruments Click on Logger Setup, to configure the inputs. The actual configuration of the logger and the range are displayed. Click on the Sensor Slots tab. NOTE: This function is only available when the logger is not logging. Click on the symbol of the slot to be modified for example Slot2.
  • Page 21 Grant Instruments YoYoView automatically assigns the minimum and maximum values of the sensor range. This can be altered if required. In order to set engineering units for the sensor, select Change to new Unit in the section SensorRange. Further settings can be entered. The above example shows the values for a sensor with a linear range of 0…50m/s = to 0…1V.
