Xerox 600T442 Current Test Meter

The Xerox 600T442 Current Test Meter is a portable handheld diagnostic instrument for measuring low-current AC and DC values in Xerox xerographic printing and imaging systems. It supports 0–90 µA DC, 0–30 µA DC, and 0–90 µA AC ranges for diagnosing electrical circuits, calibrating imaging and charging assemblies, and evaluating charging current, corona output, and electrostatic system performance. As an analog microamp current meter, it includes a meter body with attached test leads (configuration dependent) and is used by Xerox field service technicians, maintenance personnel, and industrial print repair specialists in commercial and industrial print service environments. Common replacements include Xerox 600T441, 600T1616, and 600T23, and the unit is typically sold as a used or surplus instrument.
