Ⅲ) Refasten the battery cap. - Slit manufacturing dimensions
The portion of the boring head (drill) containing the transmitter has slits to allow the transmitter to transmit a magnetic field. For best results, ensure that slits are as indicated in the diagram below. Suggested dimensions. Please contact maker for details.
Operating the Locator
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
- Pitch angle unit selection
Pitch angle can be displayed either in degrees or as a gradient (percentage).
- 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.
- Selecting the transmitter
The transmitter has three available frequencies. Select the most suitable frequency for your jobsite.
For details, please refer to section 3) – “Measuring noise”.
- Depth Correction (Calibration)
Navigate to the calibration icon in the top right corner of the screen and press MODE to select.
For details, refer to section 2) – “Depth correction (Calibration)”.
Depth correction (Calibration)
- Set-up
From a position of 3m/10ft. from the boring head, place the locator as indicated in the diagram below.
- Starting calibration: Turn the locator ON and begin depth calibration
- When the calibration is finishes with no errors
・After receiving a display screen like the diagram to the left, return to standard measurement mode.
・The measurement value should be displayed as 2.82m/ 9ft.5in. : the initial 3m /
10ft. minus the distance from the ground to the coil (18cm / 7in.).
・When measuring a real drill under the ground, 3m / 10ft. will be displayed as 3.00m / 10ft.0 in.
- In the case of an error
An error message will be displayed when the signal cannot be received normally.
Please perform the following checks:
・Is the batteries in the transmitter
・That the batteries are aligned properly in the transmitter
・The transmitter selected on the locator matches the transmitter being used
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.
- Perform calibration as described in section 2) – Depth Correction (calibration)
- Remove the batteries from the transmitter so that there is no signal coming from it.
- Take a depth measurement.
Confirm the measured depth on the locator of the jobsite at which you will be using the unit.
- Calculate the transmission range of your site based on the measured depth.
Formula: Transmission range = Measured depth × 0.8
（e.g. for a measured depth of 30.0 m, the transmission range would be 24.0 m）
Features of each transmitter type
- HDDTRAK T38: Frequency – 38 kHz
When the noise level is good, this transmitter has the longest range. - HDDTRAK T9: Frequency – 9.5 kHz
This transmitter has the lowest frequency, making it less susceptible to interference from metal plating or other obstructions. - HDDTRAK T14: Frequency – 14.4 kHz
This is a more balanced, midrange transmitter.
Measuring position
There are two methods for measuring location, as indicated in the diagram below.
Scan method changes automatically based on the position of the Drill/Transmitter, as indicated in the diagram below.
Near distance mode (Detailed explanation)
- Direction of locator
In near distance mode ensure that
the locator is facing in the same direction as the drill is moving in.
- Measuring linear position (front/back)
- Measuring tilt (yaw angle)
- Measuring Lateral position (Left/Right)
Measure the point at which reception sensitivity (bar graph display) is at its peak.
- 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.
- 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.
b) Keep locator at consistent posture when moving it.
Avoid tilting or twisting of the locator as this can cause measurement errors.
long distance mode (Detailed explanation)
Long distance L/R scanning mode. Conduct scan as indicated in the diagram below (Top view).
