DigiTrak F2 Calibration

Always calibrate your DigiTrak Falcon F2 prior to initial use, when switching to a new transmitter, receiver, drill head, or optimized transmitter band. However, if you are switching between bands on a transmitter that have already been paired and calibrated, recalibration is not needed. Utilize the Calibration menu for DigiTrak F2 calibration and confirm the Above Ground Range. The calibration process works the same on DigiTrak F2 Classic, DigiTrak Falcon F2 and F2+.

1-Point Calibration

Depth readings can be calibrated above ground before initiating the drilling process using a one-point calibration method.

For DigiTrak F2 Calibration, follow these steps:

1. Position the receiver and the transmitter (installed in a drill head) side by side on level ground, ensuring both devices are powered on.

1. On the receiver's Locate screen, confirm that roll and pitch values are visible, and a stable signal is being received from the transmitter. The transmitter's signal strength during calibration can be found on the second page of the Settings menu. Any sudden signal strength changes within a 10 ft. distance may indicate interference or equipment issues.
2. Bring the locator within 2 ft. proximity to the transmitter, causing signal attenuation, indicated by the appearance of an A symbol at the bottom left of the roll indicator. Move the locator back to a 10 ft. distance and verify that the attenuation symbol disappears. If the symbol persists, it suggests the presence of excessive noise.
3. From the Main menu, navigate to Calibration and select 1PT CAL (1-point calibration).

1. Verify that the distance from the center of the transmitter to the inside edge of the receiver measures 10 ft. You can use a tape measure for accuracy. Once confirmed, click to initiate the calibration process. Note: If you delay clicking the trigger for more than approximately 15 seconds, the calibration will terminate, and the Above Ground Range (AGR) screen will appear (refer to the next section).
2. The display will count down to zero while the receiver records the calibration point. It is important not to move the receiver during this process.
3. A successful calibration is indicated by a check mark displayed above the transmitter icon along with four beeps. In the event of an unsuccessful calibration, an X symbol will appear above the transmitter icon accompanied by two beeps.

Reasons for unsuccessful calibration:

Calibration will not be successful if the signal strength from the transmitter falls below 300 points or exceeds 950 points. The symbol "DOWN" indicates low signal strength, while "UP" indicates high or excessive signal strength. Additionally, calibration will fail if there is extreme signal attenuation indicated by the symbol "A"

Avoid calibrating under the following circumstances:

• If you are within 10 ft. of metal structures like steel pipes, chain-link fences, metal sidings, construction equipment, or automobiles.

• If the receiver is positioned above rebar or underground utilities.

• If the roll indicator on the locating screen displays an "A" at the bottom left, indicating signal attenuation caused by excessive interference. If feasible, relocate to a less noisy area before proceeding with the calibration.

• Calibration should not be performed when the receiver is surrounded by significant interference, which can be identified by observing high background noise readings on the frequency optimizer graph or a flashing signal strength value on the locate screen accompanied by the A icon.
• Transmitter data is not being displayed on the receiver.
• If the signal strength from the transmitter is below 300 points (too low) or above 950 points (too high), a calibration failure screen will appear, indicating either low or high signal strength.
• When calibrating, it is essential to have the transmitter installed in a drill head. Additionally, during the calibration process, the Height-Above-Ground (HAG) feature will be automatically disabled. After completing the calibration, it is necessary to manually re-enable the HAG feature.

Optional 50 Foot Calibration:

The 50 Foot Calibration feature is mainly intended for above-ground demonstrations of the guidance system and is not essential for drilling purposes. When measuring distances beyond 40 ft. above the ground, there can be variations in ground conditions that may cause readings to appear shallower or shorter than they actually are. This calibration feature is designed to adjust these measurements and account for such variations. The procedure for using this feature is quite similar to the one described for the 1-point calibration.
