My digital multi-meter v88C has a problem with measuring capacitance and inductance , mybe I connected a charged Cap to it...

1. I need to know about main DMM chip number, as you can see in the picture it is like nothing....
2. I need to know how a DMM measure capacitance and inductance, I found out there is a TL062C with triangle wave around 200hz and pin 3 of it connected to one of the prob with 1k resistor ( when selector is on 2uf range).
