830R/T Operator’s Manual Overview - 3 Intended Use Intended Use The 830R receiver is designed to locate buried pipes and cables at an 83.0775 kHz frequency. Optional passive power and cathodic protection frequencies (60, 120, and 180 Hz in North America; 50, 100, and 150 Hz in other locations) are available. The 830T transmitter places a single 83.0775 kHz signal on a target cable to be detected by an 830R receiver.

830R/T Operator’s Manual Locate - 32 Passive Location Passive Location Setup Follow setup procedures for the type of locating you will be doing. Always check receiver battery level at startup. NOTICE: Cables with no A/C current flowing through them are hard to detect and may be hazardous because they may still have voltage potential. To locate, turn on an appliance to cause current to flow and use active search methods.
830R/T Operator’s Manual Locate - 33 Passive Location Focus the Signal Move receiver over detected signal and rotate to find best signal response. Best signal indicates cable direction. Trace the Cable Walk along the suspected path while moving the receiver from side to side across the area.

830R/T Operator’s Manual Locating Concepts - 36 Signal Type Signal Type The 830R can detect two types of signals: • Active signals that are placed on a target cable with a transmitter. • Passive signals that reside on the target cable. Active There are three ways to place active signals on a target cable with a transmitter: • Direct connection (preferred method) requires a connection to be made directly onto target cable.
830R/T Operator’s Manual Locating Concepts - 37 Mode Mode Receiver The 830R receiver has two available modes. Mode Description Left/Right Allows receiver to trace cables that have had an 83.0775 kHz signal placed on them by a transmitter. Notes si0009c-d.eps Power Allows receiver to trace live power cables. 60 c00ic105t.eps IMPORTANT: Current must be flowing through the cable. In North America, available frequencies are: 60, 120, and 180 Hz.
830R/T Operator’s Manual Locating Concepts - 38 Mode Transmitter The 830T receiver has two operating modes and two troubleshooting indicators. Operating Mode Description Induction (broadcast) Signal is broadcast onto target line using antenna. Notes c00ic102t.eps Direct Connect or Inductive Clamp Signal is placed on target line through direct connect leads or inductive clamps. Indicates a closed circuit with good current flowing in the line. c00ic103t.
830R/T Operator’s Manual Locating Concepts - 39 Receiver Gain Level Receiver Gain Level In left/right mode, the receiver uses automatic gain control and requires no user adjustment. In optional power mode, the user adjusts the receiver gain setting. Action Result Effect increasing gain more sensitive to signal allows location farther away from signal source decreasing gain less sensitive to signal stabilizes signal Frequency The 830R/T system operates at a single active frequency: 83.0775 kHz.
830R/T Operator’s Manual Locating Concepts - 40 Common Signal Problems Common Signal Problems IMPORTANT: If target depth and location are critical, confirm by hand-digging or vacuum excavation. Distortion Distortion often happens when a metallic object partially distorts the signal, or a signal from a parallel cable interferes with target signal. False Signals False signals describe situations where the receiver indicates a cable location where there is no cable.
830R/T Operator’s Manual Locating Concepts - 41 Common Signal Problems Parallel Cables (Diverging Arrows in Left/Right Mode) A B C e16om019t.eps In situations where another cable (C) runs parallel to the target cable (A), the high frequency signal will couple to the other cable. This will allow the user to locate both cables in left/right mode and will create a false cable (B) between them. When locating the false cable, note that the arrows will not indicate the correct direction to the false cable.
