About the Mantis

The Mantis is the first live cable tester module that monitors energized and un-energized cable runs and electrical circuits around-the-clock. It detects, locates, and characterizes faults, either static/persistent or intermittent to show where and when they occur. This information can then be transmitted either wirelessly or over data cables for alerts and instant response to the events.

Note:

Terminal Block

Connect the cables to the terminal block for testing.

RJ45 Jack

Ethernet connector for the Mantis.

Cable Testing: The Mantis offers three test modes.

Fault Location: The Fault Location test is a good test to start with. It will scan the wire under test to find either a persistent open or short fault. Operating in this mode is recommended for non-powered cables only.

Live Intermittent Fault Detection: Live IFD scans the wire continuously to identify faults that may not be detected by the Fault Location test if the fault condition changes with time.

Live Sweep Fault Detection: Live Sweep mode is similar to

Live IFD mode, but uses multi-frequency scanning in order to provide better distance to fault accuracy over the entire length of an extremely long cable. Live IFD should be used when intermittent fault conditions occur very rapidly (less than 5 seconds).

Cable Types and VOP: The Mantis has the ability to save new cable types and VOP values.

Mantis Alerts

The Mantis is equipped with an alert system for 24/7 monitoring. The

Mantis can send an email alert if any of the following occur:



A fault occurs during intermittent testing (IFD).



A fault occurs during Live Sweep Fault Detection.



The power supply to the Mantis is disconnected.



The battery reaches critical battery power (10%).



When AC power is restored.

Cable Faults

The Mantis is capable of scanning a cable in three modes; Fault

Location, Live IFD, and Live Sweep, all enabling the user to identify if an open or short circuit condition exists on the cable. The table below describes open and short circuit fault conditions.

Cable

Faults

Description

An “Open” fault appears when a wire that should be connected from point A to point B has no electrical connection between those points.

Open

The “Short” fault appears when the two wires within a cable are electrically connected. This is also known as a short circuit

Windows PC User Interface

This section of the manual provides a preview of the Mantis Windows PC application interface and shows screenshots of some available screens used. There is a separate section (Connecting to the Mantis) that provides details for installing the Mantis Application on your Windows

PC, then connecting through a network to the Mantis.

The first screen you see when you open the application is the Log-in

screen:

After successfully logging in to the Mantis unit (for additional detail on login user name and password, see Connecting to the Mantis section), the Windows PC application brings you to the Main menu

page:

Fault Location: This mode of testing indicates where the closest reflection is located. This can either be the end of the cable or the location of a hard fault, whichever is closest to the point where the

Mantis is connected.

Live Intermittent Fault Detection: Cable and wiring systems can have fault conditions that come and go intermittently, which means that the fault can disappear and reappear at any time. Live IFD enables a technician to find such a fault condition. A significant change in the condition of the wire or cable under test (short, open, etc.) that is different than the initial condition of the wire will be reported as a fault.

The following screen shows an IFD test while it is running:

Live Sweep: Cable and wiring systems can have fault conditions that come and go intermittently, which means that the fault condition can disappear and reappear at any time. Live Sweep enables a technician to find intermittent fault conditions on extremely long cables (≤ 6 kilometers), but also retains the ability to detect short and medium distance faults. Multiple operating frequencies are utilized to obtain the most accurate distance to fault results over the entire length of a long cable.

File Browser: You can view previously saved data that provides detail for reporting or analysis. Files are saved to the Mantis and must be transferred to the Windows PC by selecting a file and clicking on the

Copy button.

LOGOUT: Logout of the Mantis from the Main page using the

LOGOUT option at the top. If there is a Live IFD test or Live Sweep test running, the Window’s PC software will take you automatically to the test mode associated with the currently running test.

General Settings Menu:

Live IFD tests to use Advanced Intermittent Test settings by checking the box. The unchecked box (default) means the

Mantis is configured to use “Simple Mode” which loads all the default settings for cable scans at any frequency chosen.

Unit of Measure either Standard or Metric. This configures the waveform graphs and distance to fault for all detection modes.

Email Alert Language is set to English (default) or Italian

(Additional language support will be added as needs arise at no additional charge).

The menus at the top right allow you to change Mantis Device settings, Network settings, Email settings, and Email List. More specific details about these menus are discussed in the User Settings section.

ABOUT menu: Provides information about the software/hardware versions active on the current platform.

Fault Location, Live IFD, and Live Sweep Test

The Mantis offers three test modes to measure and identify faults on a cable. The Fault Location test is a good test to start with. It will scan the wire being tested to find either an open or a short fault. It is not meant to be used on powered cables. The Live IFD test scans the wire continuously looking for intermittent faults that may not be detected using the Fault Location mode and is intended for cables < 1000 feet.

The Live Sweep test uses the same scan characteristics as in a Live IFD test, but separately steps through multiple operating frequencies and scan operations. Live Sweep mode is able to monitor extremely long cables, but retains the ability to detect short and medium range faults.

Fault Location Test

The Mantis can conduct tests for Fault Location faults to test for an existing open or short circuit. Fault Location mode is not used for testing intermittent faults. Fault Location is not meant to be used on

A/C powered cables and may not provide accurate results in this mode.

Set Up



Connect the cable to be tested to the Mantis terminal block.



Connect the DC power source to the Mantis terminal block.

Use additional adapters if needed.



From the Main page of the Mantis Application, select the Fault Location icon. This brings up the Fault

Location Test page.

Select your Cable Type



Select CABLE LIST in the upper right corner of the test screen.



In the drop down menu that appears, select the appropriate cable type being tested. This step ensures accuracy of the test by using the correct VOP that is associated with the cable type.



