5. Measurement Modes and Parameters

5.1 Auto Measurement

In AUTO mode, the LC1020E automatically identifies the component type (Resistor, Inductor, or Capacitor) and switches to the appropriate measurement mode, simplifying testing.

5.2 Dual Parameter Display

The device simultaneously displays a primary parameter (L, C, R) and a secondary parameter (X, D, Q, θ, ESR), providing a comprehensive analysis of the component under test.

5.3 Test Frequencies and Voltage Úrovně

The LC1020E offers multiple test frequencies and RMS voltage levels for versatile measurements:

• Frekvence: 100Hz, 120Hz, 1kHz, 10kHz, 100kHz
• RMS svtage Úrovně: 0.1 V, 0.3 V, 0.6 V
• Vnitřní zaujatost: 0.0V, 0.5V

6. Smart Sorting & Comparison Mode

The smart sorting feature allows for efficient screening of components based on preset nominal values and tolerance limits. This mode calculates the relative error (%) and provides alerts via sound or LED if components fall outside the specified range.

6.1 Setting Nominal and Tolerance

1. Navigate to the Sorting/Comparison mode in the menu.
2. Set the desired nominal value for the component (e.g., 100nF for a capacitor).
3. Definujte procentuální tolerancitage (0.1 % až 99.9 %).

6.2 Performing Sorting

Once settings are configured, test components. The device will indicate whether the component meets the criteria (Pass/Fail) and track success/fail counts.

7. Kalibrace

For optimal accuracy, perform open/short calibration periodically or when changing test leads. This compensates for stray capacitance and inductance in the test setup.

7.1 Open Calibration

With no component connected to the test leads, initiate the open calibration process from the menu. This measures and compensates for stray capacitance.

7.2 Short Calibration

Short the test leads together (connect positive to negative) and initiate the short calibration. This measures and compensates for residual inductance and resistance in the leads.
