Components
| Item | Description | Quantity |
|---|---|---|
| 7 Low Electrode | LOW side test pin | 1 |
| 8 Stage | Area for DUT placement | 1 |
| 9 High Electrode | HIGH side test pin | 1 |
| 10 STD LOAD | Standard resistor (100Ω) | 10 |
| 11 L-Shape Bracket | For stability, reducing BNC improper force (screws fixed by default) | 1 |
Installation
1. Turn the both fixing handles of BNC terminals from the LCR-15A test fixture toward left side until the gap of the BNC external sleeve faces upward.
2. Align the gap with the salient point of the BNC terminal from the LCR test instrument and insert it firmly into place. Turn the both fixing handles of the BNC terminals from the LCR-15A test fixture toward right side until the external sleeve of the BNC is fixed stably into place.
Note: When the L-shape bracket is employed, take off the nut from the ground terminal prior to test fixture installation. Follow the steps above for proper installation followed by fastening the nut so that the test fixture can be held tightly when DUT is inserted.
Note: Refer to the diagrams below for details of L-shape bracket installation.

Additional Error Correction (OPEN/SHORT/LOAD ≥ 3MHz)
The following formulas apply for error correction:
Ze = {A + (Zs/Zx + Yo x Zx) x 100} %
| Parameter | Formula | Unit |
|---|---|---|
| A Proportional error | 0.375 x (f/10)² | % |
| Yo Open repeatability | 0.005 + 10 x (f/100) | µS |
| Zs Short repeatability | 20 + 30 x (f/10) | mΩ |
Where f is the frequency in MHz.

Measurement
WARNING: Before measurement, be sure to read the operating instructions to avoid danger.
1. Set measuring conditions with parameters, and install the LCR-15A test fixture.
2. Execute the CORRECTION mode. Set LCR-15A for the FIXTURE COMPENSATION item to execute parameter compensation (CABLE LENGTH item will be unavailable). If an extension cable is used, disable FIXTURE COMPENSATION (OFF) and select an appropriate CABLE LENGTH option.
3. Open Circuit Test:
Pull the LOW side test pin leftward [adjust]. Loosen the High side locking screw [unlock]. Move the HIGH side test pin rightward [adjust]. Loosen the LOW side test pin [adjust]. Ensure the test pins of both LOW and HIGH sides are contacted in a short circuit. Implement the open circuit test to display "OPEN" ON.
4. Short Circuit Test:
Pull the LOW side test pin leftward [adjust]. Loosen the High side locking screw [unlock]. Move the HIGH side test pin leftward [adjust] to the center of the test stage. Loosen the LOW side test pin [adjust] so the test pins of both LOW and HIGH sides contact each other in a short circuit. Implement the short circuit test to display "SHORT" ON.
5. HF LOAD Calibration (Recommended for frequencies > 3MHz):
Pull the LOW side test pin leftward [adjust]. Loosen the High side locking screw [unlock]. Move the HIGH side test pin rightward [adjust] and place the STD-LOAD to the center of the test stage. Adjust the HIGH side test pin to contact the right side of the STD-LOAD, then fasten the locking screw [lock]. Loosen the LOW side test pin [adjust] so the test pins of both LOW and HIGH sides contact the STD-LOAD properly. Implement the HF LOAD test to display "HF LOAD" ON.
6. DUT Measurement:
Pull the LOW side test pin leftward [adjust]. Loosen the High side locking screw [unlock]. Move the HIGH side test pin rightward [adjust] and place the DUT (Device Under Test) to the center of the test stage. Adjust the HIGH side test pin to contact the right side of the DUT, then fasten the locking screw [lock]. Loosen the LOW side test pin [adjust] so the test pins of both LOW and HIGH sides contact the DUT for measurement. The latest calibration status will be shown in the bottom of the LCD display (item and measuring cable length or test fixture model).
7. After completing the measurements, remove the component from the test fixture.
Note: It is required to place DUT into the test fixture in an exactly vertical way without any tilt, skew, or wobble. Do not fasten the adjusting screws overly in case of thread stripping and over compression on DUT. Also, do not overly loosen the screws in case of accidental drop out of screws.
