Range: ±3000 volts, auto polarity.
Accuracy:* 0.1%, ±0.003%/°C over +20 to +40°C
range (at recorder output). Useable to +50°C.
Speed of response:*
For typical input step: <3ms (10% to 90%)
for 1kV step: <2½ms (10% to 90%)
for 2kV step: <3½ms (10% to 90%)
for 3kV step: <4ms (10% to 90%)
Surface resolution: Determined by probe aperture size
and surface-probe separation.Standard type 1017AE & AS probes with 0.07” (1.75mm) aperture will resolve a 0.10” (2.5mm) spot at 0.02” (0.5mm) separation.
Recorder output: Compressed analog output is input
divided by 1000 (optional Model 244AK has divide by 200) for external
loads greater than 1KΩ. Output connector is BNC.

The 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.
