Pegging the gauge. Pegged out. Maximum measurement...and then some.

For example... When my geiger counter started screaming and the needle pegged out on all settings, past time to run like the wind out of this radioactive hell hole.

Or it might refer to a zero measurement that has increased just a tad...or a smidgeon.

Just depends on how much the needle moves. Ever turn an air conditioner down in summer or a heater up in winter? Then you have moved the needle on a thermostat.
