... There is no direct measurement of capacitance on that particular meter.
And think twice where the red plug is inserted before you try to measure DC current.
A DC current in excess of 200 ma will blow a fuse ... when the red plug is in the right DC amp jack ... that fuse must be replaced inside the case. ... If the Red plug is in the left DC amp jack, a DC current in excess if 10 amps may cause permanent damage.
The hfe pin holes are for finding a transistor current gain parameter, used to design transistor circuits.

Thanks alot... will have to buy a new multimeter

Since you already have a multimeter you may want to consider what is called a LCR meter that measures inductors as well as capacitors. Here is a handy one that is very popular and inexpensive. Not super precise but good for practical use. This is just a typical and can be found for much less. Very handy to have around.

The "µ" symbol is called the "Mu". It represents micro, meaning on the order of six decimal places. 1µA = 0.000,001 Amp. so 200µ would mean 0.0002A.
2m = 2 "Micro" amps. Or 0.002A
20m = 0.02A
200m = 0.2A
10A = 10 amps.

You would use the 10A to measure amperage UP-TO 10 amps but not exceeding that. Doing so would damage the meter if it is not internally fused. That meter says the 10A is not fused. The 200m (0.2A) has a fuse at 200mA and exceeding that amperage would blow that fuse. The 20m and 2m are for measuring amperage in the very low ranges with fairly accurate measurements. If you exceed the 20m the meter should just say "OL" Over Limit or something like that. As long as you do not exceed 200mA you won't blow the fuse; just the meter won't give you a reading on - say - 30mA on the 20m setting.

... correction ... The 200 ma mark is the most DC current to be measured using the red plug inserted into the rightmost jack. ... Not the previously stated 2m green label.

The #1 newcomer mistake in using a DMM (digital multimeter) is blowing the fuse or worse, destroying the meter.

Rule #1 Always return the meter range to the highest voltage measurement setting AND put the probes in the COM and V jacks.
Rule #2A Don't change range setting while the probes are still touching the circuit.
Rule #2B Don't switch from V to A or A to V while the probes are in circuit (same as Rule #2A).
Rule #3 You cannot measure current across a circuit. You must break the circuit and then insert the meter in series after setting to current measurement mode.
Rule #4 Start at the highest range scale if you are unsure of the expected range then move to a lower range if necessary. Follow Rule #2.

Why do you need to measure capacitance? Are you using capacitors that are not marked with their capacitance?
Do you have Oriental capacitors marked "102, 103 or 104" which is 0.001uF, 0.01uF or 0.1uF?
Do you have a huge very old electrolytic capacitor that might have dried up?

My multimeter cannot measure capacitances less than 200pF because that is the capacitance between its leads.

Usually a defective capacitor wrongly conducts then it has resistance or is shorted. It must be disconnected from a circuit for you to measure resistance. Caution: it might be charged so discharge it first.
