  • Page 24: When Using External Power

    Single charge cycle is about 160 minutes and charge current is approximate 120mA. If a battery is fully charged, then the 880 will stop charging the battery. WARNING: DO NOT connect to external power when a non-rechargeable battery is installed.

  • Page 25: Operation Instructions

    OPERATION INSTRUCTIONS WARNING: If the component to be measured is a capacitor, be sure that the capacitor is fully discharged BEFORE inserting it into the input sockets or terminals. For large capacitors, it may take longer periods of time for a full discharge. Inserting a charged or partially charged capacitor into the meter’s input sockets or terminals may produce an electric hazard and may also damage the instrument, making it unusable.

  • Page 26: Calibration (Cal)

    Recording State This is the default mode when static recording is enabled. In this mode, LCD will display “MAX AVG MIN” indicator. In a relatively stable range of test data, a beep tone will sound once a recording has been stored. NOTE: When the data fluctuation range is higher than 1%, data record will dynamically be refreshed.

  • Page 27: Enter Cal Mode

    There are two functions under CAL Mode:  Open Cal will reduce the effects of contact resistors and test leads.  Short Cal will minimize the influence of distributed capacitors and resistors on testing high impedance elements. Enter CAL Mode For convenience, OPEN CAL and SHORT CAL are designed to share a button.

  • Page 28: Primary Parameter (Pri)

    Figure 8 - Short Calibration Notes: 1. If test frequency is changed, calibration should be done again before making precision measurements. Once calibration is done on a selected test frequency, calibration data will remain until power off. 2. Either open or short calibration is not associated with measurement function, therefore changing the test function does not require re-calibration.

  • Page 29: Secondary Parameter (Sec)

    Secondary Parameter (SEC) The secondary display of the LCR meter is used to display measured values of four parameters, which provide additional information about the component being tested. These parameters are: D (Dissipation factor), Q (Quality factor), θ (Phase angle), and ESR (Equivalent series resistance).

  • Page 30: Disable Auto Lcr Mode

    “AUTO” indicator on LCD will disappear when auto LCR mode is turned off. Test Frequency (FREQ) The 880 LCR meter uses an AC signal to test and measure components at the input sockets or terminals. With this measurement method, a test frequency must be selected. The test frequency can affect the accuracy of the results depending on what frequency is selected, and what type and value of component is being measured or tested.

  • Page 31: Parallel And Series Measurement Mode

    Parallel and Series Measurement Mode The LCR meter offers the option to select between parallel or series measurement modes. Depending on which mode is selected, the method used to measure the component will be different. Additionally, one measurement mode may provide better accuracies over the other measurement mode depending on the type of component and the value of the component to be tested.

    be measured at higher frequencies such as 1 kHz or 10 kHz. However, a 120 Hz test signal is used to measure inductors that are used for applications such as filter chokes in power supplies, in which are typically operated at 60 Hz AC (in U.S.) with 120 Hz filter frequencies. In general, inductors below 2 mH should be measured at 1 kHz frequency while inductors above 200 H should be measured at 120 Hz.

  • Page 58: Capacitance

    Some inductors are intended to operate at a certain DC bias to achieve a certain inductance value. However, the 880 LCR meter cannot produce such biasing scheme and external biasing should not be attempted because external power would be applied to the instrument and cause serious damage to the meter.
