Do you mean the pressure gauge?
That's fairly normal. The heating circuit is normally filled to around 1.1 - 1.3 bar cold, and will rise when the heating is on anything up to 0.8 bar above the cold fill pressure.
If the pressure gets too high, the boiler will lock out on a safety. (Normally around 3 bar)
Sounds like nothing to worry about....
