APPLICATIONS

Please read this important information!

Intended Use/Use for Intended Purpose
The devices of the EasyTest system are cable and line finders for different purposes. In each case, a tone sender (ETXX0 – short ET) and a contactless receiver  (PXX0 – also called Probe) are required. The ET feeds a search signal intoa cable/line/wire/wire pair; which kind of cables/lines/wire/wire pairs are supported depends on the device. Where it is technically possible, work must be done free of voltage; the maximum allowed voltage is 90 V. In case of electrical cables/lines as part of a electrical installation/system work must always be carried out free of voltage. The maximum length of the cable/line/wire/wire pair is 15 km or 9.3 mi (no load). Through scanning with the Probe, the signal can be found and traced (scanning range 60 cm or 23.6″). The signal is made audible by the Probe (speaker/ earphone jack) and visually indicated (LED). Electrical cables, lines, wires and wire pairs can be found with this method. In addiction, errors and disruptions can be identified.

The devices can be bought individually or as sets (KEX0X) with accessories.

Device Overview

For technical data please refer to chapter Specifications“ auf Seite 39.

Receiver : P310/P410/P510

The Probe is a contact-free test speaker that receives the signals sent by the ET and makes them audible. The green signal strength LED indicates the precise 1 kHz signal from the ET. Interfering signals, e.g. 50 Hz or the harmonics thereof, are filtered out. The P410 has an additional red LED, with which an ISDN UK0 line can be found. This makes it easy to detect an active ISDN UK0 line in e.g. distribution boxes. A flashlight function with pure white light guarantees clear color recognition of the wire markings in dark distribution boxes. The flashlight automatically turns on when the device is turned on and deactivates automatically when it is turned off. The test tip of the Probe is made of fiber-reinforced plastic with a bayonet lock for easy replacement on- site without opening the device. For replacements see data sheet. At the lower end of the Probe there is a connection socket for an earphone (3.5 mm jack), with which signals from greater distances (up to 150 cm) can still be easily tracked. The Probe is switched on and is used by pressing and holding the HIGH or LOW buttons. The HIGH position is the most sensitive level for finding weak signals. In the LOW position, the found wire pair or cable is specified for example.

Symbols on the Device

Tone Sender: ET300/ ET400/ ET500/ET720/ET800

The ET is a tone sender that is connected to the end of the cable/line/wire/ wire/wire pair that is to be searched/tested (connectivity depends on product).

Voltage resistance in case of accidental connection to external voltage:

• ET300 /ET400/ET720/ ET800: 120 V AC
  ET500: 350 V AC

Switching on
After pressing the ON/OFF key, a tone is audible to confirm power-up (ET720/ ET800 only) and the ALT and SOLID LEDs light up briefly. For all other versions, depending on the position of the three-stage slide switch, the following LEDs are used as switch-on information: TONE mode = ALT LED flashes, DATA mode = DATA LED lights up in a dim green, CONT mode = CONT LED flashes briefly.

Switching off
Press the ON/OFF button for longer than 1.5 seconds. The ALT and SOLID LEDslight up briefly and it switches off; ET720 and ET800 sound a shutdown tone. The ET switches off automatically after 90 minutes. If it is needed for longer, the ON/OFF button has to be pressed twice within 1 second after the unit is switched on. To confirm that the timeout override mode has been activated, he SOLID LED flashes briefly. If TONE mode and SOLID are active, this function is taken over by the ALT LED. The ET720/ET800 will sound a short confirmation tone.

Low Batt – battery voltage monitoring
When the device is switched on and the battery falls below a voltage of approx. 6 V, the SOL LED flashes briefly three times every 60 seconds to indicate. In TONE mode, the ALT LED will flash instead.ET720/ET800 also emit a warning tone. ET will switch off automatically when 5 V is reached.

Symbols on the Device

Initial Startup

The devices are powered with 9 V batteries (not included in delivery; exception: KE702 (Telekom), KE801 (Telekom)).

Before inserting batteries, disconnect all test leads and turn off the device. Only use batteries according to the specifications. The battery compartments are on the backside of the devices. Open the battery compartments (Phillips screwdriver PH2 required), insert the batteries, and close the battery compartments again.

