The KE701 Kit (EASYTEST720/PROBE410) improves speed and confidence in the installation and maintenance of wiring whether it is for power, telecommunication, alarm or control. EASYTEST720 can transmit either three continuous tracing tones (SOLID) or two alternating tones (ALT). The Solid or the Alt function is easily selected from the front panel using the ALT and SOLID buttons. An LED beside each button indicates the selected function. To start or stop the tone, first use the ON/OFF button then select the trace tone. The unit can be connected to send the trace tone to any kind of cable, including a live telephone line. The unit is protected to 400 Vac in TONE mode and up to 240 Vac in CONT mode. EASYTEST720 provides durable alligator clips and snag-proof modular plugs for both RJ11 and RJ45 with strain relief for reliability. The special RJ11 modular plug has protection slots for pins 1 and 8 that will fit RJ45 jacks without damaging them. If the RJ45 plug is inserted into an active LAN jack in the DATA mode, the DATA LED will pulse brightly, and the associated link activity light on the conventional LAN hub or switch will begin to blink. In the CONT position EASYTEST720 leads and RJ11 plug will indicate short circuits (zero ohms to 100KOhm). When switched off EASYTEST720 will indicate the status of a connected telephone line including: service voltage presence and polarity, idle line, busy line, and incoming ringing. The capacitive PROBE410 (U.S. PROBE310) is highly sensitive and works well with EASYTEST720 or any other tone generator to identify and trace wires or cables. The two-position HIGH and LOW volume switch is constructed with a highly dust and moisture resistant mylar membrane for easy, reliable operation. With the HIGH button depressed the PROBE410 can detect a traced cable at lateral distances of up to 100 cm. A more precise location of specific wires is usually
