1 TOOLS URREA's line of diagnostic tools use state-of-the-art technology in order to offer devices to measure, verify, and perform diagnosis, with an excellent balance of accuracy, speed, and versatility. URREA's diagnostics line is classified in 5 product categories: Digital Multimeters Automotive Digital Multimeters Clamp-on Digital Multimeters Infrared Thermometers Digital Multimeters perform standard electrical tests in and circuits including frequency, cycle frequency and wave amplitude and take digital readings of voltage, amperage, and resistance of systems, components, and conductors. They are simply better and easier to read, handle and adjust than Analog Multimeters. They are designed to help service A/C, heating and cooling systems, electric equipment, appliances, computer equipment, electric motors, electrical, and electronic devices, and computers in general. Automotive digital multimeters are very efficient tools used to diagnose most problems in today's sophisticated automotive electronic systems. Their solid construction allows them to be used in the rough and high-paced environments of auto shops. Great for diagnosis on all makes, models, and types of vehicles. View readings from RPM activity cycles, and volts, resistance, frequency, pulse duration, dwell and min-max endpoints in an easy to navigate system. Clamp-on Digital Multimeters are designed to allow the user to measure current in / and high power circuits, outputs and derivations in transformers, capacitors, rectifiers, transmission lines, substations conductors, etc., where a conventional device cannot be used. They also measure current, resistance, amperage, voltage, conductivity, power factor, frequency, among other things without interrupting the connections and energy in the circuit. Thanks to their resistant build they are sufficiently strong to endure the exacting requirements in the transmission and generation of electricity. URREA also offers various accessories for its multimeter line: interface cables, test probes, alligator clamps and temperature sensors. URREA's line of infrared thermometers are ideal for MRO applications, electrical maintenance, automotive repairs and maintenance, manufacturing processes, food processing, A/C maintenance and any other application requiring temperature monitoring. Their accuracy remains constant for a long time. They have various features like auto off to conserve energy, a large DS radius and the ability to obtain readings in Celsius or Fahrenheit.

3 INTRODUCTION DIFFERENCE BETWEEN RMS AND TRUE RMS REPRESENTED ON SINUSOIDAL GRAPHS pv=pure RMS Is the ability to measure and detect alternating voltage. RMS= ROOT MEDIUM SQUARE PURE SINE WAVE GRAPH Important diagnostic equipment measurement characteristic. EQUIPMENT ASSORTMENT Digital multimeters are devices used for taking readings of voltage, amps and impedance, among others. UDXX AND UD1XX FUNDAMENTAL 60 Hz This measurement method does not detect distortions generated by voltage differences in a circuit. SINE WAVE GRAPH 1st. Harmonic DISTORTION SINE WAVE GRAPH 2nd. Harmonic 120 Hz DISTORTION 240 Hz AUTOMOTIVE Designed to view readings directly on activity cycles. UD8X CLAMP-ON Used for taking precise measurements of current, starting current, voltage, etc. UD3XX TRUE RMS Is the ability to measure and detect voltages composed of harmonics (distortions in the size of the sine wave). That is, it measures the amount of distortion in the sinusoidal line caused by non-linear (inductive or capacitive) loads connected to a circuit. REAL SINUSOIDAL CURVE GRAPH EQUIPMENT CESSORIES Allow you to store information and protect your device. UDXXXX DIFFERENCE OR NON-LINEAR LOADS INFRARED THERMOMETERS Long-lasting reading accuracy. Laser view may be turned on or off. UDXX 590

7 EQUIPMENT BOROSCOPE AUTOMOTIVE CLAMP-ON CESSORIES INFRARED THERMOMETERS BOROSCOPES The borescope is an accessory that is used in visual inspections which we do not have a physical space through which we see, which forces us to use an instrument that has a small footprint to access through the holes, and in some cases even allow rotation. They have a light source that works with fiber optics, which ensures the correct lighting to inspect the entire area even when there is a rotation or the head of the borescope. They are used mainly by security personnel, electricians, electrical and electronics mechanics, precision mechanics, auto mechanics or aviation.
