Least count
Max value of ammeter or voltmeter/ no. of divisions
Zero error
If the pointer of the ammeter or voltmeter is exactly at zero, when it is not connected to the circuit, then the instrument has zero error.
If the pointer is above the zero mark, the the zero error is negative.
The number of divisions it is above the zero mark are to be subtracted from the reading
