# Set Accelerometer Range
Set up the part of the micro:bit that measures
[acceleration](/reference/input/acceleration) (how much the microbit
is speeding up or slowing down), in case you need to measure high
or low acceleration.
```sig
input.setAccelerometerRange(AcceleratorRange.OneG);
```
### Parameters
* ``range`` means the biggest number of gravities of acceleration you
will be measuring (either `1g`, `2g`, `4g`, or `8g`). Any bigger numbers
will be ignored by your micro:bit, both when you are picking a
number of gravities, and when you are measuring acceleration.
### Example
This program says the highest acceleration that your micro:bit
will measure is 4G. Then it measures acceleration from side to side
until you stop the program.
```blocks
input.setAccelerometerRange(AcceleratorRange.FourG);
basic.forever(() => {
basic.showNumber(input.acceleration(Dimension.X));
});
```
#### ~hint
This program does not work in the simulator, only in a micro:bit.
