Extech LCR200 Passive Component LCR Meter

Extech LCR200 Features

• The Extech LCR200 measures inductance, capacitance, and resistance
• Tests secondary parameters of Q (Quality), D (Dissipation), R (Resistance), θ (Phase), and ESR (Equivalent Series Resistance)
• Higher accuracy than DMMs
• Built-in test fixture
• 5 preset test frequencies
• Dual display with bargraph

Key Functionality

With the Extech LCR200 you can see simultaneous 20,000/2,000 count displays of the primary parameter on the high contrast backlit display coupled with a segmented bargraph display. You can set Hi/Lo limits using absolute values or percentage limits and test with 5 preset frequencies. Open and Short Zero removes unwanted stray impedances from the measurement. Use the built-in test fixture or external test leads (included). You can expand the functionality of your LCR200 with several optional accessories (not included): SMD Component Tweezers (LCR203) and a plug-in SMD Chip Component Fixture (LCR205). A soft pouch storage case (CA900) is also available. The LCR200 has an Auto Power Off function that can also be disabled and a low battery indicator to alert you when to replace the batteries.

Open/Short Calibration

In order to improve the accuracy for high/low impedance measurements , it is recommended to do OPEN/SHORT calibration mode before the measurement. This removes stray impedances in test leads or fixtures.

1. Press the CAL button for greater than 2 seconds to start the open/short calibration procedure:
2. The “CAL” icon and “OPEN” appear in the display
3. With no component connected, press the CAL button. The display will count down from 30 and either “PASS” or “FAIL” will appear in the display.
4. Press the CAL button and “Srt” will appear.
5. Short the input and press the CAL button. The display will count down from 30 and either “PASS” or “FAIL” will appear in the display.
6. Press the CAL button to exit the cal mode.
7. If PASS appeared for both the OPEN and SHORT modes, the calibration data will be saved to external EEPROM.
8. If FAIL appeared for either calibration, the impedance was too large to zero out and the data is not stored.
