AVA MONITORING FAQs
What does the AvaTrace measure exactly?
What is the sensitivity of the Geophone sensor?
Why won't my unit connect to AvaNet?
What are the recommended battery levels for safe use of the AvaTrace?
What is power saving mode?
If a local SIM card is installed correctly but cannot connect to the network, is the international SIM activated?
No. If a local SIM card is installed correctly (detected by the instrument) the international eSIM will not be activated automatically.
My AvaTrace has been stolen. Can I use GPS to locate it?
How do I know that the AvaTrace is connected to AvaNet and is logging data?
What is the noise floor of the AvaTrace?
What does the arrow on the geophone represent?
The arrow on the top of the geophone represents the longitudinal axis. The arrow should always be visible when looking directly down on the sensor. This is good rule-of-thumb for checking correct sensor orientation.
AvaNet (Measuring Points)
How do I view additional columns in the table format?
How do I return all true entries in an AvaNet column?
==true (alternative for all false entries is ==false)
Can I download waveform data for measured events?
How do I filter results in an AvaNet table?
Filtering tables is a great way to find the data you are looking for quickly. If you know the right command you may write it straight into the text box at the top of the relevant column. If not, click the? next to this box to help generate the code required for your filter.
How do I change the number of displayed lines per page in table view?
Select the menu item ”Preferences” which you will find in the menu ”Settings”. In the window that opens, select the desired number of rows and then click ”Finish”. The number of rows is now saved for future logins.
How do I search for values within a specific time period?
Sometimes you may want to display measurements for a period of time regardless of the date, e.g. every day between 07:00 – 18:00. In this case, you can use the "Time of day” instead of the column ”Time” which includes dates. Normally, the column ”Time of day” isn’t displayed, but you may add it by clicking the ”select columns” above the table. To enter the desired time interval, click the question mark to the left of the search field column ”Time of day”. This opens the dialog for advanced options that make your job of building up the search string. For example, to find out the range of 07: 00 – 18:00, do the following: 1) Select the option ”not before,” and enter 7:00 into the text field and click the ”And” 2) Select the ”not after:” and enter 18:00 into the text field and click the ”And” You have the following search string in the text field: > = 07:00:00 && <= 18:00:00 Click ”Search” to execute the search. The dialog closes and the table is updated. You can see the search string in the search field for the column ”Time of day” If you want to limit the search to be between certain dates, include the column ”Time” and simply choose the desired dates.
I am missing some older data in AvaNet. Is it still accessible?
Yes. To improve navigation speed and usability AvaNet hides older data. To see all data associated with that measurement point click full query in the menu above the table. To revert back to the reduced table, click partial query.
Why are settings in the Instrument Panel highlighted yellow or red?
What is the 'Raw Waveforms' checkbox in the Instrument Panel (Channel)?
By default, the AvaTrace stores filtered waveforms according to the selected channel filter profiles. If the *Raw Waveforms* box is ticked, raw unfiltered waveforms are be stored. This may be used when the end user would like to post-process the raw waveform data to extract information such as Whole Body Vibration (WBV) stats. N.B. All alarms and analytics will still be based on the filtered data.
What does the 'Auto Disconnect' checkbox in the instrument panel do?
By default, an AvaTrace M80 will automatically disconnect after successsfully downloading new settings and/or uploading any current data. If the 'Auto Disconnet' checkbox is left unchecked, then the next time the units connects it will hold the radio connection indefinitely. This may be helpful in situations such as attended vibration monitoring. We highly recommend leaving 'Auto Disconnect' enabled for long-term use to improve battery power conservation.
What do the signal strength values in the log file read out represent?
Why can I not add an instrument to a new project?
How do I move an instrument to a new measuring point?
If you want to move to a new measuring point within the same project, select the measuring point in the list shown in the channel tab in the instrument panel. If you want to move the instrument to a measuring point in another project, detach the measuring point in the current project, switch to the new project and attach the new measuring point.
What is a Measuring Point Group?
When generating a 'Vibrations, triax and air blast' measuring point in project set up, AvaNet automatically generates three measuring points associated with a single location: Transverse, Vertical and Longitudinal along with a fourth 'group' point which is associated with the three directional points. For a measurement point assigned demo, the associated points will be would be labelled demo-tram, demo-long, demo-vert and demo (The latter being the group measurement point). A group measurement point can also be created manually. The measurements for which there is a waveform uploaded to AvaNet appear in this group. Note that it does not include all measurements above the trigger level unless they also have a waveform in AvaNet. For all measurements above the trigger level, a waveform will exist on the unit, but they will not be uploaded to AvaNet unless the waveform threshold has been exceeded. If a measurement has exceeded the trigger level but not the waveform threshold the waveform may still be requested and thus uploaded to AvaNet. This is not a fast process and is not recommended as standard practice. Once the waveform has been requested and thus exists in AvaNet the measurement will appear in the Group Point.
Why is the Measuring Point Group table empty?
Why don't I have an instrument error alarm group?
The most common error here is selecting the finish button within the project set up wizard before the alarm set up section. Ensure you keep clicking next until the end of the wizard. Another issue may be related to user permissions. Contact Resonate Systems to ensure you have the appropriate permissions.
An SMS-alarm directly from the instrument arrives faster compared to the one sent from the alarm group in the AvaNet. SMS from the instrument are sent directly through your local network whereas SMS from AvaNet must be sent to the cloud and then to your phone, thus the slightly longer delay. Alarms sent directly from the instrument are limited to two recipients. Whereas, SMS from AvaNet may be sent to multiple recipients. To add a recipient to an alarm group it is required that the recipient is a registered user of the AvaNet. To send an alarm directly from the instrument only requires a cellphone number.
What is a Measuring Point Day (MPD)?
When an AvaTrace M80 unit connects to AvaNet a 'Measuring Point Day' (MPD) is registered. The unit does not have to be sampling for this to occur. Simply a connection is sufficient to accumulate an MPD. MDPs are used for billing purposes to determine the total AvaNet daily access fees for unit owners.
I'm thinking about purchasing an AvaTrace device. Are there any additional operational costs/subscriptions to use this product?
What is a 'self-test' and when does it occur?
A 'self-test' is the method by which the AvaTrace determines correct geophone sensor operation. A 'self-test' occurs when an AvaTrace commences sampling and then once a day, generally overnight, for each day the unit is active. A 'self-test' will also be carried out if a channel’s status changes from inactive to active whilst the unit is sampling.
Does the log file report each time a self-test error is conducted?
How do I rectify a self-test error?
A self-test error occurs when there is an issue with the incoming signal from the geophone. The most common source is a misaligned geophone. Ensure that the vertical (up), and horizontal (lateral) axis of the geophone are aligned appropriately. For visual reference, the arrow on the geophone should always point in the longitudinal axis.Other checks that you can carry out include checking that the trans cable is connected to the trans input and the vertical cable is connected to the vertical input etc. Checking that the TNC connectors are fully screwed in. You may try un-connecting and reconnecting these points. Checking the number and location of connected cables corresponds with the active channels in AvaNet. Checking that the cable isn’t damaged. Please note that once a self-test error has been triggered, the warning in AvaNet will only be removed by a positive self-test. Self-tests however are usually completed after the unit has connected to AvaNet on measurement start, thus the results will not be pushed to AvaNet until there is a reason to connect again (a positive self-test error does not trigger connection). If the measurement button is not flashing fast there is no error associated with the incoming signal. If you wish to remove the warning message in AvaNet, simply press the connect button.
What is a DPU Error Code warning?
This error can be ignored. It is a warning relevant to the developers that gives them a feel for how the power is affecting the units. It does not affect the general operation of the unit.
