the internal memory of the LCR-800.

The Open circuit calibration determines the stray admittance and compensates high impedance measurements. The short calibration determines the residual impedance and is used when determining low impedance measurements.

Open circuit

Procedure

The Open circuit calibration measures the stray admittance of the test fixture. This is used for high impedance measurements.



1. Insert the test fixture or cable. Ensure the cables are not shorted and are open.

2. Press the MENU key, then OFFSET, followed by CAP OFFSET.

3. Wait for the calibration to finish. If the OPEN

TEST was successful, the screen will display the following message:

4. Short the cables or test fixtures using a short thick copper wire if necessary.

5. Press R/L offset in the offset menu.

6. Wait for the calibration to finish. If the SHORT TEST was successful the following message is displayed.

Warning

If the test failed, ensure your cables or test fixtures are shorted. Ensure R.H is OFF. After inspection try again.

Component Measuring Guidelines

Background

General Inductors

For measuring Impedance, Capacitance, Inductance, and Resistance, series or parallel equivalent circuit models are available. Usually a component manufacturer will specify how a component should be measured and at what frequency. If not, use the guidelines below. Select the equivalent circuit and frequency according to the component value. For more information about equivalent circuit models and theory see page 124.

Inductors have always traditionally been measured in series equivalent circuits. For large inductors a lower test frequency yields more accurate results. For small inductors, higher frequencies are more accurate.

Air-cored coils

Iron-cored and ferrite inductor

LCR-800 User Manual

Air-cored coils can pick up noise very easily, therefore they should be kept well clear of any test equipment that ma

contain power transformers or display scan circuitry. Also, keep the coils away from metal objects which may modify inductor characteristics.

The effective value of iron-cored and ferrite inductors can vary widely with magnetization and test signal level. Measure them at the AC level and frequency in use. Unlike most inductors, a parallel equivalent circuit is most suitable for iron-cored inductors. When core materials are damaged by excessive magnetization (for example: tape heads and microphone transformers), check that the test signal is acceptable before connection.

Metal component case connection

A large area of metal can add noise to the measurement. Here is how to minimize the effect.

If the metal is connected to one of the terminals, this should be connected to the Hforce terminal side.

If the metal is NOT connected to either of the terminals, connect to the GND terminal.

Wire capacitance

When measuring the wire capacitance, the fixture clips that are marked with H (High Sense)

should always be connected to the

(High Force)/HS

point that is influenced the most by noise.

Background

Note

Voltage bias can be set internally or externally. An internal voltage bias of 2 volts is normally applied to a DUT. External voltage bias is able to accept 0 to 30 volts with a maximum current of 200mA. For external bias voltage connections see page 22. When measuring a DUT, please allow 1 second to stabilize a DUT after a bias voltage is applied. In general a bias voltage should only be applied to capacitors. If a bias voltage is applied to devices with low impedance, inaccurate measurements will occur.

When an external voltage is applied, constant voltage mode (C.V.ON) must be enabled, page 39.

Set constant voltage source

Background

Panel operation

If a DUT needs to be tested at a set voltage, the constant voltage function can be used. Using the C.V. function the LCR will maintain a source resistance of 25Ω. Therefore the test voltage is constant for any DUT impedance greater than 25Ω. Using the constant voltage feature will reduce the accuracy of measurements by a factor of 3.

1. Press 1/C.V to turn constant voltage on or off.

Background

When DUTs are disconnected from the test cables/fixtures during continuous testing, Range Hold can be used to avoid range switching. This is particularly useful for repetitively testing a number of DUTs. For more information on Range and range hold, see the specifications, page 136.

The signal overview section describes the functions and the overall characteristics of the signals used in the handler interface.

The Index signal will become low when the Analog measurement time has completed. When the Index signal is low, the test component can be replaced with the next component. The signal goes high when the next trigger is active.

The Bin Go/No-Go signals go active low when a successful comparison

/O_BIN_13

has been made. For example if a component is assigned to Bin_1, /O_BIN_1 signal goes low until time T4. All the remaining signals (/O_BIN_2~/O_BIN_13) remain high.

When the primary measurement is higher than the MAX limit, O_P_HI will go low until time T4.

FAQ

Q1. What is the correct procedure for Open/Short Zeroing when using the LCR-06A test fixture?

A1. The LCR-06A test fixture is very sensitive and thus must be used correctly.

 For Open Zeroing, make sure that the test fixture wires do not

move and that there is nothing in close proximity to the test clips.

 For Short Zeroing ensure the clips are properly shorted. See page

24 for details.

Q2. Why does Short Zeroing fail?

A2. There are two possible reasons that Short Zeroing can fail.

LCR-800 User Manual

For more information, contact your local dealer or GW Instek at

www.gwinstek.com

/ marketing@goodwill.com.tw.

 The test fixture has an open circuit between the wires and

terminal.

 Some functions can impede the short test. Ensure Range Hold and

Internal/External Bias (R.H and INT.B/EXT.B) are disabled. See pages 40, 39 & 34.

Q3. I cannot see the display clearly.

A3. Use the display contrast control on the rear panel to adjust the contrast.

Q4. When using a terminal program I cannot execute a command.

A4. Make sure the correct terminal characters are used. For example use “CTRL J” ”CTRL M” as the <^J^M> message terminator in a terminal session.
