User manual WHITES ELECTRONICS 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 following instructions are intended to familiarize you with this fine detector, and give you a good understanding of the basics. Practice using your detector in the field, and study this manual carefully. [. . . ] If little interference is experienced and ground balancing can easily be achieved, the SIGNAL BALANCE control may be set slightly further clockwise toward (+). If the detector operates erratically, due to the use of too (+) a setting, the response from deeper targets will be obscured. Additionally, if the GROUND BALANCE can not be set correctly, the SIGNAL BALANCE is overloading the detectors receive signal, and will reduce detection depth. 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. 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. 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. D) The GROUND BALANCE procedure becomes critical as the SIGNAL BALANCE control is turned toward (+) . The SIGNAL BALANCE control need not be set past the NORMAL range for most searching. If GROUND BALANCE cannot be accomplished as set out above, try moving to a different location as you may be over a buried metal object. If trouble persists, turn SIGNAL BALANCE control slightly counterclockwise toward (-) and try again. The greatest detection depth (deepest penetration) will be achieved by a SIGNAL BALANCE setting suited for the conditions, indicated by smooth stable operation, and the ability to set the GROUND BALANCE control. If GROUND BALANCE is appropriate at NORMAL, or if finding the correct GROUND BALANCE setting is relatively easy, you may want to turn the SIGNAL BALANCE control slightly clockwise toward (+), and repeat the GROUND BALANCING steps. This assures the best SIGNAL BALANCE setting for the conditions, thus the greatest detection depth. The AUTOMATIC THRESHOLD should be returned to AUTO once GROUND BALANCE is completed. (14) Locating Metal The volume will increase and the meter will read higher when the instrument is passed over a buried metal object. [. . . ] The instrument should be cleaned after heavy use on or around a saltwater beach. The warranty does not cover cosmetic imperfections due to wear, or exposure to sun and salt air. When left in a car on a warm day, cover it to protect it from the direct sun. 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. [. . . ]
