® Receiver respectively). If there is an orange arrow below the serial number, then it is a remote receiver, and it is capable of sending a signal to a remote display unit at the drill.
Receiver ® The depth measurement units (centimeters or inches) and remote c ha n ne l s e tt i n g c an be c ha n ge d only during start-up (see “Chan ging Depth M easurement Units” and “Changing the Cha nnel Setting” below).
® Receiver For receivers that have pre-5.0 series firmware, the bottom window w ill continue to display the receiver’s distance from the tran smitter in the bottom windo w, not the predicted depth. (For more information, see “5.0 Series Firmware Functions” in this section or see the Locating Section.
Receiver ® Changing the Depth Measurement Units (English vs. Metric) The DigiTrak Receiver is capable of displayin g depth in either inches (English ) or centimeters (metric). The depth measurement units ca n onl y be changed during the start-up process.
® Receiver Warning Tones for Transmitter Overheat Beginning with firmware version 3.76, the DigiTrak Re ceiver will emit a series of increasing warning tones to signal transmitter overheating as follows: Temperature Range Warning Signal 14 ° C and below No audio or v isual warnings.
Receiver ® Following are some gene ral points regarding the ultrasoni c fun ction: ¾ The ultrasonic function in the receiver is independent of the transmi tter receiving functions. ¾ A single click to activate the ultrasonic func tion can be used an unlimited n umber of times without affecting the receiver’s calibration.
® Receiver Calibrating the Receiver There are two different calibration methods: 1 -point and 2-point. The 1-point calib ration is performed with the transmitter in the housing parallel to and 10 ft 5 in. (3.18 m) from the receiver, as described below.
Receiver ® 4. Click the trigger one time. 5. The receiver will beep. During the beep, pull in the trigger and hold it. 6. Continue to hold the trigger and watch the countdow n (from 5 to 0) displayed in the bottom window. This countdown is ac comp anied by a chirping sound.
® Receiver 5. During the tone, click the trigger again and contin ue to hold the receiver level and steady. You will then hear 2 beeps followed by a long 6-seco nd tone, i ndicating that the first calibration point is found.
Receiver ® Calibrating with Transmi tter Underground at Shallow Depth (< 10 fe et) Should recalibration be ne cessary when the transmitt er is below ground at depths less than 10 ft (3 m), it is possible to con duct a modified 1-point calibration proce dure.
® Receiver Finding Firmware Version It is possible to determine the firmware versi on in the re ceiver. This information is necessary to com plete troubleshooting diagno stics with DCI Customer Service by telephone. At start-up the firmware versio n is displayed briefly in the top left window.
Receiver ® Procedure for Observin g the Pre dict ed Depth When the receiver (with 5.0 firmware ) is at the FNLP and held level with the trigger in, the bottom win dow will rapidly flash the predicted.
® D IGITAL C ONTROL I NCORPORATED T ransmitter Fro nt Back Bat ter ies Ante nna Index Slot DigiTrak Transmitter A transmitter (also referred to as a so nde, beacon, or probe) is a device that emits electromagnetic signals at radio frequ encies and fits inside the tool ho using.
Transmitter ® Transmitter roll positions are displaye d digitally as a whole number from 1 through 12 in the top right window with the receiver’s trigger released. The num bers correspond to the hour han d of a cl ock. At the 12 o’clock position, the transmitter is oriented with the index sl ot at the top.
® Transmitter The temp dot should be white if the transmitter has not been exposed to excessive he at. If the temp dot is silver or gray, it indicates the transmi tter has been exposed to heat but not in exce ss of the speci- fications. A black temp dot indicates t he transmi tter has been e xposed to temperatures in excess of 104°C (220°F).
Transmitter ® any free space bet ween the transmitter and the side walls of the housing. If necessary, fabricate an “insert” behind the t ransmitter to ensure a snug fit. When wrapping with tape, be sure that the pitch will not be offset. If more tape is on one end than the other, th e trans- mitter will not be level in the housing.
® Transmitter Locating the Transmitter The properties of the transmitter’s m agnetic field enable the receiv er to locate the transmitter accurately below ground. The transmitter emit s an elliptically shaped field that allows the receiver to lo cate the transmitter using three specific location s, not just the highest sig nal.
Transmitter ® Serial Numbers All transmitters are identified by a serial number stamped in the metal battery compartment near the plastic/stainless steel conta ct.

® D IGITAL C ONTROL I NCORPORATED System Operating Instructions Start-up Procedure 1. Ensure that the transmitter has fresh C-cell alkaline batteries in stalled and place the transmitter inside the tool housing. 2. Click the receiver trigger, locate d under the han dle.
