Type: Voltage Regulator

Product name: Transistor Tester Kit

Product model: WK-56-61

Working voltage: DC9V (9V laminated battery)

Shell size: 96*103*23mm

Measurement range: automatic detection of PNP and NPN type bipolar transistors, N, P channel MOSFETJFET field effect tubes, double diodes, thyristors, capacitors.

1. Measurement of non-polar capacitance, note that the measurement of large-capacity capacitors first short-circuit capacitor legs, discharge, otherwise it may damage the instrument, if the charged measurement is very easy to cause the instrument to display the CELL and can not be used normally in this case we are not responsible for Oh, can only change the chip, please be sure to pay attention to.

2. Detect a 1000UF electrolytic capacitor, this capacitor ESR is low, some general quality capacitors are usually low capacitance:

3. Capacitance measurement range from 25pf to 100mF (100,000UF)

4.Measure a 100UF electrolytic capacitor while displaying the ESR value (this value is only displayed when the capacitance is greater than 2UF). Sometimes the capacitance capacity is normal, but this value is too large meaning that the capacitor has failed, and it is very effective to use to check the quality of some electrolytic capacitors stored for a long time.

Product Features:

1.One button measurement operation, delayed automatic power off. Shutdown current is only 20nA, support battery operation.

2.Automatic detection of PNP and NPN type bipolar transistors, N, P channel MOSFETs, JFETs Field Effect Tubes, diodes, double diodes, SCRs, resistors, capacitors, inductors. Automatic detection of pin definition.

3. Measure the current amplification factor (B) of the bipolar transistor and the on-voltage (Uf) of the emitter junction. Darlington transistors can be identified by high threshold voltage and high current amplification factor.

4. The protection diodes inside bipolar transistors and MOSFETs can be detected and displayed on the screen.

5. Measure the threshold voltage and gate capacitance of the MOSFET.

6. Support the measurement of two resistors, potentiometer can also be measured. If the potentiometer is adjusted to its end, the tester cannot distinguish between the middle and both ends of the pins.

7. The resolution of the resistance measurement is 0.1 ohms, and the maximum measurement value is 50M ohms.

8. Capacitance measurement range from 25pf to 100mF (100,000uF). Resolution up to 1pF Inductance measurement range is 0.01MH-20H, below 0.01MH will be shown as resistance.

9. The equivalent series resistance (ESR) of capacitors above 2UF can be detected. The resolution is 0.01 ohms. This function is very important for detecting capacitor performance.
