Startup

Both the FF310T and FF310R are factory-supplied with batteries. To install the batteries follow the steps below:

1. Open the battery drawer at the back of each unit (factory-supplied batteries are disconnected).
2. Remove the battery, and connect it observing the polarity of the battery connector, repeating the operation on both units.
3. Press the On/Off button on the FF310T, the green LED will start fl ashing. If the green LED does not start flashing, check the battery polarity and reinstall if necessary. To turn the unit off , press the On/Off button again.
4. Press the On/Off button on the FF310R, the green LED will turn on. If the green LED does not turn on, check the battery polarity and reinstall if necessary. To turn the unit off press the On/Off button again.

Turning On and Off the FF310T and FF310R

• FF310T
  The transmitter is turned on and off by momentarily pressing the On/Off button, and it must be turned off manually after use by pressing the On/Off button. Before storing the unit check to make sure that all lights are off , failure to do so will result in a much shorter battery life.

• FF310R
  The receiver can be turned on and off manually by momentarily pressing the On/Off button, however after 3 minutes of not being used, it will turn off automatically to conserve battery power. Turning the unit off manually will prolong battery life.

• Low battery indicator
  From time to time the batteries on both units will need to be replaced. When the battery is below the minimum operating voltage, upon turning the unit on (FF310T and FF310R) both lights will fl ash for 1 second and the unit will turn off automatically. In this case replace the batteries with a new set of 9 Volt alkaline batteries. To install the new batteries, follow the instructions in the preceding section: 2 – Start Up.

Setting the sensitivity level

The FF310R has three user-selectable sensitivity ranges: ‘Low’, ‘Medium’ and ‘High’. These ranges allow the technician to choose the degree of sensitivity most suitable to the particular detection being performed.

Checking the current sensitivity setting:

The FF310R’s current sensitivity setting is displayed when the On/Off button is pressed for 2 or 3 seconds while the unit is ‘ON’ (steady green indicator on). The high sensitivity setting generates a quick triple fl ashing of the green LED, a double fl ashing in the medium sensitivity range and a single fl ashing indicates a low sensitivity level setting.

When turned off, the FF310R will retain the last selected sensitivity setting.

Procedure to select the FF310R’s range:

1. The unit should be on, if not, turn it on by momentarily pressing the On/Off button.
2. Press and hold the On/Off button for approximately 3 seconds until a beeping and fl ashing occurs. This initial beeping and fl ashing indicates the current sensitivity level setting. By holding the On/Off button pressed, the FF310R will cycle to the next sensitivity setting following the pattern indicated below:
3. Low Sensitivity: single (1) fl ash and beep.
4. Medium Sensitivity: double (2) fl ash and beep.
5. High Sensitivity: Triple (3) fl ash and beep.

The sensitivity level is selected in the following sequence:

For example: If the FF310R unit is set to ‘MEDIUM’, in order to set the sensitivity to LOW, press the On/Off button until a double beep and fl ashing occurs (current setting), keep holding the button pressed and a triple beeping and fl ashing occurs (setting now is HIGH), keep holding the button pressed, until a single fl ash and beep indicates that the new setting is LOW.

How to use the sensor:

The probe of the FF310R is built of coiled steel equipped with a sensor (yellow cylinder), and can be bent as needed, in order to reach wires in congested or difficult areas. Depending on the circuit characteristics and the sensitivity setting, the probe’s sensor will pick-up the signal from the wire in a wide range of positions . However for the best possible range, the FF310R’s sensor (yellow cylinder) should be positioned perpendicular ( at 90°) to the wire being traced and either above or below it, as shown in Fig. 1 below.

Locating short circuits

Refer to the Hook Up Reference Chart in Page 6.

1. Observe the limits and safety precautions at all times (refer to the beginning of this handbook).

2. Connect the FF310T in series with the short-circuited wire, making sure one of the unit’s clips is connected to the circuit’s positive supply (or vice versa for vehicles with positive supply connected to chassis). A fuse socket connector (in place of the blown fuse), a connector, etc., provides a convenient hook up as shown in Fig. 2 and Fig. 3 in Page 6.

