LCR-900 have 2 power switch. Line Power Switch 25 on the rear panel for the transformer and then the Power Switch 3 Key on the front panel for the operation system. Switch “ON” the Line Power Switch 25 on the rear panel then press the Power Switch 3 key on the front panel to light the LCD. 1. Open Circuit / Short Circuit calibration: LCR-900 provide Open Circuit/Short Circuit calibration function so that you can measure High resistance and low resistance more accuracy. (1) Open Circuit Set the measuring terminal at “OPEN” condition, press CAL 6 key 2 sec, the main LCD will display <Open>, than press CAL 6 again to start the open circuit calibration, to calibration will need about 30sec, after you have hear “Bi-“ and the LCD will display <PASS>, the LCR-900 have finished the Open Circuit calibration automatically. (2) Short Circuit After Open circuit calibration,press CAL6 key 2 sec again,the main LCD will display<Srt>,and press CAL 6 key again to start the Short circuit calibration, the same as Open Circuit Calibration, it need 30sec. and after “Bi-“, the LCD will display <PASS>. 2. Relative Value Mode: Press REL 13 key to enter the “ Relative Value Mode” after you had key in the standard value from the Digits 15 key. Press Enter 17 key. If the unit must be changed press Range 14 key to change the unit. Then Insert the unit to be measured. The Second LCD will display the different between the standard value and the measuring value in “%”. 13 The equation are as the following: Difference value (%) = | measuring value – standard value | / standard value x 100% NOTE: If the difference value are high than 9999%. The LCD will display<—->only. 3. Sorting Function Mode: Press SORT 11 key to enter the sorting function Mode. Key in the max. difference value (%) and press Enter 17 key. Then key in the standard value and the units. Press Enter 17 key. After your have connect the Measuring object. Press Test 12 key. The Second LCD will display <PASS> or <FAIL>. 4. Display Hold Mode: Press HOLD 10 key. LCR-900 will enter the Display Hold mode. On the upper side of the main LCD will display <HOLD>, The display value on the LCD will be kept un changed. 5. Auto Range Mode: Press FUNC 4 key to enter the auto range mode, the upper side of the main LCD will display<AUTO LCR., LCR-900 will detect the object been measured and set the range to match it automatically. Included what kind and the value etc. 6. Measuring Frequency: Press FREQ 5 key to select the measuring frequency, the range can be 1kHz, 10kHz,100kHz, 100Hz,120Hz 5 ranges. 7. DC Resistance Measurement: Press FUNC 4 key to change the LCR-900 range till the upper side of the main LCD display <DCR>, the LCR-900 was under “DC Resistance Measuring Mode ”. 14 8. Equivalent Impedance of Serial or Parallel circuit: Press FUNC 4 key to change the range till the upper side of the main LCD display<AUTO>, the LCP-900 will select “ Serial Equivalent Resistance” or “Parallel Equivalent Resistance” mode automatically. Or press SER/PAL 9 key LCR-900 will swift to manual control the output mode as “Serial Equivalent Resistance” or “Parallel Equivalent Resistance” mode. The Display of the various Equivalent Impedance is as the following: Equivalent Impedance Mode Main LCD Display Inductor parallel mode Lp Capacitor parallel mode Cp Resistor parallel mode Rp Inductor Serial mode Ls Capacitor Serial mode Cs Resistor Serial mode Rs DC Equivalent impedance DCR 9. Resistance Measurement Upon the Difference, equivalent system “Resistance Measurement” can be separated as Serial Mode (Rs, Serial Mode) and Parallel Mode (Rp,Parallel Mode), user can press FUNC 4 key to set the range to “ R “ position. The LCR-900 will select Rp or Rs automatically. Or press SER/PAL 9 key. The Lcr-900 will swift to manual operation to measure under Rp or Rs. 10. Capacitance Measurement The same as Resistance Measurement. Upon the equivalent System. “Capacitance measurement” can be separated as Serial Mode (Cs, Serial Mode) and Parallel Mode(Cp, Parallel Mode), press FUNC 4 Key to “ C “ position, the LCR-900 will select Cp or CS automatically Or press SER/PAL 9 key to select Cp or Cs mode and then press D/Q/Θ/ESR 7 key to select D/Q/Θ/ESR factor NOTE: D/Q/Θ/ESR can not be selected under “AUTO “mode. The factor will be fixed at the time it been under “AUTO” mode. 11. Inductance Measurement The same as Capacitance Measurement. “Inductance measurement” can be separated as (Ls ,Serial Mode) and (Lp,Parallel Mode), press FUNC 4 key to “L” Position,The LCR-900 will be set under “AUTO” mode. As the Capacitance, press SER/PAL 9 key to manual mode and press D/Q/Θ/ESR 7 key to select D/Q/Θ/ESR factor. NOTE: D/Q/θ/ESR can not be selected under “AUTO” mode. As capacitance measurement. 12. Connect To Computer Refer to the appendix. Key in the RS-232(USB) code to your computer and Connect the LCR-900 to your computer by RS-232(USB) cable. Press PC 8 key, the second LCD will display<RS232>, the LCR-900 been connect to your computer. The output of the measuring result will transfer to the computer.
