Is it possible to used same calibrated scale on the 3-V ranges as on the 300-V range of voltmeter?explain?

Question

it is about my laboratory class in circuits

Answer 1

when they are calibrating the voltmeters they are calibrating all the range selections that means when you are using a calibrated voltmeter and if the scale is suitable to measure 300 volts you can measure it. But you have to check the calibration certificate to check the fault % of the range if they are same "3 V and  300V" no problem.Ä°f not and if the measurement is so sensitive you have to calculate the fault ranges of the measurement.

Answer 2

Your question is incomplete, use it on what? to make measurements?

Do you mean you have a "calibrated scale" that you checked against a lab standard for one range? Calibration means checking the marks on the scale, the readings, against a reference standard. You don't make a new scale, you check the existing one for accuracy.
