DIGITAL CONTROL INCORPORATED
Glossary
Active Transmitter
A transmitter that has batteries installed or a cable transmitter that is hooked up to power.
Battery Charger
Used to charge and condition (discharge) the DigiTrak batteries. May be used with AC or DC sources
and is easily adapted for worldwide usage.
Cable Transmitter
Transmitter that is hard wired directly to the remote display unit and allows information to be obtained
during very long and/or deep drilling runs.
Clicking vs. Holding Trigger
See Trigger Clicked, Trigger In, and Trigger Out.
DataLog System
The logging function hardware and firmware used for collecting the data about the drilling operation to
produce plots of the borepath location.
Depth vs. Slant Distance vs. Range
Depth is the number displayed in the bottom window when the receiver is positioned directly above
the transmitter (with the trigger released). Slant distance is the number in the bottom window when
the receiver is not positioned above the transmitter (with the trigger released). Range is the maximum
depth of a transmitter; it can be affected by interference from both above- and below-ground sources,
conductive soil, and salt water.
Drill Head or Tool
See Housing.
English Mode
The term used to describe depth measurements in inches.
Firmware
The software and hardware configuration programmed in the equipment as provided by the manu-
facturer. The firmware is not accessible to the user and can only be upgraded by the manufacturer.
Four Turn Technique
An alternative method for finding the FNLP or the RNLP using the plus/minus (“+/–”) indicators.
Usually performed when the transmitter’s position is unknown. See “Four Turn Technique” in the
Locating Section.
Front Negative Locate Point (FNLP) = Locate Point in Front of Transmitter
This location, used in conjunction with the positive locate line (above the transmitter) and the rear
negative locate point, provides the transmitter’s location information to the operator. For more infor-
mation see the Locating Section.
Height-Above-Ground Distance = Ultrasonic Distance = Ultrasonic Measurement
The height-above-ground or ultrasonic distance is used by the receiver to calculate the depth/distance
of the transmitter. For more information see “Ultrasonic Function” in the Receiver Section.
