LCR-T4 Digital Transistor Diode Inductance Multimeter With Test Hook

Digital multimeter with test hook

By FNIRSI

Features and specifications:

Key features: • 2013 latest M328 version with more functions • Ch: Atmega328 • 128 x 64 big balight LCD display, only 2 mA when on standby • Uses 9 V battery (not included) • Automatic detection of NPN and PNP transistors, n-channel and p-channel MOSFET, • diode (including double diode), thyristor, transistor, and and other components • Automatically test the pin of a component, and display on the LCD • Detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltage • Measure the gate and gate capacitance of the MOSFET threshold voltage Test ranges: • Inductors, s , diodes, dual diode, mos, transistor, SCR, regulator, LED tube, ESR, • resistance, adjustable potentiometer • Resistance: 0.1 ohm resolution, maximum 50M ohm • : 25pf -100,000 uf • Inductor: 0.01mh – 20H

Functions: • One-button operation, automatic shutdown • Only 20nA shutdown current • Automatically detect NPN, PNP bolar transistors , N -channel and P -channel MOS FET, • JFET, diodes, two diodes, thyristors small power unidirectional and bidirectional thyristor • Automatic identification components pin arrangement . • Measuring bolar transistor current amplification factor and base emitter threshold voltage • Emitter threshold voltage and high current amplification factor via the base to identify Darlington transistors • Can detect bolar transistors and MOS transistors protection diodes • Measuring the gate MOS FET threshold voltage and the gate capacitance • Can simultaneously measure two s and display symbol (Displayed on the right with a decimal value of 4. Resistance symbol on both sides shows the pin number, so you can measure the potentiometer. If the potentiometer wer is not transferred to an extreme position, • we can distinguish the middle and both ends of the pin) • Resistance measurement resolution is 0.1 ohms, 50M ohms can be measured • Can measure capacitance of 30pF - 100mF, resolution 1pF • 2uF more s can simultaneously measure the equivalent series resistance ESR values (Can be displayed with a decimal value, resolution 0.01 ohms) • Diode symbol display two diodes, and gives the diode forward voltage • LED is detected as a diode forward voltage (Combo of the LED is identified as two diodes) • Re breakdown voltage is le than 4.5 V (Zener diode can be identified) • Can measure a single diode re capacitance (If the bolar transistor connected to the base and collector or emitter of a pi, it can measure the collector or emitter junction re capacitance) • Can be obtained with a single measurement rectifier bridge connection Paage includes • 1 x Multimeter • 1 x hook set

Reminder: Before measuring capacitance, the must be discharged, otherwise it may damage the meter. The screen is not fixed.
