LC100-A High precision digital Inductance and Capacitance meter LC100A multimeter/capacitance meter/inductance meter

Engineers engaged in electronic development often need to measure inductors and capacitors, the price of inductors and capacitors on the market is higher, and the measurement of small capacitance inductors and small errors, the instrument is based on LC resonance principle, adding high-speed microcontroller calculation of accurate measurement, can measure small capacitance inductors 1uH less than 1pF, the biggest is the characteristics of the instrument, Especially suitable for microwave production switching power transformer, inductance measurement.

Four measurement modes (LC module) :

one Mode C. 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 and very easy to use. In this way, the LC100-A can completely replace any kind of inductor and capacitor to the market in terms of measurement range and measurement accuracy, and is a digital bridge of performance parameters and a cost-effective instrument.

Technical parameters:

Structure introduction:

The overall effect. When in use, you can use the micro USB cable to connect to the USB tester power supply of the computer, if the user has a USB plug or DC 5V power adapter can also be powered directly to the meter for the mobile phone charger. Special note: If you are using a DC plug adapter, make sure that the pole hole is negative around the periphery, while the micro USB interface does not suffer polarity error conditions.

Instrument structure:

Button, a total of 5, "reset" 0 "HC" button, large capacitor, inductor, select "HL" option, "Letter of credit" and black button for extended function. The choices of HC, HL, and L/C are self-locking, the news release is 1,0, and X represents any function, as shown in the table below:

Use:

one. Connect computer USB as power and switch tester.

2. According to the choice of the mode of the element to be measured, select the measurement inductance LX, capacitance CX, inductance or capacitance, HC HL, in the measurement terminal open state, as seen from the screen:

Inductance measurement 0.000uh LX:

Capacitance display: Measuring CX 0.00pf

The results show that the large inductance measure HL 0.000mh

The measurement of large capacitance shows HL 0.00uf

3. Due to the different measurement principles of HC files, the following three operating modes of LX, CX and HL are first described:

In three modes, the requirement of zero adjustment is measured. Depending on the inductance capacitance method.

In the CX mode of the terminal, press the "Reset" key. The screen displays "Set... Ok "after launch, the screen shows" Timeline "0.00pf; HL and LX mode, in case of short circuit of the terminal, press the "reset" key, the screen displays "Set... Ok "after launch, the screen should display" 0.000mh "and" 0.000uh "after showing the open end" out of range!" . Then, you can put the inductance connection tester to test.

When the measurement results are displayed, the function keys are all black and the current of the test frequency will be displayed.

4. In the HC file, please ensure that the capacitor is fully discharged for measurement, then red test fixture capacitor negative, black test clamp capacitor anode, read the display test results can be, it should be noted that for large capacity measurement (more than 10mf), the test time can exceed 1 second, the longer the test time is 100mf capacitor, about 7-8 seconds before the result.

Note:

one. HC mode for measuring electrolytic capacitors, please note that the polarity is negative, red and black.

2. If the measurement in the display 0, sometimes also need to zero, this may be a negative deviation, but does not show negative.

3. Do not press the return to Zero button when testing the end element. This operation will result in incorrect results.

4. It is strictly forbidden to discharge the capacitor without testing, otherwise it may cause damage to the table.

5. Use 5V adapter module power supply, make sure the polarity is negative ", otherwise it will damage the module.
