Page 4: Section I: Operating Modes
SECTION I: OPERATING MODES Pipe and cable locators in general can operate in a variety of modes and frequencies. The following is a brief description of the basic operating modes supported by the XTpc line of pipe and cable locators, and it is not intended to be a comprehensive locating tutorial. For additional information on pipe and cable locating theory and techniques, refer to Schonstedt’s training section online at www.schonstedt.com. Passive 50/60 Hz (P) In the passive mode, the transmitter is not used at all. Instead, the receiver searches for an appropriate harmonic of 60 or 50 Hz signals (factory preset). These signals are typically present in energized ... -
Page 5: Inductive (I)
Inductive (I) In the inductive mode, the transmitter imposes a signal of the "active" frequency onto the pipe or cable to be traced. It does so by radiating a signal through the inductive antenna, which is placed on the ground in a direction perpendicular to the pipe or cable being traced. The inductive antenna then induces a current onto the pipe or cable. In this mode, it is not necessary to provide a return path for the induced current to the transmitter. The induced current will travel on the pipe or cable for a distance making it possible to trace it. ... -

Page 8: Depth Measurement
Depth Measurement XTpc receivers have the ability to measure the approximate depth of the target pipe or cable being traced. The bottom tip of the receiver must touch the ground when depth measurement is made, and best results are obtained when the receiver is in a fully extended position. Depth measurements should only be made when the directional indication says that the target is directly below the receiver and the signal strength is adequate. Special considerations are required for the Sonde mode (see SECTION VIII: OPERATING RECOMMENDATIONS for details). Automatic and Manual Output Power The transmitters of the XTpc line of pipe and cable locators deliver power to the "load" connected to ... -

Page 10: Section Iii: Operating Controls
SECTION III: OPERATING CONTROLS The product controls are designed to be intuitive and require a minimum of training for effective use. The receiver can easily be operated with one hand. The transmitter automatically recognizes which accessory is plugged in, requiring no adjustments in the inductive and inductive clamp modes. Receiver A) All Models: ON/VOLUME ‐ This switch powers on the receiver and automatically sets the volume to High. Additional depressions of this switch will cycle the volume through Off (no sound), Medium, and High settings. OFF ‐ This switch removes power from the receiver. UP/DOWN Arrows ‐ When the receiver is operating in manual gain mode, pressing the UP or DOWN arrows will increase or decrease the gain from its current setting. When the receiver is operating in the automatic gain mode, the first press of the UP or DOWN arrow will switch the receiver to the manual gain mode. ... -

B) All models EXCLUDING XTpc+ : PASSIVE ‐ If the receiver is not operating in passive mode, pressing this switch will cause the receiver to go to the passive mode of operation. If the receiver is already operating in passive mode, pressing this switch will cause the receiver to stop the passive mode of operation. PC ‐ If the passive cathodic mode is available and the receiver is not operating in passive cathodic mode, pressing this switch will cause the receiver to go to the passive cathodic mode of operation. If the receiver is already operating in passive cathodic mode, pressing this switch will cause the receiver to stop the passive cathodic mode of operation. C) XTpc+ model ONLY: ... - Page 12 OUTPUT POWER ‐ This switch is used to manually select the output power in the conductive mode only. It has no use in the inductive and inductive clamp modes, where the output power is internally fixed. Each press increases the output power as follows: P‐L (1/2 watt) >> P‐1 (1 watt) >> P‐2 (2 watts) >> P‐5 (5 watts) >> P‐L (1/2 watt), and so on. At the 82 kHz operating frequency, only 1/2 and 1 watt are available (due to FCC regulations). ...

ALPHANUMERIC DISPLAY ‐ The alphanumeric display is used to display signal strength and depth. On XTpc+ models, the numeric display is also used for temporary indications of certain operating modes, frequencies (see table on page 14), and other brief information messages. Signal Strength ‐ This is an indication of the relative signal level detected by the receiver and is a function of the gain setting. Good signal strength will typically be between 200 and 800. The display range for signal strength is 0 to 999; however, a very high signal strength is not necessarily better. If readings of 995 or higher are consistent, the signal is too strong and steps should be taken to reduce it. If a reading of “OL” is observed, a signal is present which interferes with the signal the receiver is set to detect. Steps should be taken to identify the source of interference or to change the locating mode. ... - Page 16 BATTERY INDICATOR ‐ The "Battery" symbol indicates the transmitter's battery status. When all 3 segments inside the battery symbol are present, the battery is fully charged. When only the 2 bottom segments are present, the battery has a medium charge. When only the bottom segment is present, the battery has a low charge and should be recharged as soon as possible. If there are no segments present, the battery is extremely low and it should be recharged immediately. If the battery reaches a voltage dangerously close to the level when continuous operation can damage it, the empty battery ...