Operation

You can use the devices for different tests. To perform them, the ET is put into different modes through the switch on the right side of the device:

• TONE = Sends a tone into the cable/line/wire(s) for finding and tracing
• CONT = continuity and resistance testing
• DATA = Network port test and port finder function (link blink function to identify ports on routers/switches/hubs) (ET400/ET720/ET800 only) In addition, you can find and test fiber optic cables (FO) (ET800 only)

Warning:

• Where technically possible, work must be carried out in the absence of voltage!
• Do not work at > 90 V DC!
• In the case of electrical cables/lines as part of an electrical installation/system work must always be carried out free of voltage!
• ET : The devices must be switched on before it is connected to cable/lines. Otherwise dangerous error states will not be detected immediately!

TONE Mode – Search via Tone Signal

Information on the Search Tone

• The ET has six search frequencies and two sound modes (ALT/SOLID). After switching on in TONE mode, the ET starts in ALTerning mode. Pressing the SOLID or ALT key briefly (< 2 s) toggles between the two modes and this is displayed through the LEDs to the right of the respective key. If the SOLID or ALT key is pressed for longer than 2 s, the search frequency is toggled. The respective clear LED lights up briefly to confirm the keystroke and the selection.
• With the ET 720/ET800, a short confirmation beep and then the selected frequency is also audible. To select the next frequency, release the key, and press it again for longer than 2 s. In SOLID mode it is possible to switch between 1 kHz, 1.9 kHz and 577.5 Hz.
• In SOLID, the frequencies can be switched between 1 kHz, 1,9 kHz, and 577,5 Hz. In ALT mode, the frequency combinations 880 Hz,1 kHz, 1.9 kHz, 2.6 kHz, and 577.5 pulses can be selected. The different frequencies can be used to distinguish the search devices.
• Ideally, the cables/lines/wires are voltage-free. However, the search signal can be fed into active (live but max. 90 V) telecommunication and data cables and lines without interference. ET400/ET720/ET800 are high-impedance for data signals, and thus it is possible to send search signals onto active telephone lines with ISDN and ADSL systems without data interference. The ET400 sends, contrary to the other ET, a sinusoidal signal instead of a square wave and also has an additional filter so that interference is reduced even further. Searching cables and lines
• To search for cables – also under plaster – and lines, the ET is connected to the earth (e.g. protective conductor, water line) with the black test lead and to a single wire or a pair of wires with the red test lead. When searching for shielded cables/lines, the red test lead is connected to the shield and the black one to earth. If there is no shield, two wires (no pair!) are connected to the cable line. If the screen is earthed, it must be disconnected on both sides. To find and trace a coax cable, the other end must be open. If this is connected to a distributor, it cannot be found due to the shielding of the coax cable.
• In the case of telecommunication or data cables/lines with twisted wires, these must not be connected together.
• Switch on the device. The selected tone is transmitted. Now select the search frequency. If there is a short-circuit, the sound is sent into the cable in a similar way to interrupted twin wires and all wires are charged with it but only up to a maximum of 200 meters. The cable/line is searched for with the Probe and can be followed contactless with the Probe from a distance of up to 60 cm away from the cable. The Probe is switched on by pressing and holding the LOW or HIGH key. To find a signal from a greater distance or a weak signal, press the HIGH key. In the case of large cable/line bundles at a distributor or in a platform, the Probe is moved flat over the bundle while pressing the HIGH button at the same time. Once the cable/line with the strongest signal have been determined, press the LOW key to define the cable you are looking for with millimeter precision. The highest signal level is always above the cable.

Searching Wire Pairs (Twin Wires)

• When searching for twin wires and discovering overloads, an ET test lead is connected to each core of a twin wire. In this case, it must be the twisted pair. This can be done automatically by plugging into a junction box or by connecting to the open cable end.
• Using the Probe and holding the HIGH button down, the pair is found at the other end or at each distributor. To find the exact pair with the strongest signal, the LOW button is pressed. If the pair is twisted over the whole distance, then the exact pair is found. If, for example, there is a wire break or an exchange of a single wire (split) on the route, several wires with the search signal are found at the distributor. This then indicates a cabling error: Now you have retrace back to narrow down the error. For open cable ends, the procedure is similar. The wires are fanned out and the Probe is moved evenly above them while pressing down the LOW button.
• If the test tip of the Probe is now led over the wires, a high level is displayed over the first wire of the correct wire pair, a minimum level in the middle, and a high level again over the second wire. This identifies the pair exactly. If no minimum can be found, it is either the wrong pair of wires or there is a cable fault, e.g. caused by an interruption, an exchange, or an overcurrent (what is called a split pair).
• The ET sends the search frequency with approx. 12 dB also into cables/lines with a terminating resistor down to 50 Ω. Thus with the ET, a search tone can also be sent to telephone or data lines carrying supply voltage. The maximum cable/line/wire length is 15 km (unloaded).

