FNIRSI DSO-TC3 Handheld Oscilloscope, Component Tester, Function Generator

The FNIRSI DSO-TC3 is a handheld Multitester Oscilloscope with 500kHz bandwidth and 10Ms/s sampling rate. It features a digital Oscilloscope, Function Generator, Component Tester and LCR Meter.

It is very compact and lightweight with low power consumption. It has a USB Type-C charging interface and a lithium battery. This oscilloscope has a high-resolution colour screen and minimalist keyboard design. A very handy multitester oscilloscope, function generator and component tester for the beginner, for fieldwork, and as a handy tester on your desk.

This model comes standard with a BNC-Alligator test probe. For x1x10 voltage scaling in your measurements, you will also need a BNC-MCX Adapter to use a standard oscilloscope probe with the DSO-TC3.

IMPORTANT: When testing capacitors with the Component Tester, you need to discharge the capacitor before inserting it into the test slots. If not discharged, you will damage the DSO-TC3 and this user error will void the warranty. Discharge capacitors by touching the 2 legs to each other before inserting them into the Component Tester slots. The warranty does not cover surge damage due to user error. Please carefully read the user manual and watch our Instruction videos.