When replacing the battery, look at the inside of the battery door for the proper battery orientation. As a safety measure the unit will not turn on if the battery is not inserted correctly. You should never have to force the battery door closed. If the battery does not seem to be going in all the way, remove the ... -
Page 22: Battery Charger Indicators
The vehicle power supply, included with all XTpc models except the XTpc+, allows the battery to be recharged while driving from job to job. For the XTpc+ transmitter (the Tx5) an alternative for in‐ vehicle charging is to plug the AC power supply into one of the many commercially available vehicle DC‐to‐AC inverters capable of supplying at least 100 W of power. Battery Charger Indicators A) All transmitters EXCLUDING the XTpc+ (Tx5): After plugging the charger into the XTpc transmitter and connecting the AC power to it, allow a few minutes for it to settle. The LED indicators are as follows: FULL (Green): The charger has determined that the battery is fully charged CHARGING (Yellow): The charger is charging the battery FAULT (Red): See explanation below Conditions Under Which the FAULT LED Will Come On: The FAULT LED indicates that the battery charger is not charging the battery successfully. This can be for a number of reasons: the battery may be overcharged, the battery may not be taking a charge in a reasonable amount of time, the battery may be too warm to be charged without causing damage to its internal cells, or the battery charger may have an internal fault. ... -

B) XTpc+ ONLY (the Tx5 transmitter): When the Tx5 transmitter detects that the battery charger is plugged in, and if the power is turned ON, it will display “bAt CHA” on the LCD and the bars inside the battery indicator will “roll”. When the battery is fully charged, it will display “bAt FUL” on the LCD, as shown below. If the power is OFF, the battery will still charge, but no indication of charging activity or battery status will be shown on the LCD. If the battery charger is not charging the battery successfully, the following indication will be shown on the LCD: This can be for a number of reasons: the battery may be overcharged, the battery may not be taking a charge in a reasonable amount of time, the battery may be too warm to be charged without causing damage to its internal cells, or the battery charger may have an internal fault. ... - Page 24 Before normal charging can begin, the battery pack temperature and voltage must fall within predetermined acceptable limits. The temperature must be between 50° and 104° F (10° and 40° C). When the charger detects that these two conditions are not met, it will continue to “trickle charge” until the two conditions are met. Then, it will start normal charging. If the battery if faulty and it never reaches acceptable voltage to start normal charging, the charger continues to trickle charge. In this case, only a small fraction of full charge will be reached after the normal 4‐hours of charging time. If the charger is charging the battery in normal charge mode and the temperature rises above 140° F (60° C) before the battery is fully charged, the charger will switch to trickle charge mode. In this case, full charge may not be achieved after the normal 4‐hours of charging time. The battery pack also contains a thermostat that will open the circuit for safety if it gets too hot. ...

Page 28: Section Viii: Operating Recommendations
SECTION VIII: OPERATING RECOMMENDATIONS Follow these tips and recommendations to operate your XTpc Pipe and Cable Locator: 1) Whenever possible, use the conductive mode. It provides the strongest and best‐coupled signal. 2) When operating in conductive mode: The ground stake should be buried on a line perpendicular to the utility to be traced and as far from it as possible. Verify that a good circuit has been established by checking the output current from the transmitter. If necessary, make adjustments to the ground stake or clips to improve the connection. You can also manually adjust the output power to affect the output current. 3) When operating in the inductive mode, place the antenna (an additional accessory for the XTpc model but is built into the transmitter of the XTpc+ model) over the buried cable or pipe in the direction indicated by the label. (This application does not apply to XT‐512, which is a receiver only device.) ... - Page 29 Figure 1: Showing receiver orientation Figure 2: Showing receiver orientation in in “NULL” or lowest signal strength “Peak” ...
