Page 6: Absolute Signal Strength
800.336.9681 www.comsonics.com Absolute Signal Strength The Receiver provides the operator with a direct measurement of the Receiver’s signal strength. The measurement is displayed with three numerical digits (ex: 485) located at the top of the LCD display. The measurement range is from 0 to 999 indicating a very weak signal (0) to a very strong signal (999). -
Page 7: Direct Connection
800.336.9681 www.comsonics.com Direct Connection CAUTION CAUTION ALWAYS TURN TRANSMITTER BEFORE DO NOT CONNECT TO LIVE OR CONNECTING AND DISCONNECTING TEST LEADS ENERGIZED POWER CABLES Direct Connection is the most reliable method of signal application. This method is relatively free of interference. -
Page 8: Inductive Connection
800.336.9681 www.comsonics.com Inductive Connection This method is convenient to use, and services are not interrupted. No test cords or connections are needed. The cable or pipe must have good insulation or non-conductive coating, or the operating range will be short. -
Page 9: Selecting The Tracing Signal
800.336.9681 www.comsonics.com Selecting the Tracing Signal The choice of 815 Hz, 8 kHz, 33 kHz or 82 kHz Frequency is dependent on the conditions of the locate. The 815 Hz, 8 kHz, 33 kHz and 82 kHz signals each have their advantages. It is recommended to begin by using the 815 Hz signal, and continue as long as you are confident in the results. -
Page 10: Locating The Cable Or Pipe
800.336.9681 www.comsonics.com Locating the Cable or Pipe Make sure the Transmitter is connected and in the ON position. Then move approximately 15 feet (4.5 meters) away from the Transmitter along the path. (Move about 25 feet (7.5 meters) for the Inductive search mode.) -
Page 11: Peak Mode Locating Continued
800.336.9681 www.comsonics.com Peak Mode Locating Continued Trace the path by walking away from the Transmitter at a moderate pace. Move the Receiver to the left and right while walking, following the Peak indications. As you trace the path, the Peak meter reading may slowly fade as you move away from the Transmitter. -
Page 12: Absolute Signal Strength
The Receiver may also be detecting adjacent cables or is not directly over the target conductor. Verifying target conductor path precisely before measuring current again. If at anytime the display reads ‘CAL’, contact ComSonics Support. -
Page 13: Gain Change Indication
800.336.9681 www.comsonics.com Gain Change Indication The GAIN up and down buttons are used to increase and decrease the gain in small amounts. If the meter reading is very low, pressing the Gain up button will center the meter reading to mid-scale. -
Page 14: Depth Measurement 45º Angle Method
800.336.9681 www.comsonics.com Depth Measurement 45º Angle Method Move to the location you want to measure depth. Stay at least 15 feet away from the Transmitter. Move the Receiver left to right across the path until the cable is located. Mark the path on the ground as precisely as possible using the Null Method. -
Page 15: Fault Locating
800.336.9681 www.comsonics.com Fault Locating Fault locating determines the position of an insulated break on an underground conductor. In the case of an insulation fault, some of the signal will return to the Transmitter attached to the Ground Rod through a break in the insulation. -
Page 16: Ground Return Probe Insertion
800.336.9681 www.comsonics.com Ground Return Probe Insertion Circuitry between the ground spikes provides a path for current in the soil returning to the Ground Rod. The current enters one spike of the Ground Return Probe and exits the other spike. The GRP should be inserted into the soil with consistent force and depth. -
Page 17: Ground Return Probe Fault Locating
800.336.9681 www.comsonics.com Ground Return Probe Fault Locating Use 815 Hz when fault locating. As you walk the path using the GRP, drop the probe every three or four steps. As you near an area of high current concentration in the soil, the Ground Rod or the fault, the Receiver will record higher and higher readings. -
Page 18: Faults Beneath Paved Surfaces
800.336.9681 www.comsonics.com Faults Beneath Paved Surfaces A potential problem could exist if a fault should lie beneath a paved surface. In this case, the Ground Return Probe will be used in the dirt at the side of the paved area. Since the return current in the soil begins its return from the fault - like the spokes of a wheel laying on the ground - equal amounts of current will enter the GRP if it is placed on the ground and positioned broadside to the fault. -
