User manual WHITES ELECTRONICS 5900DI PRO

[. . . ] NO-AUTO doesn't require motion to respond to targets. A Message from. . . White Congratulations, and thank you for choosing the 5900DI PRO. As an avid detectorist, I commend you for making an excellent choice in deep seeking equipment. White's continually strives to achieve performance and reliability above and beyond your expectations. [. . . ] The optimum setting is one which gives smooth operation allowing deep targets to be heard clearly, and GROUND BALANCE achieved with a reasonable degree of effort. If the instruments performance seems temperamental or unstable, a SIGNAL BALANCE setting slightly toward (-) should be selected. (8) Description of Controls continued. . . . . GROUND BALANCE ELIMINADOR DE TIERRA For the best results, the GROUND BALANCE control needs to be adjusted each time the detector is used. The NORMAL setting works well for most conditions. GROUND BALANCE is adjusted to cancel out or ignore common mineralization in the ground thus, allowing the deepest available penetration. A setting clockwise toward (+) is used for higher mineralization and a setting counterclockwise toward the (-) would be sufficient for low mineralized soils. The method for adjusting this control will be covered in the section on TUNING. In a nut shell, when GROUND BALANCE is set properly little or no change in THRESHOLD hum is noted as the detector is lifted slightly up or down in relationship to the ground. It should also be noted that the AUTOMATIC THRESHOLD control, which will be discussed in the next section, should be set in the NO-AUTO position while the GROUND BALANCE control is being adjusted. The GROUND BALANCE control and the SIGNAL BALANCE control work hand in hand to tune out undesired responses, and provide the deepest possible penetration (detection depth). (9) Description of Controls continued. . . . . AUTOMATIC THRESHOLD ZUMBIDO DE AUTOAJUSTO AUTO NO AUTO The AUTOMATIC THRESHOLD control is used to activate (AUTO), or disable (NO-AUTO), the automated threshold resetting feature. This feature offers automatic threshold maintenance. When AUTO is used it allows the threshold hum of the detector to remain smooth or constant regardless of small changes in the ground mineralization, or upward / downward drift of the electronic signal. 2) Turn the THRESHOLD clockwise and check the meter to determine conditions of battery pack (must be 75% or higher to operate the detector). The THRESHOLD control, at this point, needs to be readjusted for a very faint hum. The detector will operate well (locate metal) in most locations with the controls at these settings. However, for optimum performance and penetration depth, fine tuning of the GROUND BALANCE and SIGNAL BALANCE controls are necessary. GROUND BALANCE PROCEDURE 3) Set the AUTOMATIC THRESHOLD control to the NO-AUTO position. Note: Stay away from all metallic objects . Remove all significant metal from your body. . belt buckles, car keys, watches, knives, etc. Determine whether the sound increases or decreases when the detector is raised about six inches further above the ground and make the appropriate GROUND BALANCE correction. Lower the loop and press Once 5900DI PRO can be and release the PUSH BUTTON. lifted about six inches, Continue with this procedure until there with little or no change is little or no change in THRESHOLD in threshold, Ground when the DETECTOR is lifted. [. . . ] Store your detector indoors in a heated area during the winter months, with the batteries removed from the control box, and the batteries removed from the battery holder. 4) Care must be taken so that the front and or rear antennas are not bent during storage or use. These are precision parts, their function and performance are very much altered by physical shape and dimensions. 5) The battery holder requires some attention with time and use. [. . . ]
