It is the maximum voltage to which it has been calibrated, but this may be set out in separate ranges selected by a switch on the front panel.
Range: 5 Mean: 3
The mean is 3. The range is 4.
interquartile range or mean absolute deviation.
You need to have all the values within the range to calculate the arithmetic mean .
why is extention
If the voltage measured exceeds the voltmeter range then the voltmeter needle remains in it's maximum position until it's voltage values are considerably reduced.
With the pointer mid range on the scale, the reading of the multi-range voltmeter would be 125 volts.With the pointer mid range on the scale, the reading of the multi-range voltmeter is 125 volts.
if we would like to expand the range of voltmeter we should change the voltmeter resistance even to be appropriate . we should use a variable resistance to control of its value . I would extend the range of a voltmeter by adding resistance in series with it. I would extend the range of an ammeter by connecting resistance in paerallel with it.
Voltmeter connect in parallel with the circuit setting on voltmeter highest range first then to lower range. Ohmmeter we need to use the ohmmeter meter setting connect across the resistor
Multi-range ammeter using universal shunt
If the voltage is completely unknown, a voltmeter should be set to the maximum range first, then stepped down to an accurate level.
You mean fastest? Digital voltmeter gives reading in seconds.
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.
When you switch a voltmeter from a lower to a higher voltage range, an additional resistor is added in series with the meter, increasing the voltage necessary to create the same voltage drop across or current flow through the actual meter movement.
