Model 244AL is a Model 244A ISOPROBE® Electrostatic Voltmeter with its measurement range reduced to make precision high-speed, low-noise electrostatic measurements in the range of ±15 volts. This range reduction enables the instrument to resolve 10 mV on the surface. Front panel zero and balance controls elminate zero shift with spacing changes.
