General Questions

The GPS needs to sync to three or more satellites in order to provide accurate global positioning coordinates. When the Labdisc is first used, the GPS is in a “cold start” mode and it might take it 20 to 30 minutes to sync. Once it has synced you’ll see three arcs above the small GPS antenna icon gps iconon the Labdisc LCD. After the GPS syncs for the first time it will remember the sync data of the specific satellites, even when the Labdisc is turned off. This assures a fast sync of up to one minute in all future recordings when the GPS is used.
Some of the Labdisc sensors can record data at a maximum sampling rate of 10/sec or 1/sec. Selecting one or more of these sensors for data recording will limit the sampling rate to the lowest rate allowed by the slowest sampled sensor. For a complete table of maximum sampling rates per sensor please refer to section 2.7 Built-in Sensors of the manual.
Sleep mode is enabled only when both GPS and Bluetooth modes are disabled. Please make sure that the Labdisc display doesn’t show either of the following icons: gps icon or bluetooth icon. If one or both icons appear on the display, use the configuration menu config icon to disable GPS and Bluetooth modes.
Flash Player is missing or corrupted, to fix it do the following:
  1. Uninstall Flash Player. From the Control Panel select “Uninstall a program” and uninstall all versions of “Adobe Flash Player”.
  2. Download and install the latest version of Flash Player from http://get.adobe.com/flashplayer/

The Information and Control bar is located in the bottom right corner of the GlobiLab screen. It indicates the connection status and memory of the Labdisc. memory icon Right clicking on the memory indicator will open a pop-up menu where users can choose to delete the last experiment from the Labdisc, or clear all the experiments from the Labdisc.

In the GenSci and Primo the ambient temperature sensor is located inside the Labdisc. This means that it takes about 20 minutes to stabilize. Thus, it is suitable for long recordings like day and night temperature changes. In the Enviro the ambient temperature is located in the humidity chamber protruding from the Labdisc – meaning it is fast responding and more accurate.

The ambient temperature sensor is ideal for measuring temperature over a long period of time, for example in measuring the changes in temperature over a 24 hours period. If you require a more immediate reading of the surrounding temperature, you should use the external temperature, thermocouple or infra red sensors; since the ambient temperature takes a little longer to read the “real” surrounding temperature.

This procedure allows users to update the code used by the internal micro-computer of the Labdisc. This code is referred to as the Labdisc firmware. New firmware releases include bug fixing and additional features. All Labdisc models: Enviro, Gensci, Biochem, Physio and Primo use the same firmware.
To update the Labdisc, please follow the steps below:
  1. Make sure that the Labdisc battery is charged, or connect the Labdisc to the charger
  2. With the USB cable connect the Labdisc to the computer
  3. Run the GlobiLab software
  4. Make sure the bottom right USB icon has turned blue bluetooth icon if it stays gray make a left mouse click on this USB icon
  5. From the GlobiLab toolbar click the Configuration iconconfiguration icon
  6. In the opened dialog box, click the second tab “Firmware update”
  7. Enter the password (default password = 1234) and press OK
  8. In the screen below click Open File and select the new firmware file “Firmware version x.xx. HEX”
  9. Press Burn configuration screen
  10. The Burning of the new firmware may take few minutes. During this time the Labdisc will start beeping and flashing its LCD display, while the green progress bar shows the percentage of code being flashed into the Labdisc micro-computer memory.

Make sure that you’ve attached the ear-clip correctly and you are at rest, as motion will effect readings. The ear-clip has an IR light source on one side of the clip and a light detector on the other side. Blood flowing through our body changes the skin IR transparency which is measured by this sensor. The ear-clip should be attached to the soft section of the ear-lobe (an earing hole may interrupt the operation of this sensor). You may also attach the sensor to the index finger or to the soft skin between the Index finger and the thumb.
 
When starting a measurement with the Labdisc, adjust the sensitivity of the ear-clip sensor to suit. If in the first five seconds of the measurement no clear pulses are observed, the Labdisc will increase the IR emitted intensity and look for pulses for a further five seconds. If not clear pulses are measured the Labdisc will increase again the intensity of the IR to maximum intensity. At this stage no pulse means that the sensor is not well attached to the ear, or the ear-clip detector is exposed to ambient light. After a pulse is detected the Labdisc will count 16 pulses and then will start to display the heart rate in BPM. For each pulse the Labdisc will produce a short beeping sound.
Please follow the steps below:
  1. Place 100 ml DI water into a 150 mL beaker. Bubble air through the water while stirring for 20 minutes. This will saturate the water with air/oxygen and create a 100% DO calibration standard. To prevent air entrapment (from the bubbles) on the DO electrode membrane surface use an electrode holder that keeps the electrode at a 20° angle.
  2. To calibrate the reading for 100% saturated oxygen, press and hold the Labdisc DO2 key for 3 seconds until you hear a long beep sound. The data logger should show 8.25 mg/l which represents water saturated oxygen in room temperature of 25°C.
  3. If the water temperature is not 25°C, then use the Labdisc temperature sensor probe placed in the water near the DO electrode. Pressing and holding the data logger DO2 key will show the mg/l value correlated with the water’s actual temperature at 100% oxygen saturation.
The pH sensor is factory calibrated and under normal conditions does not require any calibration. Please follow the steps below should you wish to calibrate this sensor:
  1. Insert the Labdisc pH electrode into a 7.0pH buffer
  2. Wait for the Labdisc pH reading to stabilize
  3. Press and hold the pH key for 3 seconds, untill you hear a long beep sound
  4. The Labdisc pH sensor is calibrated and will show a reading between 6.95pH to 7.05pH
  5. pH calibration is not saved after the Labdisc is turned off
Please follow the steps below:
  1. Fill a clean cuvette with DI water
  2. Insert the cuvette to the Labdisc cuvette chamber
  3. Make sure the Labdisc displays one of the colorimeter reading (blue, red or green)
  4. Press and hold the colorimeter key for three seconds, until you hear a long beep sound
  5. The Labdisc Colorimeter sensor is calibrated but please note the colorimeter calibration is not saved after the Labdisc is turned off
