GETTING STARTED LCR-800 User Manual Zeroing Zeroing calibration Power Supply + Background + LCD EXTERNAL BIAS 30V 200mA MAX MAX CAT Don’t connect Open and short circuit calibration (zeroing) should be performed on a daily basis to correct for cable and fixture errors before taking measurements. When test fixtures or test cables are changed, the zeroing process should be performed again. All data performed during the calibration is stored in the internal memory of the LCR-800.
GETTING STARTED Warning Short circuit LCR-800 User Manual If the test failed, ensure your cables or test fixtures are open and not shorted. Ensure R.H is OFF. After inspection try again. Component Measuring Guidelines The short test will calibrate the short circuit impedance of the cables or test fixtures. This is used for low impedance measurements Background 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.
GETTING STARTED General Capacitors LCR-800 User Manual Air-cored coils Air-cored coils can pick up noise very easily, therefore they should be kept well clear of any test equipment that may contain power transformers or display scan circuitry. Also, keep the coils away from metal objects which may modify inductor characteristics. Iron-cored and ferrite inductor The effective value of iron-cored and ferrite inductors can vary widely with magnetization and test signal level.
BASIC MEASUREMENT LCR-800 User Manual Measurement Item Description BASIC MEASUREMENT In general, two measurement items, primary and secondary, are combined in a single measurement. The following table shows the available combinations. Details of the measurement modes and the circuit theory and formula can be found in the appendix, page 124. Basic Measurement details how to measure individual components and how to configure the LCR-800 settings.
BASIC MEASUREMENT Parameter Configuration LCR-800 User Manual Displayed measurement unit Measurement Speed Measurement units The LCR-800 series support 3 different measurement speeds: slow, medium or fast at approximately 1, 5 or 12 (LCR-829/827/826) measurements per second. The faster the measurement speed, the lower the accuracy. Conversely the slower the measurement speed, the higher the accuracy. The measurement speed and accuracy are dependent on the mode, voltage and frequency.
BASIC MEASUREMENT Panel operation Measurement Modes Measurement mode Panel operation Note LCR-800 User Manual The LCR-800 has a number of different measurement modes. Primary and secondary measurements are displayed on the screen simultaneously. For detailed information regarding the measurement combinations, see the specifications on page 136. The measurement combinations are shown in the table below.
BASIC MEASUREMENT Panel operation LCR-800 User Manual The LCR-821 can provide 504 different frequencies with a 5 digit resolution including decimal places. Any frequency can be keyed from the number pad, and the closest available frequency (of 504) will be selected automatically. The LCR-818/829 has 503 different frequencies and the LCR-817/827 and LCR-816/826 have 489 and 245, respectively. 1. Press the 7/Bias key on the number pad to cycle from internal to external bias.
BASIC MEASUREMENT LCR-800 User Manual 1V 1.1kHz The nearest frequency will be selected from the 504(LCR-281) nominal frequencies, and updated in the display. Here, the nearest frequency to 1.1kHz is 1.0909kHz. Note After the test frequency has been changed, the zeroing must be performed again. See page 24 The voltage is updated in the display. If the voltage entered is outside the allowable voltage range, the nearest voltage is selected.

FAQ LCR-800 User Manual For more information, contact your local dealer or GW Instek at www.gwinstek.com / marketing@goodwill.com.tw. 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.

