Measuring the current amplification factor (B) of the bipolar transistor and the turn-on voltage of the emitter junction ( ). transistor amplification factor can be identified by the high voltage and high current. can detect bipolar transistors and MOSFET's internal protection diodes and displayed on the screen. Feature - Color: As Shown. - Material: PCB+LCD. - Size: 7 x 7 x 2cm. - Using 8, 168 or 328 microcontroller. - 2x16 character LCD display results. - One-button operation, automatic power off. - Shutdown current of only 20nA, support for battery operation. - Low-cost version without the crystal, auto power off. 1.05k version of the software 168 or in sleep mode when no measurement to reduce power consumption. -Automatic detection PNP and NPN bipolar transistor, N, P-channel MOSFET, JFET, diodes, dual diode, thyristor . Automatically detects the pin layout. - The voltage and current amplification factor of the emitter junction of the bipolar transistor measurements. - transistor through a high voltage and high-current amplification factor identified. pairs of bipolar transistors, MOSFET protection diode testing. - The voltage value 11 and of a MOSFET is measured. - Supports two resistance measurements and symbols show the highest four numbers and units. Both ends of the resistor symbol is shown connected to the tester probes number (1-3). Therefore, the potential can also be measured. If the potentiometer is adjusted to its end, the tester can not distinguish between the middle and the ends of the pin. - Resistance measurement resolution is 0.1 ohms, the highest measured value 50M ohms, can be detected and measured a capacitor. Maximum four numbers and units. Values can be from 25pf (8MHz clock, 50pF @ 1MHz clock) to 100mF. Resolution up to 1 pF (@ 8MHz clock). - Support two resistance measurements, the potential can be measured. If the potentiometer is adjusted to its end, the tester can not distinguish between the middle and the ends of the pin. - Resistance measurement resolution is 0.1 ohms, the maximum value of 50M ohms measurements. - measurement range from 25pf to 100mF (100000 ). Resolution up to 1 pF, inductance measurement range 0.01MH-20H, otherwise it will appear as a resistor, inductor DC resistance is higher than if Europe 2100 will also be displayed as a resistor. - It can detect 2 above capacitor equivalent series resistance ( ), a resolution of 0.01 ohms. This feature is very important for the detection of the capacitor performance. - It can display symbols of the two diodes in the right direction, also shows the forward voltage drop.
