Usage Notes For LCR-T4 Multifunction Resistor Capacitor Diode Tester:

6. Test:

When placing the part on the tester, be careful not to use connectors with the same numbers. For example, put the bases of the transistor in connectors 1, 2 and 3.

The tester automatically detects the arrangement of the bases and displays it along with the measured parameters on the LCD.

The order of bases in the first row, from left to right, is as follows.

1 2 3 1 2 2

And the bottom row is as follows

K - A 1 2 3

7.Calibration:

1>.The tester calibration is used to eliminate the errors of its own components and make the final test results more accurate.Calibration is divided into quick calibration and full-function calibration.

2>.Operation method of quick calibration:

1.1>.Short-circuit the three test points TP1,TP2,and TP3 with wires,and then press the test button while paying attention to the screen.The screen color will change to white text on a black background.After the prompt message "Selftest mode ..?" Appears,press the test button once to enter the quick calibration process.

1.2>.If after the prompt message "Selftest mode ..?" Appears,there is no key press within 2 seconds,a normal test process is performed,and finally the resistance value of the short test leads TP1,TP2,and TP3 is displayed.

1.3>.After entering the quick calibration process,some data will appear on the screen,regardless of him.Wait until the flashing character string "isolate Probes!" Appears on the screen,then remove the wires shorting TP1,TP2,TP3.Until the string "Test End" appears on the screen,the quick calibration is completed.

3>.Function calibration method:

1.1>.For the first calibration,the full-function calibration method is used.Full-function calibration needs to be entered from the function menu,and a 220nf capacitor is required.Full-featured calibration performs a more comprehensive calibration process and will take longer.

1.2>.After entering the function menu,rotate the test button to the menu item "Selftest",and then press the test button to enter the full-function calibration process.The flashing string "short Probes!" Will appear on the screen first.At this time,it is the same as the quick calibration.Short-circuit the three test points with a wire and wait for the calibration process to take place.When the flashing string "isolate Probes!" Appears on the screen,remove the wire shorted at the three test points and continue to wait for the calibration process to proceed.When the character string "1-||-3> 100nf" is output,install the prepared 220nf capacitor on the test points TP1 and TP3.

1.3>.Wait until the screen prompts "Test End" and the full-function calibration process is complete.
