Safety Information Please read the safety note before use: 1.Do not input either AC or voltage; 2.When measuring capacity,the capacitor should be fully discharged, so as to avoid or damaging the instrument; 3.When changing switching function,the lead should be removed from the points; 4. Make sure you have selected the right function, to avoid misoperation, pay attention for safety when measuring. Operation 4.1Testing note: 1. Do not apply voltage to the input socket, so as to avoid damaging the instrument 2. Inductors, meter is used for measuring the inductance of inductors and capacitance of capacitor, it can not be used to measure quality factor of wattless part,when measuring the inductance or capacitance which containing a component of resistance,it may get the wrong readings. 3.When measuring the of the componet in the circuit, the power should be cut off, and remove incentives before connecting lead. 4.Making every measurement , you should inserted black lead into"-"terminal and red lead into the "+" terminal. 5. it is prohibited to short the circuit of input terminal when measuring inductance and capacitance, short-circuit for a long time may rapidly consume the power and may cause internal burning. 4.2 Capacitance measurement 1. The capacitor should be fully discharged; 2. Set the range switch to the proper capacitance range. Insert the black lead of the alligator clip into "-" end and red lead to "+" end ,connect the capacitor pin to the relative input terminal; 3. If the display "1", it indications that the measurement is overrange,you should choose the higher range,if the display one or more zero before the displaying value, you should choose a lower range to increase resolution so as to get a higher accuracy. Note: 1.When it is not showing zero, please transfer the zero-knob until it zero. 2.When using the lead,a stray capacitance value is introduced,the measurement value should subtract the value; 3.When measuring small capacitance you should particularly use short wire to prevent the introduction of stray capacitance 4.If the measuring value zero for all range when measuring an open-circuit capacitor, or show a unstable value when at the large capacitance range when it is used to measure the serious leakage or breakdown capacitor, for all these phenomenon , a preliminary judgement can be maked is that the measured capacitance is serious leakage,make measuring by another instrument to comfirm. 4.3 Inductance measurement 1. Set the range switch to the proper inductance range. connect crocodile clip to both terminal of the inductor. 2. If the display "1", it indications that the measurement is surpass the measuring range, you should choose the higher range, if the display one or more zero before the displaying value, you should choose a lower range to increase resolution so as to get a higher accuracy. Note: 1. If the value of inductance is not marked, increased range gradually from 200uH until the overload signal eliminated and display normal value. 2.When 2 mH range is under use, the lead should be short-circuit firstly to get the inductance value of the leads, the measurement value should subtract this value. When measuring small inductors, you should particularly use short wire to prevent the introduction of stray inductance. 3. This instrument can not be used to measure the quality factor of inductors, the measuring inductance is varied when there is different impedance in the same inductor, you may get the wrong value if you are measuring the inductance of the resistance. 4.4 Resistance measurement 1.Set the range switch at the desired resistance range position. Connect crocodile clip across the resistance under measurement. 2. If the display show"1",it indications that the measurement is surpass the measuring range, you should choose the higher range, if the display one or more zero before the displaying value, you should choose a lower range to increase resolution so as to get a higher accuracy. Note: When measuring resistance below 200Ω,you should short the circuit of the crocodile clip and get the resistance value of the clip ,the measurement should subtract this value.l 4.5 diode measurement (1) Connect the black lead of the crocodile clip to “-” terminal and the red to“+”terminal. (2) Set the range switch at the range position, Connect the lead across the diode under testing. NOTE: a、If the input is open circuit, the instrument will display overrange status. b、The displayed value is forward voltage drop value, when the diode is connected it display overrange status. Ⅴ. Maintenance 1.The meter is of highly accurate electronic apparatus,do not change the internal circuit . 2.Don’t use the meter when the back cover doesn’t cover the meter well. 3.Pay attention to the situation of the 9V ,if it is lack of power ,“- +” signal will be showed on the LCD. change the same type of quickly so as not to affect the measurement. Package Included: 1* LCR meter(9V not Included) 1* Pair of crocodile clip 1* Portable bag
