Ⅱ) Insert two “C” type alkaline batteries, making sure the batteries are in the proper direction. + − + Ⅲ) Refasten the battery cap.
4. Operating the Locator 1) Settings Before use, it is necessary to adjust settings and perform depth calibration. Pressing the MODE button from the measurement screen will bring up the settings screen. (indicated in the diagram below) Navigate the menu by pressing the GAIN (▲) and L/R (▼) button. (The current selected setting will appear in red) To make your selection, Press the MODE button.
Ⅱ) Selecting a wireless channel Set the locator and the monitor to the same wireless channel. ※The minus mark [-] as indicated in the figure below means that the transmission is off. In the case of poor reception quality or interference, please change to a different channel. a) Navigate to the wireless icon in the menu and press MODE button to select. b) Toggle between channels using the GAIN (▲) and L/R (▼) button. c) Press MODE again and return to the measurement screen.
2) Depth correction (Calibration) Ⅰ) Set-up From a position of 3m/10ft. from the boring head, place the locator as indicated in the diagram below. a) Insert the transmitter inside the boring head 3 m/10 ft. b) Place the boring head so that the axis of the locator and the axis of the boring head are parallel to each other Ⅱ) Starting calibration: Turn the locator ON and begin depth calibration. a) Select “Calibration” from the menu and press and hold MODE for 1 second. b) Press the GAIN (▲) button.
3) Measuring noise As the levels of outside noise varies between job sites, the range of transmission will change. For this reason, it is useful to take a reading of the noise level of the jobsite before beginning. Ⅰ) Perform calibration as described in section 2) - Depth Correction (calibration) Ⅱ) Remove the batteries from the transmitter so that there is no signal coming from it. Ⅲ) Take a depth measurement. Confirm the measured depth on the locator of the jobsite at which you will be using the unit.
4) Measuring position There are two methods for measuring location, as indicated in the diagram below. a) Near distance mode b) Long distance mode (L/R position) 0 9999 0.65m 0.65m 12:00 2.5% 30°C 2.5% 30°C -T38- 12:00 -T38- Scan method changes automatically based on the position of the Drill/Transmitter, as indicated in the diagram below. In front of transmitter Behind transmitter Red circle Red circle Drill direction Button Icon is displayed.
5) Near distance mode (Detailed explanation) Ⅰ) Direction of locator In near distance mode ensure that the locator is facing in the same direction as the drill is moving in. NOTE: If locator is facing the opposite direction, position errors related to pitch angle cannot be corrected properly.
Ⅴ) Adjusting sensitivity When sensitivity is too low, or display shows 9999, press the GAIN (▲) button. Sensitivity will be adjusted automatically. ※When adjusting sensitivity, displayed value is relative value of 9000. Sensitivity is too low 7000 9000 Sensitivity is too high After 9999 adjustment Ⅵ) Position measurement precautions a) When moving the locator, ensure the height from the ground remains the same. Failure to do so can result in measurement errors.
6) long distance mode (Detailed explanation) Long distance L/R scanning mode. Conduct scan as indicated in the diagram below (Top view). Drill Drill is to the right of the locator Drill is to the left of the locator Change in L/R position decreases as distance from drill increase. *Depth will change to distance from drill to locator.
