An improved modulator assembly of an electrostatic voltmeter for an electrophotographic process. A modulator base of the modulator assembly having accurate configuration and built in design features which simplify manufacture and assembly of the modulator assembly and electrostatic voltmeter. The modulator base includes reference mounting surfaces which provide accurate orientation and alignment of the modulator assembly during assembly, air purge grooves which provide enhanced air purging of contaminants from the modulator assembly, and shielding areas which maximize the signal to noise. The modulator base provides simplified construction of a modulator assembly for an electrostatic voltmeter having enhanced performance and robust functionality.
