Remark D < 0.1
If D > 0.1, the accuracy should be multiplied by 1+ D^2
Zc = 1/2πfC if D<<0.1 in capacitance mode
Zl = 2πfL if D<<0.1 in inductance mode
Sub-display parameter accuracy
Ae = impedance accuracy
Definition: Q = 1/D
Rp = ESR(or Rs) x (1+1/D^2)
(1) D value accuracy De = ±Ae x (1+D)
(2) ESR accuracy Re = ±Zm x Ae(Ω)
ie, Zm = impedance calculate by 1/2πfC or 2πfL
(3) Phase angle θ accuracy θe = ±(180/π) x Ae(deg)
Operating Instruction:
NOTE:.
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 CAL○6 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.

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.