3. Switch the FF310T on by pressing the On/Off button and observe if the red LED on the FF310T starts fl ashing. If not check the connections, power supply, and in the case of having connected the unit to any place other than the fuse socket, check that the circuit’s fuse is installed and in working condition (not open). If necessary replace with a new fuse with the same ratings.

4. Switch the FF310R on, insuring the green LED turns on.
   Verify that the FF310R is set to the lowest sensitivity level (single green LED fl ash).

5. Slowly sweep the wire, conduit, etc., ensuring the FF310R’s sensor is perpendicular and above or below the wire being traced and as close as possible to it .

6. Follow the wire or check it at diff erent points, starting from the FF310T and moving towards the load (accessory, light , etc.) observing the positioning of the sensor as indicated above. Continue this procedure while the audio signal (beeping sound) and visual signal (fl ashing red LED light) indicates the integrity of the circuit. If beeping and fl ashing slows down or stops it indicates that the sensor is either moving away from the faulty wire or it has passed beyond the short circuit point.

7. If difficult or impossible to get the FF310R to pick-up any signal, then increase the sensitivity level, and start again from step 6.6.

8. Double check positioning the sensor before and after the suspected place. If the short circuit point has been located, the audio/visual indicators will show circuit integrity on for one position, but not for the other.

9. The short circuit is located in the area where the audio/visual signal stops or  changes signifi cantly.

10. When the test is completed, switch off the FF310T unit pressing the On/Off button and disconnect from circuit.
    Note: The closer the FF310R’s sensor is to the wire carrying the signal, the faster the beeping and the fl ashing will be. Some times it will prove advantageous to reduce the sensitivity level to pint point more accurately the faulty area.

Wire tracing

Wire tracing hook up and procedures are essentially the same as for locating short circuits. The FF310T sees the load (light bulb, accessory, etc.) as a weak short circuit or connection to ground. For wire tracing simply follow the wire with positive (beeping and fl ashing) audio/visual indicator’s feedback on the FF310R from source to load.

For step by step directions please refer to point 6– Locating Short Circuits, for some hints and specifi c diff erences refer to the notes below:

The type and size of load connected to the circuit (impedance or resistance to ground) determines the amount of current allowed to fl ow in the circuit. Small loads (low Watt-age lamps, electronic systems, etc.) will reduce the range of the FF310R accordingly. In cases where the full range of the FF310R is required to follow the wire, it may prove advantageous to use one of the two methods described below:

• Tracing wires downstream (from supply to load): replacing the load for a full short circuit allows the FF310R to work at its maximum capabilities. Before proceeding, remove all electrical power from the circuit, connect the FF310T in series with the wire to trace, short circuit the load to ground (refer to Hook Up Reference Chart Fig.2 and 3), then reconnect power and follow instructions in section 6 – Locating Short Circuits.
• Tracing wires upstream (from load to supply): If more convenient, wires can also be traced the other way around, by replacing the load with the FF310T (Fig. 5 of Hook Up reference chart). To do this, fi rst remove power from the circuit, disconnect the load and connect the FF310T in its place. Apply power to the circuit and follow instructions in section 6 – Locating Short Circuits.

Locating current leaks

Hook up and procedures for locating current leaks are essentially the same as for locating short circuits. The FF310T sees the leak as a weak short circuit or connection to ground. For locating a current leak simply follow the wire with positive (beeping and fl ashing) audio/visual indicator’s feedback on the FF310R, from source to leak location (short circuit).

For step by step directions please refer to point 6 – Locating Short Circuits, for some hints and specifi c diff erences refer to the notes below:

Current leak notes:

• The type and size of the leak in the circuit (impedance or resistance to ground) determines the amount of current fl owing in the circuit. Small leaks (i.e. low current) will reduce the range of the FF310R accordingly. In all cases the FF310R’s sensor should be positioned as close as possible to the wires, in order to maximize the signal captured by the FF310R, and set to a higher sensitivity level . For hook up refer to the Hook Up Reference Chart Fig. 2 and 3 in Page 6.