System Operation ® Optimal Operating Temperatures The minimum operating temperature for the DigiT rak locating equipment i s -4°F (-20°C). All battery- operated equipment is prone to “capa city loss” in cold temperatures. Excessively cold temp eratures can result in slow display response and increa sed m easurement errors.
® D IGITAL C ONTROL I NCORPORATED Signal Interference Before drilling (preferably before bidd ing on a project) the in terference potential at your site(s) should be evaluated. Interference ca n reduce the transmitter’s range or cause variable rea dings and possibly result in job slowdowns.
Signal Interference ® There are two steps to the electrical i nterference/b ackground noise ch eck. The first step takes one person; the second step requires two p eople. 1. With the transmitter off, test the amount of noise the receiver hears by holding in the trigger and walking the borepath from the laun ch to the exit location.
® D IGITAL C ONTROL I NCORPORATED Operational T ests Self-Test for Mark III Receivers Mark III Receivers have the capability of completing a diagnosti c self-tes t to confirm proper operation. This test must be conducted without a transmitter and in an interfe rence-free environment.
Operational Tests ® 3. Walk toward the axis line and wat ch for the plus (“+”) sign in the top left window to change to a minus (“–”) sign. Note this location. 4. Continue past the axis line, then stop and turn the receiver 180° around so it is facing in the opposite direction.
® Operational Tests ¾ Defective Transmitter – With the transmitter an d receiver on, place the transmitter against the receiver (long side of tran smitter parallel to long si de of receiver) while holding in the trig ger.
Operational Tests ® ¾ Battery Life – Verify the housing slot s (windows) are prop erly aligned over the transmitter’s antenna. If the battery life of a transmitter seems to be shorter than that noted in the spe cifications provided in the Transmitter Section, it could be due to battery arcing, which can occur in hard drilling conditions.
® Operational Tests Transmitter Battery Tests ¾ The design of the windows/slots in a h ousing can grea t ly affect the transmitter’ s battery life, especially on the red long-range DX Transmitters.

Locating ® Rec eiver par allel to Tran smitter and faci ng in oppo site direct i on Rec eiver p arallel to T r ansmi tter and facing i n sam e di r ect io n Receiver Can Face in Either Direction with Respect to Transmitter Handling the Receiver For the most accurate locating, the receiver m ust be held level and parallel to the transmitte r.
® Locating In summary, the three locations mentio ned above are as follows: the rear negative locate point (RNLP), behind the transmitter; the positive locate line, above the transmitter; and the front negative locate p oint (FNLP), ahead of the transmitter.
Locating ® PLL Drill Plu s Changes to Minus 2. To determine the la teral and therefore the actual location of the RNLP, turn toward the left so that the receiver is perp endicular (90 ° ) to the drill string and move the receiver forward.
® Locating Finding the Front Negative Locate Point (FNLP) 4. At the PLL, con- tinue walking away from the drill with the trigger held in; the signal strength will decrease.
Locating ® Finding the Transmitter and Its Depth 7. While standing on the FNLP facing the drill, it is possible to “sight in” or align the FNLP with the RNLP. This axis line is at a 90° angle (perpendicula r) to the PLL. Whe re this axis line crosses th e PLL is where the transmitter will be found, below ground surface.
® Locating Locating the Transmitter from the Front The transmitter’s three locations can b e determined in a similar manner as describ ed above starting in front of the transmitter while facing the drill. Start at a location well ahead of the transmitter an d hold in the trigger while facing th e drill.
Locating ® Locating on the Fly Once you are comfortabl e finding the tra nsmitter’s three locating points (FNLP, RNLP, and PLL) it is time to increase your speed at locati ng.
® Locating 4. Step further to the side of the transmitter and agai n find the point where the “–” sign chang es to a “+” (Point 2). 5. Repeat this procedure to find the third location (Point 3).
Locating ® 7. Repeat steps 2 through 6 until the “+/–” signs flip from one to the other over a very small area. Thi s is either the FNLP or the RNLP. To find the other locate point, walk in the assumed direction of drilling. If the signal strength increases you are at the RNLP; if it decrea ses you are at the FNLP.
® Locating Running off Pitch or Calculating Depth from Pitch The transmitter’s depth can be estimated by using the pitch info rmation. Use the following procedure to estimate the depth based on the pitc h, starting with the first ro d.
Locating ® Elliptical Shape of Transmitter Signal Field Transmitter’s Signal Shape It is important to understand some fun damental con- cepts about the transmitter’s electromagnetic sign al and the way the receive r’s antennas read or receive this signal.
