Multi Tester M328

Overview

The multi tester is one of the most popular devices for electronics enthusiasts, students or engineers. It allows you to detect component specifications very quick.

It can automatically detect NPN transistors, PNP bipolar transistors, MOS FET P and N transistors, JFETs, diodes, dual diodes and bidirectional diodes. Measures threshold voltage and gate capacity for MOS FETs. Measures threshold voltage and gate capacity for MOS FETs.

It can simultaneously measure two resistors and the resistance symbol is displayed. The decimal figures are displayed on the right side on 4 bits. A potentiometer can be measured. It can measure up to 50M ohms with a resolution of 0.1 ohms. Considering capacitors, the symbol is displayed on the right and the values ​​are displayed on 4 bits. It can be measured from 30pF to 100mF with 1pF resolution.
