Excel displays our time stamp incorrectly. If you were to open the data file in Notepad you would see the correct time format. To correct the data in Excel, Highlight all of column A, right click on the highlighted region and select Format Cells. Under the Number tab select Custom, Scroll to the bottom of the list that appears and select “m/d/yyyy h:mm”. You will need to add “:ss.000” to the end of this, so it looks like this “m/d/yyyy h:mm:ss.000” . Setting the cells to this will give you the highest resolution that Excel can show.
Wireless Sensor Networks
We use Universal Coordinated Time (UTC) to collect data on all of our devices. There is no provision to set the time to a local time zone.
The IEPE-Link™ -LXRS® accepts inputs from most IEPE sensors using the industry standard 10-32 mini-coaxial connector and 2.3 mA constant current excitation.
Yes. The ENV-Link-Mini provides support for wind speed and wind direction indicators.
An example of instruments that have been proven are:
There is no self-test function on the WSDA-Base-101 Analog Base Station to test the analog outputs.
However, each channel can be tested by using whatever wireless node you have.
In Node Commander software, on the analog pairing screen, there is a check box for "Float". What is the function of this check box?
If the node is configured to send data to the base station in floating point mode, you need to enable this checkbox and set the 0-3 volt scaling.
The WSDA-RGD (with internal GX3 inertial sensor) is configured to produce the following messages on startup.
GPS Data (1 Hz):
- UTC Time
- LLH Position
- NED Velocity
AHRS Data (100 Hz):
- Euler Angles
From this output the WSDA logs:
GPS (1 Hz):
- height above ellipsoid
- height above MSL
- horizontal accuracy
- vertical accuracy
AHRS (100 Hz):
As a general rule, you can calculate the battery life of a wireless node by dividing the amp hours of charge on the battery by the amps consumed during sampling.
However, new LXRS functions such as synchronized sampling, beaconing, etc. will not be available for your older node.
All LORD MicroStrain wireless sensor nodes, wireless base stations, and wireless sensor data aggregators are shipped from the factory with their radio frequency set to channel 15 (2.425 GHz).
