Locate Mode Screen
The first option in the main menu is Locate Mode, which displays the Locate Mode screen.
When the receiver is detecting a signal from a transmitter, the Locate Mode screen provides
real-time data about the transmitter’s location, temperature, pitch, roll, and signal strength.
Locate Mode Screen with Transmitter in Range (Trigger Released)
The roll/pitch update meter displays the quality of roll/pitch data
being received from the transmitter. When the meter is empty, no
roll/pitch data is being received, and none will appear on either
the receiver or the remote display. Depth and predicted depth
readings may still be taken, but the receiver will assume the
transmitter has a pitch of zero, as indicated by the image to the
right appearing on the depth or predicted depth mode screen.
When the roll offset function (an electronic compensation to
match the transmitter’s 12 o’clock position to the drill head’s
12 o’clock position) is enabled, the roll indicator will change to a
circle as shown at right. For more information on using roll offset,
see Set Roll Offset on page 11.
When the receiver is set to detect an F5 12 kHz transmitter and a
“12/1.3” dual-frequency transmitter (part number F5D 12/1.3 or
F5Dp 12/1.3) is being used in dual mode, the dual transmitter
symbol will appear to the upper left of the roll indicator as shown
at right. The letters “DL” or “DH” will accompany this symbol when
the receiver is set to detect the dual low (1.3 kHz) or dual high (12
kHz) frequency, respectively. For proper communication, set the
receiver to detect the dual mode transmitter as described in
Transmitter Selection on page xxxix.