Locating open circuits

Refer to the Hook Up Reference Chart in Page 6.

1. Observe the limits and safety precautions at all times (refer to the beginning of this handbook)
2. Connect the FF310T in series with the open ended wire, making sure one of the unit’s clips is connected to the circuit’s positive supply or ground . A fuse socket (with the fuse removed), a connector, etc., provides a convenient hook up as shown in Fig. 2, 3, 4 and 5 of the Hook Up Reference Chart.
3. Make sure that the clips are fi rmly attached to their connection points, and switchthe FF310T on by pressing the On/Off button. Observe if the green LED on the FF310T starts fl ashing. In the case of having connected the unit to any place other than the fuse socket, check that the circuit’s fuse is installed and in working condition (not open). If necessary replace with a new fuse with same rating.
4. Swi tch the FF310R on, insuring the green LED turns on and set i f necessary the sensitivity level to “LOW”.
5. Slowly sweep the wire with the FF310R, ensuring the sensor is perpendicular to and above or below the wire being traced and as close as possible to it .
6. Follow the wire or check it at diff erent points, starting from the FF310T and moving towards the load (accessory, light, etc.), observing the positioning of the sensor as indicated above. Continue this procedure while the audio signal (beeping sound) and visual signal (fl ashing green LED light) indicates the integrity of the circuit. If beeping and fl ashing slows or stops, it indicates that the sensor is either moving away from the wire or it has passed beyond the open, break or badconnection in the circuit.
7. If diffi cult or impossible to get the FF310R to pick-up any signal, then increase the sensitivity level and start again from step 9.5.
8. Double check by positioning the sensor before and after the suspected place. If the open circuit point has been located, the audio/visual indicators will show circuit integrity on one side, and not on the other.
9. At this point, where the audio/visual signal stops, you have found the open circuit.
10. When the test is completed, switch off the FF310T unit pressing the On/Off button and disconnect from circuit. You may also switch off the FF310R by pressing the On/ Off button on the unit. However to conserve power, the FF310R will automatically turn off after 3 minutes of not being used.

Note: The closer the FF310R’s sensor is to the wire carrying the signal, the faster the beeping and the fl ashing will be.

Wire identification

Refer to the Hook Up Reference Chart in Page 6.

Wiring can be identifi ed by following the hook up and procedures for locating short circuits or open circuits, depending on the particular confi guration of the circuit.

• For identifying wires with load connected: Connect the FF310T as described in section ‘6- Locating Short Circuits’ to the circuit to be identified, then proceed to scan all suspected wiring with the FF310R’s sensor until the fl ashing and beeping is at its maximum. In the case of tightly packed wires ( bundles, conduits, etc.), it may be necessary to spread these apart to facilitate the identifi cation process of a particular wire.
• For identifying wires without load connected: Connect the FF310T as described in section ‘9- Locating Open Circuits’ to the circuit to be identifi ed, then proceed to scan all suspected wiring with the FF310R’s sensor, until the fl ashing and beeping is at its maximum. In the case of tightly packed wires ( bundles, conduits, etc.), it may be necessary to spread these apart to facilitate the identifi cation process of a particular wire.

General procedures

• Short and open circuit operation – Differences:
  The FF310 FaultFinder set uses two diff erent types of signals to trace either short or open circuits. Understanding its diff erences, as explained in the following paragraphs will allow you to make the most eff ective use of this versatile tool.

• Working with open circuits
  On detection of an open circuit, the FF310T injects a special radio signal into the circuit, which can be picked up by the FF310R’s sensor. When tracing an open circuit, keep in mind that RF (radio frequency) signals injected in the faulty wire being traced, will be easily absorbed by any other conductor nearby. (e.g.: other wires, metal frames).The eff ect of this absorption may vary from a reduction in the FF310R’s range, to a total shielding of the signal with no detection being possible at all (See Fig. 6).
  Fig. 6 – Detection fi eld when tracing open circuit with the FF310R
  In order to avoid confusing a shielded portion of the faulty wire with the actual fault on it, the circuit should be checked on in several places to confi rm that no signal is detected on the other side of the suspected faulty section.

