Review on MTester LCR-T4-H, Semiconductor Parts Tester by Janis Saikovskis ᠌

Identifies bipolar and field-effect (mos) transistors, diodes, zener diodes (for low-voltage zener diodes it measures the stabilization voltage), with an acceptable error (up to 5%) measures the resistance of resistors in the range from units of ohms to tens of megohms, capacitor capacitance within 10 pF - 22022 microf. It does not recognize germanium transistors, confuses composite transistors (not all) with thyristors, confuses field-effect transistors with a pn junction (2P103, KP302) with bipolar ones. Transistors with low h21e (less than 20 - KT209A, 2T301B, KT339A) are recognized as a pair of diodes. Tunnel diodes (3I306) are recognized as a pair of anti-parallel connected diodes. In general, an interesting toy.
