CST to the industry. 2. THEORY OF OPERATION The Magna-Trak 100 locator finds ferromagnetic objects by sensing the magnetic field radiated by the object. The locator contains two sensor coil assemblies that are precisely spaced and electronically balanced to achieve a near magnetically-balanced operating condition.
3. FEATURES • Rugged high-impact plastic enclosure with aluminum sensor pole • Powerful magnetic speaker with waterproof Mylar cone • Lightweight, comfortably balanced for easy handling • Easy view LCD display for visual signal strength and battery information: includes two digit numeric signal indicator, expanding analog Bar-Graph signal indicator, and flashing “Low Battery”...
4. BASIC OPERATION AND DESCRIPTION 4.1 Power On/Off Switches Press “ON” once to activate the locator circuitry. Press “OFF” once to turn the battery power off. 4.2 Volume and Sensitivity Control Knobs Rotate the volume knob to the desired audio volume level. Full volume is achieved when the knob is turned fully clockwise.
5. BATTERY REPLACEMENT The LCD will display a flashing “Low Battery” warning when the batteries fall below a predetermined voltage level, alerting you to replace the batteries soon. Several hours of battery life remain; however, in cold temperatures, this time may be shorter. Replace the batteries as follows: Turn the power off.
6. FIELD OPERATION The recommended search position is a 45° angle from the earth’s surface. Scan the locator pole from side-to-side in a slow sweeping motion while walking in a steady direction. Maintain a consistent height above the ground during the side-to-side sweeping motion.
6.1 Water Locations The pole section of the locator can be submerged into water, up to just under the plastic case (Fig. 3). Fig. 3 6.2 Locating Near a Steel Fence Move or slide the locator across the ground while holding the length of the locator body perpendicular to the fence.
7. SIGNAL RESPONSE Figure 5 shows audio and LCD visual signal response to: 1: no object, 2: one small deeper metal target, and 3: a second larger and shallower metal object. The LCD display indicates both the numeric digital and analog bar-graph response as the locator passes over the ground.
7.1 Typical Signal Responses The metal handles on the septic tank cover Signal Response will provide a usable signal to determine the location of the actual cover (Fig. 6). Fig. 6 Large metal objects may cause double Signal Response signals as indicated (Fig.
