4.3 Test Ports

The LC1020E adopts a solution that integrates both three-terminal

and five-terminal test ports, meeting the requirements for both

convenient testing and high-precision measurements. The test

ports are shown below:

Complete five-terminal test slot

Convenient three-terminal test hole

High terminal Low terminal Protection terminal 26

The three-terminal test port of this instrument uses standard rubber sockets, making it convenient to use inexpensive rubber plugs, such as alligator clips, for test leads. This is easy for expanding testing applications, but its downside is lower testing accuracy. To improve the accuracy when using external test leads, the LC1020E series is also equipped with a five-terminal test slot. With professional test fixtures, it allows for complete four-terminal measurement using external leads, thereby ensuring higher testing accuracy.

5.OPERATION GUIDE

5.1 Power On and Off

Long press the power button

to turn on the device, and it will

enter the measurement interface (default). To power off, long press

the power button

for more than 2 seconds while the device is

on.

5.2 Parameter Selection

5.2.1 Frequency Selection

The LC1020E series handheld LCR meter applies an AC test signal to

the component under test (DUT) for measurement. Frequency is one

of the main parameters of the AC signal source. Due to the non-ideal

nature of components and the presence of parasitic elements, as

well as the effects of test ports and test lead parasitics, the same

component may show different measurement results when tested

at different frequencies. Therefore, before measurement, it is

important to choose an appropriate frequency.

There are two methods to change the test frequency:

Method 1: Press

button to cycle through the preset frequen-

cy points in order. The cursor will automatically move to the

frequency setting, and the selected frequency will be highlighted

(background highlighted), as shown in the figure.

Method 2: Use

buttons or press

button to move

the cursor to the frequency setting, select the frequency, and then

6.7 Calibration Settings

Press

buttons to move the cursor to the “Calibration Settings”

option, then press

button to enter the calibration settings.

Press

buttons to select “Open” or “Short” calibration. Press

to start the calibration.

The calibration function includes two types: open-circuit calibration

and short-circuit calibration. Calibration effectively reduces the

parasitic errors caused by the test leads. Short-circuit calibration

helps reduce the effects of contact resistance and lead resistance on

low-impedance measurements (suitable for low-impedance com-

ponent measurements). Open-circuit calibration helps reduce the

effects of parasitic capacitance and resistance between the test

leads on high-impedance measurements (suitable for high-imped-

ance component measurements).

Performing both calibrations together effectively reduces the

impact of these factors, ensuring accurate and precise measure-

ments.

Calibration Method:

Before entering the calibration function, please ensure that the two

test ends are either open (test fixtures are disconnected) or shorted

(test fixtures are connected to a shorting piece). Press

button

to start the calibration, and the calibration status will be displayed.

Once the calibration is complete, the word “Complete” will appear,

as shown in the figure. After calibration is finished, long press

button to exit.

Note: Do not change the status of the two test ends during the calibration process.

7.QUICK APPLICATION GUIDE
Warning: Do not measure charged capacitors or inductors; they must be discharged before measurement, or it may cause damage to the instrument. If measuring onboard components online, ensure the component is powered off and not directly measuring the power circuit. When used in dusty environments, the instrument may become dirty. It should be cleaned regularly to protect the test ports and reduce dust entry. Accumulated dust, due to its conductivity, can affect the instrument’s performance over time.
36

Do not place the instrument directly in explosive, direct sunlight, or overheated environments.
TipTo achieve accurate measurements, perform open and short-circuit calibration as described in the “Calibration Function” section before measuring. Test fixtures can use rubber plug crocodile clips or Kelvin test clips.
7.1 Operation Recommendations
Range Selection: Usually, the auto range is sufficient. For comparing characteristics at different ranges or if specific impedance components are not measured accurately, you can manually adjust the range. When the impedance of the device is uncertain, start with the 100 range and then increase the range. Higher ranges give more accurate results. If the results suddenly change, the range is too high, so switch to the previous range.
Frequency Recommendations: Resistance: Use 1kHz, 0.6V for most cases. For large wound resistors, use 100Hz to reduce inductive effects. Capacitance: Use 1kHz, 0.6V, and for electrolytic capacitors, use 120Hz. A general rule is to use high frequencies for small capacitors and low frequencies for large capacitors. Inductance: Use 1kHz, 0.6V. The general rule is to use high frequencies for small inductors and low frequencies for large inductors.
Bias Voltage: Typically used for measuring electrolytic capacitors. At this time, the output level can only be 0.1V or 0.3V.
37

Output Amplitude: Typically, 0.6Vrms is used, while for online measurements, 0.1V is used.
7.2 Charging the Instrument
Connect the instrument to the power source using the included power adapter and Type-C USB cable. After connecting to the power source, the power button indicator on the front panel of the device will light up red, as shown in the image
Power Charging Indicator
7.3 Instrument Power On
When the battery has sufficient charge or when powered using a Type-C USB cable, press and hold the power button to turn the instrument on. The instrument will display the brand animation during startup, as shown in the image
38

7.4 Component Measurement
It is recommended to perform open and short circuit calibration before measurement. After the instrument powers on and enters the test interface, the system’s default parameters (main parameter set to automatic measurement, range set to automatic measurement) will be applied. Insert the device under test into the test slot, or use appropriate testing accessories (such as rubber plug-crocodile clips, Kelvin test clips, etc.) to connect the component under test. The instrument will automatically recognize the component and provide the corresponding measurement result. Read the measurement result from the screen.

7.5 Firmware Upgrade

Enter Bootloader Mode: In the powered-off state, first press and

hold

button, then press

button. When the screen shows

“Bootloader,” it means the device has entered firmware upgrade

mode.

Connect to the Computer: After entering bootloader mode,

connect the device to the computer using a Type-A to Type-C data

cable. The computer will recognize a new drive.

Copy the File: Open the firmware ZIP file downloaded from the

official website, and drag the .bin firmware file into the drive. The

upgrade will begin automatically. The process is quick, and you can

monitor the progress on the instrument’s screen.

Reboot After Upgrade: Once the upgrade is complete, press and

hold

button to restart the device, completing the firmware

upgrade.

9.MAINTENANCE AND CARE
Warnings: Do not attempt to repair the instrument by yourself. Only qualified professionals should maintain and repair the instrument. Be cautious of liquids entering the instrument and ensure that no foreign objects, especially conductive materials, are left inside.
9.1 Troubleshooting
If the instrument fails to turn on, check the battery, external power supply, and power socket. Also, verify if any buttons are unresponsive. If the test results are abnormal, first inspect the test accessories for any issues. Check if the spring contacts inside the testing slot are damaged. Also, carefully review the user manual to ensure that you are using the instrument correctly. Do not replace components or specific parts without proper knowledge. For repairs that cannot be identified, please contact the authorized distributor or our after-sales service.
9.2 Cleaning
Before cleaning, ensure the instrument is turned off, and disconnect both the external power supply and the battery. Prevent water or other liquids from entering the instrument through the testing slots, buttons, or seams. If liquid enters the device, immediately stop using it and remove the power and battery. Use a soft, clean cloth dampened with diluted neutral detergent to gently wipe any dirt or stains. Avoid scratching the surface. After cleaning, allow the instrument to dry completely before using it again.
