Very nice device 3 in one. A+++
A
1. Take an electrolytic capacitor (e. g. 100 μF) and test it on the component tester.
2. Connect a low Ohm resistor (5..10 Ohm) in SERIES to the same capacitor and test again.
On my TC3:
220 μF 63 V Samwha SD: 209.2 μF 0.08 Ohm.
The same capacitor + 8.98 Ohm 0.5% resistor: 211.3 μF 1.2 Ohm (!!!). How on Earth?
On an old ATmega based component tester:
The same capacitor itself: 206.1 μF 0.19 Ohm.
With the resistor: 208.0 μF 8.49 Ohm. Slightly low (the correct value should be around 9.1 Ohm), but still reasonably close to truth.
The resistor itself displays 9.0 Ohm on BOTH TC3 and the old tester.
E
Little Offset from in terms of Ampli & Freq in Generator Mode. Some minor issues in Part -detecting Mode. Scope Mode better than expected ( in terms of 3dB Bandwidth) !
Usable 4 Audio & Test of slow AD / DA systems.
