Abstract
Official abstract text for this publication.
An apparatus and method for verifying the temperature compensation correction factor accuracy of an electrometer is provided. The electrometer includes an electrical amplifier to convert a current signal to a voltage signal. The electrometer also includes a compensation circuit to modify the voltage signal for temperature compensation. The electrometer further includes a heat producing device to induce a temperature change of the electrical amplifier and the compensation circuit. An environmental radiation monitor is also provided. The environmental radiation monitor includes a power supply, a high pressure ionization chamber, and the electrometer. The method includes providing an environmental radiation monitor, measuring the voltage signal at a first time, activating a heat producing device, measuring the voltage signal at a second time, and comparing the two measured values of the voltage signal.
