Multi-functional transistor tester for automatic detection of NPN and PNP transistors, N channel, P channel, MOSFET and JFET, diodes, dual diode, thyristor, automatic identification of the transistor pinout. It also can be used for frequency measurement and PWM signal generator.
Note : HW-849A on board working remains same.
Note: The capacitor must be discharged before measuring capacitance. Otherwise, there is a high possibility that the meter will be damaged.
Features:
- Test NPN and PNP triode common emitter current amplification factor, base-emitter threshold voltage, and collector-emitter leakage current at turn-off.
- Identification of Darlington transistors through triode base-emitter threshold voltage and high current amplification factor.
- Detect power diodes and FET built-in protection diodes.
- Test FET gate-source turn-on threshold voltage, drain-source on-resistance, and gate-source capacitance.
- It can measure up to 2 resistors at a time, so the adjustable resistors of the three feet can also be measured. If the adjustable resistor is adjusted to the endpoint, only one resistance value can be measured.
- For capacitors larger than 90nF, the equivalent series resistance (ESR) is measured at the same time. The resolution of the equivalent series resistance is up to 0.01Ω.
- Resistance measurement: Max. 50MΩ
- Resistance resolution: 0.01Ω
- Capacitance measurement: 25pF~100mF
- Capacitance resolution: 1pF
- Inductance measurement: 0.01mH~20H