INSTEK LCR METER-RS232 CODE Ver 2.2 2010/05/03 Command Reference z Message Terminator (Last data byte with END message) or : New Line or ASCⅡ Line Feed Character (Hex 0A).
z Initialization 1. Power on the LCR Meter 2. Selects “MANU” mode. How to change MANU mode? Please refer to user manual showing about the panel description (13) in chapter 3. 3. PC sends command COMU?^END^M (or ^J^M) 4. Waiting for LCR Meter response. If LCR Meter response is COMU:ON..^END(or ^J^M) then go to step 5. If LCR Meter response is COMU:OFF.^END(or ^J^M) then check below: (1) LCR Meter‘s baud rate set 38400(default),so PC have to set the same. (2) LCR Meter’s RS232 item have to be set on.

z How to get test result? Two ways reach to the goal.. 1. Trigger mode is selected to AUTO mode: If the AUTO mode is selected, LCR Meter will send test result to pc after process the measurement automatically. PC doesn’t need to send any command. 2. Trigger mode is selected to MANU mode: If the MANU mode is selected, LCR Meter doesn’t process the measurement and send test result to pc automatically. PC have to send a command of MAIN:STAR^END^M(or ^J^M) to LCR Meter.
z Test Result Format Ex: When LCR Meter have Processed Measurement, then will sequent send 2 command for test result automatically. Refer to below: Ex: When C=1nF,D= .0045 (C/D mode and display mode is VALUE) 1. Primary factor of test result. (It doesn’t include primary's unit). LCR Meter response MAIN:PRIM 1.0000^END ASCII CODE = 4D 41 49 4E 3A 50 52 49 4D 20 20 31 2E 30 30 30 30 0A (Hex format) Positive symbol 2. Secondary factor and primary’s unit LCR Meter response MAIN:SECO .
Ex: When R=1kohm,Q= .0005 (R/Q mode and display mode is VALUE) 1. Primary factor of test result (It doesn’t include primary's unit) LCR Meter response MAIN:PRIM 1.0000^END ASCII CODE = 4D 41 49 4E 3A 50 52 49 4D 20 20 31 2E 30 30 30 30 0A (Hex format) Positive symbol 2. Secondary factor and unit LCR Meter response MAIN:SECO .0005k ^END ASCII CODE = 4D 41 49 4E 3A 53 45 43 4F 20 20 2E 30 30 30 35 6B 20 0A (Hex format) Positive symbol Primary factor’s unit Ex: When R=-1kohm,Q= -.
C/R mode add a secondary factor’s unit Ex: When C=1nF,R= .0045k ohm (C/R mode and display mode is VALUE) 1. Primary factor of test result (It doesn’t include Primary's unit). LCR Meter response MAIN:PRIM 1.0000^END ASCII CODE = 4D 41 49 4E 3A 50 52 49 4D 20 20 31 2E 30 30 30 30 0A (Hex format) Positive symbol 2. Secondary factor and unit LCR Meter response MAIN:SECO .
EX: If the impedance of “Device-under-test” is small than the existing measurement range of the LCR Meters, LCR Meters will send message as below: LCR Meter response PRIM:OV01 ^END ASCII CODE = 50 52 49 4D 3A 4F 56 30 31 20 0A (Hex format) C/R mode add a secondary factor’s unit Ex: When C=.00001nF,R= OVER kohm (C/R mode and display mode is VALUE) 1. Primary factor of test result (It doesn’t include Primary's unit). LCR Meter response MAIN:PRIM .
z Continuous Command When you would like to send two commands or more, you have to send a code between two commands. Refer to below: or <^J> : New Line or ASCⅡ Line Feed Character (Hex 0A). Last Command need add two codes. Refer to below: or <^J> : New Line or ASCⅡ Line Feed Character (Hex 0A). : ASCⅡ Carry Return Character (Hex 0D) Example: Setting Frequency, Voltage and Test Speed PC send command MAIN:FREQ 1.00000< ^END>(or <^J>) MAIN:VOLT 1.
z Off Line Function: PC disconnect with LCR Meter. PC have to send a command COMU:OFF.^END^M( or ^J^M )to LCR Meter. LCR Meter will respond a command COMU:OFF.^END to PC and recover display after receive PC command. Command String: PC sends command COMU:OFF.< ^END^M> or <^J^M> ASCII CODE = 43 4F 4D 55 3A 4F 46 46 2E 0A 0D (Hex format) LCR Meter response: COMU:OFF.