• Working with short circuits (and tracing circuits)
  When the FF310T detects a short circuit (or closed circuit), it injects pulses of electrical current in the wires, which generate magnetic fi elds. Unlike radio signals, magnetic fi elds are not easily absorbed by nearby conductors and therefore can be picked up by the FF310R’s sensor in a wider range of situations (See Fig. 7).

• Some circuit characteristics that may aff ect the tracing of a wire:

  • Electromagnetic loop size and geometry, etc. may affect the range of the FF310R. For example for circuits in which the live and ground (return) wire run parallel and close to each other in the same circuit, the two magnetic fields interaction may weaken the signal, thereby reducing the FF310R range.
  • Wires enclosed or tightly lining the metal frame or body of the vehicle, (i.e.: door frames), have the same eff ects as having the live and ground wires running in parallel in the same circuit since, the metal frame or vehicle body will be acting as a ground wire. Another unfavorable factor may be due to the channeling eff ect steel parts have on magnetic fi elds. These two cases, individually or combined, will reduce and sometimes impede the tracing of the wire sections aff ected.

Hint: Whenever possible the short circuit mode of operation should be used, because it provides with the best tracing capabilities.

Special tracing procedures

• In all cases, fi rst set the FF310R at the lower sensitivity level and increase it as necessary. Proceed as indicated in the sections of this User’s Manual applicable to your situation.
• Always after locating a probable fault area, verify several points in the wires on both sides (before and after) the suspected area. The signal should be present at only one side of the fault (open or short). This procedure will help avoid confusing a signal loss with the actual trouble point.

Wire bundles and conduits:

• Special care should be given in the case of tracing a wire inside a bundle or conduit when there is a split. In this case it may be possible to follow the wrong branch for a short distance and still receive a positive audio/visual indication.
• To avoid following the wrong path, which could happen if the FF310R’s sensor picks up the signal from the other nearby branch of the circuit, the branches should be swept maintaining the sensor outside the apex area between the split, as shown in Fig. 8.
• Careful attention should be paid to the beeping and fl ashing speed of the FF310R unit indicators, as these provide the necessary feedback to evaluate the proximity of the sensor to the wire being traced.

How to increase the pick up range when tracing wires

• When tracing or identifying wires connected to lightly loaded circuit (low currents), this reduces the range of pick up signifi cantly. A possible solution is after connecting the FF310T in series with the circuit to trace, is to replace the load (light bulb, module, etc.) with a direct connection to ground. This allows the FF310T to inject a more powerful signal which is easier to detect.
• For the cases in which it is suspected the layout of the wires is the cause of a very difficult to pick up or weak signal, a dramatic increase of the range can be accomplished by “spreading” the circuit.
• The spreading the circuit is achieved by connecting a jumper wire between the live wire (preferably at a termination point in the circuit such as a light bulb socket, switch, etc.), and a ground point somewhere else in the vehicle ( see Fig. 9). Thislast method should be used only as “last resource” and with the FF310R set to low sensitivity, as it could make the pinpointing of the precise location more diffi cult due to the much increased range.
• Always verify that the FF310T is connected in series with the circuit being tested and that its red indicator light is on, as this confi rms a proper connection and will limit the amount of current fl owing in the circuit.

Circuits with multiple loads or branches

• When tracing circuits connected to, or which are powering multiple loads and/or branches (See Fig. 10), and when these circuits are active or live, the bulk of the current injected into the circuit by the FF310T will be directed to the shorted branch of the circuit. However smaller amounts of current (or stray currents) will fl ow to theother branches as long these provide a path to ground (i.e. close the circuit).
• These stray currents present in the non-shorted branches of the circuit, and depending on the circuit confi guration and physical layout of the wires, could be picked up by the FF310R, making the tracing procedures confusing, and even misleading.
• The simplest and most eff ective way to deal with these cases, is to disconnect or remove all the loads from the circuit being traced (i.e. removing light bulbs in example shown in Fig. 10).
