    Separate capacitive function test, the test mode for the continuous measurement of 2uF-50mF capacitors can be measured directly in their circuit (circuit where the measured capacitance required power, after the measured capacitance required to be fully discharged)
    Thyristors and thyristor can only recognize its pinout, and also need to test the thyristor or SCR trigger current is less than the current test instrument can provide, the tester can only provide a maximum trigger current 6mA

    unction menu descriptions:

    1. Switch off

    Enter this Function Tester will immediately shutdown.

    2. Transistor

    Transistor test, it’s also the default Function at power on.

    3. Frequency

    Measurement of frequency, For frequencies below 25kHz the normal measurement is followed by a measurement of

    period time. This additional measurement is only followed after a normal frequency measurement.


    Signal generation, this Function can output square wave .with various of frequency to choice.

    5. 10-bit PWM

    The function ”10-bit PWM” (Pulse Width Modulation) generates a fixed frequency(7812.5Hz) with selectable pulse

    width at the pin TP2. With a short key press (< 0.5 s) the pulse width is increased by 1%, with a longer key press the pulse

    width is increased by 10%. If 99% is overstepped, 100% is subtracted from the result. The function can be exit with a very long key press (> 1.3 s).

    6. C+ESR@TP1:3

    The additional function ”C+ESR@TP1:3” selects a stand-alone capacity measurement with ESR (Equivalent Series

    Resistance) measurement at the test pins TP1 and TP3. Capacities from 2µF up to 50mF can be measured. Because the

    measurement voltage is only about 300mV , in most cases the capacitor can be measured ”in circuit” without previous

    disassembling. The series of measurements can be finished with a long press of RPEWS.

    7. Rotary encoder

    With the function ”rotary encoder” a rotary encoder can be checked. The three pins of the rotary encoder must be

    connected in any order to the three probes of the transistor tester before the start of the function. After starting the

    function the rotary knob must be turned not too fast. If the test is finished successfully, the connection of the encoder

    switches is shown symbolic in display row 2. The tester finds out the common contact of the two switches and shows, if the

    indexed position has both contacts in open state (’o’) or in closed state (’C’). A rotary encoder with open switches at the

    indexed positions is shows in row 2 for two seconds as ”1-/-2-/-3 o”. This type of encoder has the same count of indexed

    positions as count of pulses for every turn. Of course the pin number of the right common contact is shown in the middle

    instead of ’2’. If also the closed switches state is detected at the indexed positions, the row 2 of the display is also shown

    as ”1—2—3 C” for two seconds. I don’t know any rotary encoder, which have the switches always closed at any indexed

    position. The interim state of the switches between the indexed positions is also shown in row 2 for a short time (< 0.5s)

    without the characters ’o’ or ’C’.


    With the menu function ”Selftest” a full self test with calibration is done. With that call all the test functions T1 to T7 (if

    not inhibited with the NO TEST T1 T7 option) and also the calibration with external capacitor is done every time.

    9. Voltage

    Voltage measurement, Because a 10:1(180K:20K) voltage divides is connected toPC3 , the maximum external voltage can be 50V, The measurement can also be exit with a extra long key press (> 4 seconds).

    10. Show data

    The function ,Show Data” shows besides the version number of the software the data of the calibration. These are the

    zero resistance (R0) of the pin combination 1:3, 2:3 and 1:2 .In addition the resistance of the port outputs to the 5V side

    (RiHi) and to the 0V side (RiLo) are shown. The zero capacity values (C0) are also shown with all pin combinations (1:3,

    2:3,1:2 and 3:1, 3:2 2:1). At last the correction values for the comparator (REF C) and for the reference voltage (REF R)

    are also shown. Every page is shown for 15 seconds, but you canselect the next page by a key press or a right turn of the

    rotary encoder. With a left turn of the rotary encoder you can repeat the output of the last page or return to the

    previous page.

    11. FrontColor

    This function can change the color of the font, the 16bit color is encode in RGB(565) format, that mean red maximum =

    31, green maximum = 63,blue maximum = 31, respectively. In the function, a short time press can index the base color to

    change, turn left decrease it value and turn right increase it value. A long time press will save the Result and exit the function, please keep in mind the FrontColor and the backcolor cannot be the same. This will case the LCD show nothing.

    If this happens, you need to do a Selftest , how to enter the Selftest is descriptions at Page 2. Selftest will change the back

    Color to black and font color to white automatically. When the Selftest is finish . you will have the chance to modify the

    color .

    12. BackColor

    This is function is the same as the FrontColor except it’s change the background color .

    13. 1-||-3

    This function can series Measurement the capacitance at TP1 ,TP3, this function can Measurement very small capacitor. A long time press will exit the function.

    14. 1- - 3

    This function can series Measurement the Resistance and inductance at TP1 ,TP3, A long time press will exit the function.
