Answer:
Zero error.
Explanation:
When the pointers of the voltmeter or ammeter does not coincide withe the zero mark on the scale then the error is known as zero error. Now if there is a zero error on the device then the error must be subtracted from the reading to get the perfect result.
The error value must be deducted from the observed value when there is no current in the circuit.
