HERE IS YOUR ANSWER. ..
Least count for a measuring instrument means the smallest value that can be measured using the instrument. This can be calculated by dividing the maximum value that can be measured using the instrument by total number of divisions on the scale. Least count gives the resolution of the instrument.
Ammeter or Voltmeter is said to have zero error if their pointer doesn’t read zero when it is supposed to read i.e. when not connected to the circuit.
Before making connections, this zero error needs to be noted, if any. After connecting the meters to the circuit and upon measurement, this zero error needs to be accordingly added to or subtracted from the shown reading to get the actual reading.
Similar to least count, zero error is also applicable to other measurement devices.

Answer:
⭕️If the indicator hand is beyond the 0, then the zero error is called -ve zero error and the no.of divisions must be subtracted from the final reading. ⭕️Least count is the lowest possible measurement possible by a device.
