The reduction factor \( K \) of a tangent galvanometer is written on the instrument. The manual says that the current is obtained by multiplying this factor to \( \tan \theta \). The procedure works well at Bhuwaneshwar. Will the procedure work if the instrument is taken to Nepal? If there is some error, can it be corrected by correcting the manual or the instrument will have to be taken back to the factory?