Mode CONT – Continuity and Resistance Testing
If the slide switch on the right side of the ET set to CONT, the continuity test mode is activated. A test voltage is applied to the test lead. This way, the continuity of cables, lines, contacts, wires, or resistors up to 100 kΩ can be tested easily. The green CONT LED flashes briefly when the test has been activated or when the resistance at the test terminals exceeds 100 kΩ. It lights up from bright to dark, depending on the value of the resistor. This allows an approximate determination of the resistance. In case of EDP cabling, determining whether the cable is patched is thus easy and interference-free. The ET720 and ET800 have an additional sound test mode built in. This replaces what is called a “beeper”. The frequency of the tone depends on the resistance. At 0 Ω (short circuit) approx. 3 kHz and at approx. 100 kΩ 500 Hz are audible. This makes it possible to estimate resistance values. But capacitors and other components can also be easily tested in this way. Fast display of line status For live data lines/cables (90 V max.). The ET is high- impedance (~10 MΩ). The cable/line therefore will not be loaded. The status of the connection cable, for example, is displayed immediately after switching on and plugging the ET into the connection socket. How the ET is connected depends on the device variant, e.g. directly with the RJ-11 plug, or with the optionally available TAE adapter or by simply connecting to the wires using the crocodile clips. Free line Supply voltage up to 90 Volt DC (ISDN). The LED POL lights up and its intensity depends on the voltage level. Red: a/b reversed; green: correctly polarized, A wire or minus on red terminal. The ET additionally indicates with a bright red POL LED that the voltage on the test leads exceeds 90 V. This information can also be used to identify the voltage at the ISDN U interface. Starting at 100 V,
ET720 and ET800 sound an alarm tone to warn of high voltage. Busy line Supply voltage between 10 and 20 V DC. LED POL glows darkly. Red: a/b reversed; green: correctly polarized. Useful e.g. at a distributor to check whether the line is busy or not. Alternating call voltage is indicated by the red and green POL LED lighting up. If the alternating voltage is AC only, the POL LED lights orange. In general, ET can be used to check any type of voltage source (max. 90 V) for polarity, to check the type of voltage and its approximate level.

Mode DATA – Network Port Test and Port Finder Function
(Link Blink Function) (ET400/ET720/ET800 only) If the slide switch is set to DATA position, the DATA LED lights up dimly green as an indication. The additional yellow RJ-45 test lead is used for testing. Plugged into a network port, the green DATA LED lights up brightly in sync with the normal link pulse signal (NLP) if the network port is patched. The NLP signal is transmitted every 4 seconds. This is indicated on the ET with a change in the blinking of the DATA LED and at the ET720/ET800 with a tone sequence. With the most common hubs, switches, or routers, the LINK LED belonging to the port is switched on and off in time with the signal2. This way, the port associated with the network socket can be identified.

Finding and Testing Fiber Optic (FO) Cables (ET800 only)
The fiber optic test uses a laser light source with visible red light. The transmitting power is less than 1 mW (laser class 2).

Warning : Never look directly into the laser beam!
The universal socket is suitable for all common plugs with 2.5 mm ferrule. It has a bronze spring so that the ferrule is held firmly in the socket to prevent accidental unplugging. The ceramic material protects the ferrule against metallic impurities.

If required, adapters are available from 2.5 mm to 1.25 mm (Z180A), from 2.5 mm to POF (Z180B) and from 2.5 mm to SMA 905 (Z180C).

Testing Procedure

1. Switch on the ET800 in TONE mode. Now plug the fiber optic cable with the ferrule into the universal socket. To switch on the laser source, press the SOLID and ALT keys together for > 1 s.
2. The ET800 confirms the LASER

In some cases, the NLP signal filtering must be deactivated in the settings of the hub/ router/switch. mode with a power-on sound and a flashing ALT LED. At first the unmodulated mode is active. The FO signal flashes and correspondingly the ALT LED 1 × per second. To switch to the equally unmodulated constant FO signal Continuous Wave (CW), press the SOLID key. To change to the modulated mode, press the ALT or SOLID key > 2 s, depending on which signal you want. In each mode, 3 possible tone sequences are available which can be activated by pressing the key again for > 2 s. The tone sequence will be audible on the integrated speaker once right after switching. In case that several fibers are to be distinguished, several ET800 can be used together but with different modes and in combination with suitable detection equipment connect to the end of the fibers. Independent of LASER mode, the laser light source can be used to detect small breaks in bad connections, strong bends and the end of the connected cable. The search distance is > 10 km, but depends on the fiber type.
