DIGI-7 The Digi-7 line locator is two locators built into one. Both receiver and transmitter will operate in a full automatic mode or a full manual mode with the push of a button. ACCESSORIES FOR THE MODEL DIGI-7 LINE LOCATOR The Model I.C.49, I,C,56, or I.C.56WT Inductive Couplers are used to help identify one line from other utilities even though they are sharing a common ground.
Automatic Mode In the automatic mode, the receiver operates with a minimal amount of input or interpretation from the operator. The operator simply follows the Left/Right guidance system. The operator can choose to display the locate information in either the Peak or Null modes depending on preference. The On-Off/Volume/Sensitivity Control is used only to adjust the loudspeaker volume in the automatic mode. While locating, the display provides three different pieces of information to the operator.
DEFINITION OF A NULL - See Fig. 6. A high signal reading is found on both sides of the conductor, and a loss of signal is found directly over the conductor. TRANSMITTER The Digi-7 transmitter has both INDUCTIVE and CONDUCTIVE methods to apply signal to the conductor to be traced. On the faceplate, two rocker switches are located in the upper right hand side. One switch turns the transmitter on and off. The second switch is used to operate in the Automatic or Manual mode.
OPERATING INSTRUCTIONS DEFINITION OF A PEAK: See Figure 5. A low signal reading is found on both sides of the conductor, and a high signal is found directly over the conductor. Direct Tracing With the direct output cable assembly plugged into the phone jack on the transmitter, connect the red clip to the line being traced and the black clip to the driven ground that is supplied with the instrument.
