Aines Model 140B/MCIn good working condition Includes 9 Volt battery 40B/MC WeathertiteTone Test Set Instruction Manual . Descriptions and Use. 1. General. 1.01 This section covers the description and use of the Aines Manufacturing Corp.Model 140B/MC Tone Test Set. 2. Description. 2.01 The Model 140B/MC Tone Test Set is encased in a heavy-duty plastic weathertite/waterresistant orange case. The 140B/MC is equipped with: 1. Tone-Off-Continuity switch. 2. Three (3) color LED (light emitting diode). 3. Two nylon braided cords consisting of tinsel conductors with PVC insulation and an outer nylon braid with an overall length of fourteen (14) inches. 4. Each cord is equipped with the Aines 6A Test Clip and a red or black insulating boot. The 6P clip is an option. 5. Two conductor modular cord (Aines "K" Plug). 6. Five (5) inch nylon loop lanyard attached to rear cover. 2.02 The 140B/MC Tone Test Set uses integrated circuitry and has dual tone capability. Alternating tone at 520-1010 Hz+/-3% or steady tone at 1010 Hz +/-3%. 2.03 The following tests can be performed when using the 140B/MC Tone Test Set: 1. Tracing cable pairs. 2. Locate wires or cables in walls when used with either the Aines 150SP Stationman Probe, the 250SSP Speaker Probe or the 400NR StationMaster noise resistant probe. 3. Provide talk battery on dead pairs. 4. Check for shorts, crosses or grounds. 5. Continuity tests. 6. Checks for AC on line (FEMF). 7. Line condition identification: A. Clear Line B. Busy Line C. Ringing Line 8. Positive line verification. 2.04 The 140B/MC Tone Test Set can be used on solid state circuits as no DC voltage or high AC signal voltage is emitted out on the line in the tone position. NOTE: When the 140B/MC Tone Test Set is used in the tone position, NO AUDIBLE TONE WILL BE HEARD. You must use one of the following probes to hear tone: 1. 150SP Stationman Probe with Lineman's test set (butt set). 2. 250SSP Stationman Speaker Probe. 3. 400NR StationMaster Probe (noise resistant speaker probe). 2.05 Before using the 140B/MC Tone Test Set, check to make sure the battery is good. This can be accomplished by by putting the switch in the continuity position and touching the two 6A clips together. The LED will light up GREEN if the battery is good. 3. Polarity Test Function. 3.01 "OFF" position of the function switch (centered) In the OFF position of the function switch, the 140B/MC Tone Test Set checks the polarity and condition of a telephone line. 3.02 When the RED test lead is connected to the RING side of the circuit and the BLACK lead is connected to the TIP side of the circuit, the LED will light upGREEN showing NORMAL polarity. If the leads are reversed, the LED will light upRED indicating REVERSE polarity. 3.03 Similarly, when the modular plug is connected to a modular telephone jack, GREEN indicates NORMAL polarity and RED indicates REVERSE polarity. 3.04 The LED will light up YELLOW if there is AC on the line. 3.05 The 140B/MC, while in the OFF position, may be used to detect ringing voltage on the line. When ringing voltage is present, the LED will show a flashingYELLOW light. 4. Continuity Test Function. 4.01 "CONT" position of the function switch (towards the LED) the 140B/MC Tone Test Set can be used to check for continuity of a telephone line or other circuit. 4.02 When the clip leads are connected to the circuit, the LED will glowGREEN if there is continuity through the circuit. 4.03 The brightness of the LED indicated how much resistance is in the circuit. Zero resistance is a short circuit and results in the greatest brightness. There will be noticeable light output even for circuit resistance as much as ten thousand ohms. 4.04 The Model 140B/MC may also be used in the CONT position to supply talk power to a telephone line. It will provide about 2.5 volts to a six hundred ohm line. 5. Tone Generator Function. 5.01 "TONE" position of the function switch (opposite the LED) the 140B/MC serves as a tone generator in inject signal into a telephone line which may be used for pair tracing. 5.02 Two different tones, a steady tone or an alternating tone may be selected by the small slide switch on the printed circuit board near the battery. The slide switch is accessible by removing the back cover. 5.03 In the steady position (switch to the right), a steady tone of 1010 hertz +/-3% is generated. 5.04 In the alternating position (switch to the left), a 520Hz - 1010 Hz +/-3% alternating tone is generated. The switching rate is 2 cycles per second. CAUTION: Never connect the 140B/MC Tone Test Set to a live AC circuit! Shock or serious injury may result. An iso-insulator device is available for tracing live AC circuits using tone. Check with your supplier. 6. Battery Replacement. 6.01 A standard 9V battery or a 9V alkaline battery may be used. The battery may be easily replaced by unscrewing the captive screw on the back cover.
