why we connect voltmeter in parallel with series connection of diode and ammeter for reverse biasing

Not clear. Can you post a sketch?

Question: What are the significance of readings you get from those metres in the mentioned configurations? Or what do the readings mean?

Sir my question was based on the lab experiment that i did last day.we were instructed to plot the voltage vs current characteristics of p-n junction diode for both forward and reverse biasing.the circuit connection is different in reverse biasing not in terms of the diode but in terms of the connection of voltmeter which is in parallel with a series connection of the diode and ammeter .this in contrary to the connection of voltmeter in forward biasing which is connected in parallel across the diode only.
And Iam so sorry that i have got the answer and it explains that because in reverse bias the value of current is in the order of microamperes .so if we connect the ammeter in parallel across the diode only the current read by the ammeter will be even small because there will be division of current in parallel circuit.And a lot lot of thanks for responding to my simple question.
