  • Page 2: Product Overview

    When using electrical appliances, basic safety precautions should always be followed to reduce the risk of fire, electric shock and injury to persons or property. Read all instructions before using the appliance and retain for future reference. • Check the product before use for any damage. Should you notice any damage on the test leads or casing, do not use.

    CONTROLS AND CONNECTIONS LCD Display Frequency key/sort button Calibration button Power button USB function button Auxiliary function parameter button Relative measurement button Input connection Shield ground terminals 10. Series/parallel button 11. Function button for inductance, capacitance or resistance 12. Hold/Enter button 13.

  • Page 4: Calibration Function

    Measurement Frequency • The meter can provide 5 frequency testing points, namely, 100Hz/120Hz/1kHz/ 10kHz/100kHz. On powering on the default frequency is 1K. • Press FREQ button to select different frequency points for measurement. Note: DC impedance is measured under AUTO OCR mode and measurement frequency is automatically set.
  • Page 5 • Press CAL again and SRI is displayed in the auxiliary display. • Insert a short circuit splice into the testing terminals and then press CAL again to begin calibration. • A countdown from 30 to 0 starts then PR55 is displayed when short circuit calibration is complete.

  • Page 6: Operation

    OPERATION Serial or Parallel Mode • It is suggested to use serial mode for low impedance elements less than 100Ω and parallel mode for high impedance elements more than 10kΩ. • The mode used can improve accuracy of measurement in certain circumstances but in most cases has little influence on the measurement results.
  • Page 7 Resistance Measurement • Press the POWER button to turn on the meter. • Press FUNC so Rp is displayed on the LCD. • Insert the resistance element into the test port or measure using the test leads and clamp. • Press FREQ to select suitable testing frequency.

  • Page 10 (such as this) can be used to measure AC or DC impedance. • The 72-10465 is an intelligent double-display portable LCR digital electric bridge, with DC & AC impedance measurement functions. Impedance is one of the most fundamental parameters to analyze electronic elements and circuits. The resistance of linear diode is defined by Ohm’s Law as part of a DC power scenario.

    Rs = IZsl cos θ Xs = IZsI sin θ Xs/Rs = tan θ θ = tan (Xs/Rs) Reaction is inductive if θ exceeds 0 or reaction is capacitive if θ is less than 0. MAINTENANCE Battery Replacement Warning: Only replace the battery after the test leads are removed and the power is turned off.
  • Page 12 INFORMATION ON WASTE DISPOSAL FOR CONSUMERS OF ELECTRICAL & ELECTRONIC EQUIPMENT. These symbols indicate that separate collection of Waste Electrical and Electronic Equipment (WEEE) or waste batteries is required. Do not dispose of these items with general household waste. Separate for the treatment, recovery and recycling of the materials used. Waste batteries can be returned to any waste battery recycling point which are provided by most battery retailers.
