UT622 SERIES

The UT622 Series Handheld LCR meters feature powerful functions, 

high accuracy, fast speed, and long standby time. 

With a clear and intuitive 2.8-inch TFT LCD display, large-capacity rechargeable batiery,

and up to 100kHz test frequency, the meters can be used for longstanding accurate

and convenient measurement in any occasion. 

They are suitable for the measurement and screening of inductance, capacitance,

 and resistance in laboratories, production lines, maintenance points etc.

Recording mode

Recording mode

The recording mode can be used for data statistics

to dynamically obtain the Average, Maximum, Minimum and Number of records

Tolerance mode

Tolerance mode

The tolerance mode can be used for component sorting.

The nominal value, tolerance limit, alarm, LED indicator and counter can be set,

and the percentage deviation between the measured value of the main parameter

and the nominal value can be calculated for qualified and unqualified Compare,

display GO/NG discrimination results.

Tolerance range: 1%~20%

Test speed: 20 times/s(Fast),5 times(Med),2 times/s (Slow) 


3-terminal and 5-terminal test ports

3-terminal and 5-terminal test ports

Support three-terminal test, five-terminal end-face test and Kelvin test line expansion. 

Allow both convenient testing and high-precision testing requirements.

Power supply

Impedance in LCR?

In a circuit with resistance, inductance, and capacitance, 

the hindrance to the current in the circuit is called impedance and is represented by Z. 


What is the electornic meaning of quality factory Q and loss factory D?

The quality factor Q of an inductor is a parameter that indicates how close the device is to pure reactance. The higher the quality factor, the higher the absolute value of the reactance

For capacitor, the item indicating purity is usually expressed by the dissipation factor D, D=1/Q. Therefore the smaller the D, the higher the capacitive reactance and the better the efficiency.


No screen display(blank screen)

If the generator still remains blank screen when power on.

1) Check whether the power supply is connected properly.

2) Check whether the power switch on the rear panel is set to "I".

3) Check whether the power switch on the front panel is connected .

4) Restart the instrument.

5) If the instrument still can't work normally, please contact your UNI-T dealer or local offices for support.



No waveform output

Correct settings but no waveform output

1) Check whether the BNC cable is properly connected to the channel output.

2) Check whether the key CH1 or CH2 is turned on.

3) Save the current settings of the instrument to a USB flash drive and "restore factory settings",  then restart the instrument.

4) If the instrument still can't work normally, please contact your UNI-T dealer or local offices for support.


Can not recognize U disk

1) Check whether the USB flash drive device is working properly.

2) Make sure you are using Flash type USB flash drive device, this instrument does not support hard disk type USB flash drive device.

3) Restart the instrument and insert the USB flash drive again to see if it works properly.

4) If the USB flash drive still can not be recognized, please contact UNI-T dealer or local office and let us serve you.


Maintenace and Cleaning

(1) General Maintenance 

Do not store or put the instrument under direct sunlight for a long time, especially the LCD display panel. Caution:  Sprays, liquids or solvents are not allowed for the instrument or probe  to avoid damage to the instrument or the probe. 

(2) Cleaning 

Check the instrument and probe frequently according to the operating conditions. Fellow the steps to clean the surfaces of the instrument.


Please use a soft cloth to wipe dust on the surface of the instrument and probe. When cleaning the LCD panel, be careful not to scratch the transparent protective film. 


Power off the instrument first and wipe the instrument with a soft cloth.Use a mild detergent or water to clean if necessary.


Do not use any abrasive chemical cleaners as they may damage the instrument or the probe. 


Warning: Make sure the instrument is completely dry before rebooting. Moisture may cause electrical short-circuit or even personal injury!
