RST MEMS Tilt Meter - Digital

RST’s MEMS In-Place Tilt Meters measure tilt in either one or two axial planes perpendicular to the surface of the base plate. Digital bus allows several tiltmeters to be daisy-chained on a single cable up to 1200 meters in length.

Adding a RST MEMS Tiltmeter

Ensure that the THREAD is turned on and connected to the RST MEMS Tiltmeter directly via one of it's Device ports

1.  Navigate to the Network Module

2.  Press the  button directly on a THREAD to add a Device to it. If your THREAD does not appear here, you may still need to Add Your THREAD as a Connection.

3.  You may also add a device from the  button in the Devices & Sensors Section 

4.  Begin by typing in "RST Tiltmeter" and select the name once it autocompletes in the search boxScreen_Shot_2018-07-10_at_11.50.02_AM.png

5.  Type in the Connect Code of the THREAD that the Device will be connected to. It will already be pre-filled if the  button on the THREAD was used. 

6.  Next, select the THREAD communication port that the device is plugged into, Device 1 or 2.

7.  Next, select the Segment Information by clicking Edit Configuration.

Add in tiltmeter serial number here.  If you are bussing multiple sensors select number of segments and add all serial numbers here. 

8.  Press     to write the settings. Your device should now connect to sensemetrics indicated by a green icon Screen_Shot_2017-03-09_at_3.44.02_PM.png

Sensor Configuration

To start viewing all Tiltmeter calculations, certain setup parameters will need to be entered.  

Below is a list of the modifiable parameters and the metrics it will affect. 

Navigate to the sensor configuration page of the Tiltmeter you wish to modify

Sensor Orientation

The X/Y Axis displayed in sensemetrics will always be fixed relative to the Tiltmeter's A and B.

X = A+

Y = B+

Reference Date - 

The reference date will specify the first date used when calculating delta metrics indicated with the ∆

Specify the Reference date to use any ∆ Delta calculations

*Note- If no reference date is chosen, delta calculations will automatically use the first data point in your time range selected as the reference date. 

Device Azimuth - Northing/Easting

The Tiltmeter does not inherently know North/East. In order for North/East to be correctly represented, you will need to specify the Device azimuth. This is done by measuring the angle from North to the B axis in a clockwise direction.

 Specify the Sensor Azimuth to use Northing/Easting calculations

Structure Azimuth - Transverse/Longitudinal 

This field will allow you to orient the Transverse/Longitudinal Axis in any desired direction. It is useful for finding movement in the direction of a specific structure or any point of reference. See the Structure Azimuth Section on instructions on how to properly set it up.

Specify the Structure Azimuth to use Transverse/Longitudinal calculations

Gauge Length - X/Y

Enter the Gauge Length or the Height of the structure from the base to top of the structure. This will use a trig calculation with the Tilt X/Y angle to create a X/Y Vector at the top of the structure. 

Specify the Structure Height to use X/Y calculations and allow vectors in Map View.
