Position Range 
a 1 uf
b 100 nf
c 10 nf
d 1 nf
e 100 pf
Use X10 switch to measure up 10uf.
Use X0.5 switch for better readings on low values.

Its function is to charge the unknown capacitor (Cx) to a fixed voltage. The capacitor is then discharged into the meter circuit. The meter measures the current being drawn through the 47 ohm resistor.