To add or edit a cable type, refer to Cable Types and VOP section.

Fault Location Testing and Results



Select the Test button.



The result displays the fault type, distance to fault, and a graph of the waveform from the test. The fault is displayed in the graph with a vertical line at the reported fault location. An example is shown below.

Note: If the distance to fault shown is at or near zero, it is likely that the terminal block connections need to be checked and/or adjusted. Additionally, if the test result shows ‘Unknown’, the distance to fault may be too far away for the Mantis to detect the fault with certainty.

For a more detailed explanation of test results, refer to the Interpreting

Test Results section of this manual.



To save the Fault Location test, click Save File in the upper right corner of the window.

Cable Types and VOP

To edit an existing cable or create a new cable, select the CABLE LIST button. This will display a cable list window as shown in the following screen.

Add New Cable Type



To create a new cable type select NEW.



To change the name of the new cable select the text box and enter the name of the cable being created.



Change the VOP to the correct VOP of the cable being tested.

Appendix A of this manual contains typical cable types and VOP values.

Note: If the VOP is unknown see Calculate Unknown VOP section. The range for VOP is 0% - 99%.

Edit Cable Properties



To edit a current cable type, select EDIT.



Select the cable to be edited from the library of cables.



The details of the cable will be displayed in the window.



Edit the cable name or VOP value as needed by selecting each field and changing them to fit proper cable properties.



Click OK to save changes.

Calculate Unknown VOP

If a cable is not found in the pre-populated list and the VOP is unknown or if the VOP of an existing cable is not accurate, calibration of the VOP may be necessary. A cable of known length 25ft – 200 ft. is needed to calculate the VOP. Longer lengths (up to 500 ft.) will result in a more accurate VOP.



Connect the known length of cable to the Mantis.



From the main Mantis Application, select the Fault Location icon.



Select TEST to perform a Fault Location test.



If the result of the Fault Location test is greater than the known cable length, the VOP is set too high.



If the length of the Fault Location test is less than the known cable length, the VOP is set too low.

Use the calculation below as an example of how to determine the

VOP for an unknown cable:

VOP estimate = 84.6%

Actual cable length = 30 feet

Reported fault location = 38.5 feet

VOP Actual = VOP Estimate* (Cable Length/Reported Fault Location)

= 0.846 (30/38.5)

= 64.58%



To create a new cable type with another VOP, select CABLE LIST then select NEW. To edit an existing cable, select a cable from the cable list then select EDIT.



Enter or edit the cable name and VOP, then select OK.



Run the Fault Location test with the new VOP and readjust until the length of the known cable is displayed or is very close. It may also be helpful and more accurate to use longer cables where possible, but a different test frequency will be necessary depending on the length of the cable and distance to fault.

Interpreting Test Results

The Mantis evaluates cable faults using SSTDR which is capable of detecting/locating/reporting both intermittent and hard cable faults.

The Mantis transmits a small but recognizable signal along a pair of wires or cable which will reflect off impedance changes. When the reflection of this signal reaches the launch point, the distance to the impedance change is determined by the velocity of propagation (VOP), which is a characteristic of every cable. The table below displays the reflections that would be seen for both a short and open circuit fault.

Type

Launch Waveform with no detectable fault

Waveform

Short Circuit Fault

Open Circuit Fault

The waveform shape on the left is the initial start of the waveform, or location “zero”. The waveform shapes shown to the right correspond to fault reflections. The behavior of ‘up-down-up’ vs. ‘down-up-down’ indicates a short or an open circuit, respectively. The time delay between the initial reflection (location = 0, where the Mantis is connected to the wire) and the reflection from the fault or end of the wire indicates the location of the fault. The time delay is converted to distance using VOP, which is why using the correct VOP for the type of cable is necessary an accurate measurement.

The Mantis uses this information to display the distance and type of fault. For the Fault Location test mode, several different scans are sent down the cable and the optimum scan chosen. For Live Intermittent

Fault Detection, continuous scans (single frequency) are used to monitor the cable for faults in real-time.

Fault Location Test:

The Fault Location test shown below displays a short at the point where fault is indicated. The SSTDR signature can be seen at the beginning of the test and the short appears as an ‘up-down-up’ reflection at some point during the scanning process.



To compare various frequencies tested, click on the Exit button to view all of the simplified waveforms for each frequency used during the test. Scroll up or down to view waveforms at the top or bottom of the list shown then click on the waveform you wish to select for a full screen view of only that waveform by itself.

Note: Any waveforms (among the full list) may be viewed, but the frequency that was chosen for final result during this test is the same waveform that was shown on the main Fault Location Test screen

(and matches the distance to fault reading shown in text).

Waveform Analysis:

The following waveform is an example of an Intermittent (IFD) test result, but the analysis can also be applied to the Fault Location waveforms.



The buttons displayed at the bottom of the screen provide a legend for the graph and can be selected to provide a single graph or selection of graphs.



The

Reference

graph displays the waveform of the transmitted signal and its reflections that are used as a reference for the wire scan with cables connected (known good state of the cable) before a fault is determined.



The

Focus

graph displays the waveform (detected change; impedance signature) of the wire during a fault condition.



The

Difference

graph displays the magnitude difference between the reference and focus graph (difference between the before/after states of the cable). The difference is used to determine the type of fault and its magnitude.



In the above waveform, the fault and reference appear at the same place in this graph, because the fault (short) has occurred at the end of the cable. The reference is displaying at the end of the cable, and the fault is also displayed at the same place.

User Settings

Mantis Application (Log-in Page)



The Mantis client list is accessed from the Mantis log-in menu and by selecting CLIENT LIST. This list is only for use in Wi-Fi

Client or Wired Client modes.
