Wavelength Selection
Set the Wavelength Selection to the correct laser setting by
1. Pressing Pause to stop display of measurements.
2. Pressing the wavelength selector button to enter wavelength setting dialog.

a. For sensors with discrete wavelength selection this will open a list with
all available wavelengths. Select the desired wavelength
b. For sensors with continuous wavelength selection, this will display a
slider & text box open showing current wavelength. Modify wavelength
with slider or type in new value and press “OK”
3. Pressing Play to start display of measurements.
Filter Setting
For photodiode sensors equipped with an optional filter, change the filter setting by
1. Pressing Pause to stop display of measurements.
2. Clicking the toggle button that appears next to the label “Filter is”. This may take
a few seconds to take affect after which the new state is displayed.

3. Pressing Play to start display of measurements.
Note: Make sure to physically insert or remove the filter, according to the
filter setting selected. Failure to do so will result in erroneous
readings.

Chapter 4 –Error Screens & Recovery Configuring the Measurement Parameters
Quasar Reader User Guide Page 10
Chapter 4 –Error Screens & Recovery
Error Screen
Explanation and How to Recover
Connection failed because Quasar is powered down, out of
range, or with an unsupported sensor type (ex. Pyro)
To recover try one of the following
Turn Quasar device on
Move closer to quasar
Turn quasar off, replace sensor, turn quasar on
Connection was lost
To recover enter the pairing code, as requested, and
continue
No sensor connected to Quasar
To recover connect a sensor to the Quasar and try again
Display is stuck showing 0000
This happens when the power reading is out of the sensor’s
range of measurement. There is nothing to do. When the
power comes within range, the measurement update will
resume.

Chapter 4 –Error Screens & Recovery What to do when the reset doesn't work
Quasar Reader User Guide Page 11
Select Quasar dialog box is empty
This happens when no Quasar has been paired with the
smart phone. Quit the application and perform the pairing
sequence described above and try again
How to reset the app if it gets stuck
After replacing a sensor on the Quasar device, you must turn the Quasar off / on.
If the application is stuck; to quit, press the menu key to open select/quit screen.
oIf that does not help, enter the Task manager to end the application.
If the application does not response as expected (i.e. stuck, no readings), follow
the recovery scheme below.
Progress dialogs in the application have a “Cancel” button.
This button is intended to free the app if it gets stuck (taking too long).
However, since cancelling in the middle of command sequence can leave the
application in undetermined situations, therefor, after canceling, it is
recommended to execute the recovery scheme below.
Recovery scheme: Follow the sequence below:
1. Exit Quasar Reader application - preferably using the application quit menu
2. Make sure Quasar Reader application is not active
3. Turn your quasar "off"
4. In bluetooth settings:
i. Unpair quasar
ii.Disable (turn "off') Bluetooth
5. Turn your quasar "on"
6. In bluetooth settings:
i. Enable (turn "on) Bluetooth
ii.pair quasar
What to do when the reset doesn't work
Quasar Reader trouble shooting sequence:
Unpair Quasar device from phone's Bluetooth
Turn Quasar device off
Turn phone Bluetooth off
Turn phone off
Turn phone on
Stop all applications on phone
1. Run quasar reader application
2. [while keeping the quasar reader app running] Turn Bluetooth on
3. Turn Quasar device on
4. Pair phone Bluetooth with Quasar device
5. Return to quasar reader application
6. Select device etc.
