• 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.

Extech 380400 Resistance Decade Box offers 7 decades of resistance ranges from 1 to over 11MΩ (in 1Ω steps). Slide switches allow easy addition and subtraction of resistance values. Binding posts (3) offer simple and secure connections.

This device can be used to verify the calibration integrity of MultiMeters, LCR meters, Calibrators, etc. Connect as described above in the Binding Post Connection section. Set the resistance switches to output the desired resistance. Ensure that the voltage supplied by the device under test does not overload the 0.3W internal resistor power rating. The device under test should read the value of resistance selected on the tester. If it does not, the device under test may need calibration, adjustment, or repair.

The 28 front panel switches are used to select the resistance that will be available on the RED and BLACK terminals. When a switch is set to the IN position, the value printed above the switch is added to the total resistance available at the posts. When the switch is set to OUT it is excluded from the total resistance. If all of the switches are set to OUT, the total output resistance is zero (+ 0.3Ω internal resistance – approx.). For example, if the desired output value is 10.5KΩ, set the following switches to the IN position: 10K, 400Ω, and 100Ω.

In heavy duty durable construction housing used for product design or calibration checks.
