New Firmware, Improved Compass Routine

MultispeQ Firmware v2.0038 has a new and improved compass routine, that can more reliably read compass direction when the device is tilted. Once the instrument is updated, you must calibrate the compass to enable it to work.

More information is given in the announcements section of the forum.

Please follow these steps:

1) Connect to the desktop app, and access the console.

2) Enter the command calibrate_magnetometer

3) Rotate the device in ALL directions. Make sure the nose of the instrument draws out a “sphere” in the air. Also, ensure the instrument is rolled in all directions while calibrating (Like a plane does a barrel roll). All movements should be slow and arc-like.

4) After calibrating the magnetometer, find the protocol “compass and tilt only”.

5) Point the MultispeQ towards a cardinal direction, and select “run”. Ensure that the measurement “Compass_direction” shows the direction the device was pointed. Repeat for all cardinal directions.

6) Put the MultispeQ on a level surface and run the protocol again. The measurements “Angle”, “Pitch”, and “Roll” should all be close to 0 or 1. If not, please recalibrate the instrument, taking extra care to rotate the device in all directions.

7) Tilt the instrument on its side. Run the protocol, and make sure “Roll” shows a value of around +/-90.

8) Turn the instrument upside-down. Run the protocol, and ensure the value for “Roll” is close to +/-180.

9) Next, tilt the instrument’s nose upwards at an angle. The value “Pitch” should reflect the angle the MultispeQ is tilted. If the device passes these tests, the magnetometer was calibrated successfully.

After updating, if your device is having trouble taking measurements or is acting slow, calibrate the open and closed positions. To do so, access the console on the desktop app and type in set_open_closed_positions. Open the device’s clamp 2mm~, and enter “+” into the console. Then, open the clamp to 4mm~, and enter “+” into the console.

New Firmware, New MultispeQ, Updated Apps

The PhotosynQ team has been working hard to bring you a new, updated platform! Starting now, and continuing over the next few weeks, we will be releasing new versions of the MultispeQ, firmware (with new associated programming tools), and desktop App.

MultispeQ Version 2.0. Many users are already receiving the new V2.0 device, which has a lot of updated capabilities. Some of these are obvious (like the nice blinking lights that tell you what the instrument is doing. and others. like compatibility with stomatal new conductance measurements, will be rolled out in the coming weeks.

MultispeQ Firmware Version 2.0 for both V1 and V2 devices. This is a major upgrade with lots of new features and improvements. Although the new version is almost completely backwards compatible, it allows much greater flexibility and powerful programming. We will be introducing the new capabilities in installments over the coming weeks.

PhotosynQ Desktop App. We are releasing a new version of the Desktop App which will replace the current one for the Google Chrome Browser (Chrome App). One  reason is that support will be ended for Chrome Apps on Windows and MacOS. Other important reasons for the update are to accommodate new capabilities of Firmware 2.0 and higher, and give you more powerful analytics and visualization tools.

PhotosynQ Android App To make use of the new capabilities of the MultispeQ, the team has been working to update the Android App. You will receive email or popup notifications about how to update your App. (You absolutely need this update to use the new devices, but it will still work with V1.0.).
