can we test ics with this like opamps are working fine or not
No, it does diodes, transistors, resistors and inductors.
do diodes.swap the ends and do it again. see the difference? no? exactly- complete junk.
I see what you mean. It correctly measures the diode but doesn't correctly identify which way around it is. A bit harsh to say it's complete junk though.
