Measuring range position: 

1. Crange ........Capacitance (0.01pF-10uF) 
2. L range ........Inductance (0.001uH-100mH) 
3. HL range ......Big inductance (0.001mH-100H) 
4. HC range ......Big capacitance range (1uF-100mF) 

All files position are automatic measuring ranges, it is easy to operate. 

NOTE: 

 1. Please reset to “0” before testing a capacitance or an inductance, or errors may be appeared. Even if “0” displayed before measuring, resetting to “0” is needed. 

 2. At the time of resetting to “0”, when“CALCULATING...OK” appeared, please keep pressing for 2 to 3 seconds, and the parameter written to “<DATA SAVED>” will be prompted, then release 

3. Resetting to “0” is forbidden as components are being measured. If you do it, please shut down immediately and restart, then reset to “0”. 

 4. The time of measuring a big capacitance (above 10mF) may be more than one second, and it needs seven to eight seconds to get the measured value of the capacitance (100mF). 
 5. Forbid to measure a capacitance which is not discharged, otherwise it may damage the mainframe.

In the electronic development engineers often need to measure inductance and capacitance, inductance capacitance meter higher prices on the market, and the measurement of small inductors and capacitors small error, the instrument based on the principle of LC resonance, calculated by adding the high-speed microcontroller accurate measurement, 1uH can measure small capacitance and inductance of less than 1pF, the biggest characteristic is the instrument, especially for the production of microwave switching power transformers, inductance measurements.

Four measurement modes (LC modules):

1 ...... C mode. Capacitance (0.01pf-10uf).

2 ...... L mode. Inductance (0.001uh-100mh).

3.hl mode ...... large inductance (0.001mh-100h)

4.hc mode ...... large capacitance (1uf-100mf)

All booths are automatic range, easy to use. In this manner, LC100-A in terms of the measurement range and accuracy can replace any of the inductance and capacitance measuring instrument on the market, the performance parameters of the digital bridge, is a cost-effective instrument.

Technical parameters:

Structure introduction:

Overall renderings. In use, you can use the micro-USB cable to connect to your computer's USB tester power supply, if the user has a USB plug or a DC 5V power adapter directly to the instrument can also be powered mobile phone chargers. Special Note: If you are using the DC plug adapter, certainly very hole, the outer periphery of the negative, and mini USB interfaces polarity error conditions do not occur.

Structure:

Button, a total of five, "reset" 0 "HC" button, a large capacitance, inductance, select "HL" option, "credit" and black extensions button. HC, HL, and of L / C option is self-locking, the press release is 1,0, X represents any function, as follows:

Use:

1. PC USB connection for power and switch tester.

2. Select the mode of the test element according to selected measuring inductance LX, capacitance CX, inductive or capacitive, HC HL, measurement terminal open state, seen on the screen:

Inductance measurement 0.000uh LX:

Capacitive display: Measuring CX 0.00pf

The results showed that: large inductance measurement HL 0.000mh

Large capacitance measurements show: HL 0.00uf

3. Because of the different measuring principle HC file, first elaborated as follows LX, CX, and HL three operating modes:

In the third mode, the measurement zero adjustment requirements. Depending on the method of inductance and capacitance.

In the end turned CX mode, press the "reset" button, the screen displays "Settings ... Well," after the introduction, the screen displays "Timeline" 0.00pf; the case of HL and LX models, terminals shorted, press the "reset" button, the screen displays "Settings ... well," launched, the screen should display "0.000mh" and "0.000uh", the display of the open-end "Out of Range!." Then, you can connect the inductance tester.

In the measurement results is displayed, press the function keys are black, will display the test frequency current.

4. In HC's files, make sure the capacitor is fully discharged measurement, then the negative test fixture capacitors red and black test clip capacitor anode, display test results can be read, to note that the bulk of the measure (more than 10mf), test time It may be more than one second, longer 100mf capacitance test results for about 7-8 seconds before.

NOTES:

1. HC mode measurements electrolytic capacitor, please note that the polarity is negative, red and black.

2. 0 if the measurement is displayed, sometimes need zero, this may be a negative bias, but does not show a significant negative.

3. Is prohibited when the test endmembers zero button is pressed, this action will lead to erroneous results.

4. Non untested capacitor discharge, or may cause damage to the table.

5. Using a 5V power adapter module, ensure the polarity is negative, "otherwise it will damage the module.
