[. . . ] How to use it To ground balance Pulsescan TDI, the search coil is pumped slowly up and down from one inch near the ground to 6 or 8 inches above the ground while listening for a change in sound. This process must be done with the Target Conductivity control set to All. Start this process with the Gnd Bal Control set at 6 (12 O' clock). Begin pumping the coil slowly up and down toward the ground. You will hear the high tone of low-conductive metal as you approach the ground. Now start turning the Ground Balance knob slowly clockwise as you continue this pumping process. The high tone will usually continue with each pump toward the ground for a short period of time, and then start to fade to no tone other than the threshold hum. Continue the process of pumping slowly, and turning the knob clockwise past the quiet zone. You will begin to hear the low tone as you approach the ground. If the ground has moderate mineralization you may not hear the low tone. At this point, continue with the pumping process, but start to turn the ground balance knob back counter clockwise until you enter the quiet zone again. This area of quiet 4 PulseScan TDI Owner's Guide where you hear only the faint hum of the threshold is where the Pulsescan TDI is balanced to the ground. You will have to turn the knob very slowly in very small increments to reach the most exacting point for eliminating ground minerals. At this point, you will most likely notice that the Ground Balance knob is usually between 8 and 9 on the scale. If you change the setting on the Gain or the Pulse Delay, you should adjust the Ground Balance setting if needed. In addition, if you begin to hear ground noises (false signals) you should also adjust the ground balance. Of course, the Gnd Bal toggle must be On to use the Gnd Bal control. If the Pulsescan TDI does not require ground balancing, there is another option. The Pulsescan TDI can be operated as a standard pulse detector with no variable audio by switching the Gnd Bal toggle OFF. The upside of this is that the detector will detect deeper. If the Pulsescan does achieve ground balance, the Gnd Bal toggle must be kept On, and both Gnd Bal and the Variable Audio feature will be active. This situation indicates that there is enough iron mineralization to balance. PulseScan TDI Owner's Guide 5 INITIAL SET-UP - To get started, set the controls to a mid-range position.
