SCS CTM051, Ground Pro Meter The SCS CTM051 Ground Pro Meter is a comprehensive instrument that measures the ground connection of your equipment in accordance with Grounding standard ANSI/ESD S6.1 and ANSI/ESD S20.20. In addition to measuring ground impedance, it also measures AC and DC voltage on the ground as well as the presence of high-frequency noise or electromagnetic interference (EMI) on the ground, alerting you to possible functionality problems, such as tool lockups, erratic behavior and parametric errors. Verifies Critical Grounding Parameters of a FacilityMeasures AC voltage, DC voltage, EMI voltage and AC impedance Provides Accurate Measurements of Ground Impedance on a Working ToolMeets ANSI/ESD S20.20 requirements for AC impedance Identifies Potential EOS GeneratorsMeasures maximum millivolt requirement of IPC-A-610 Auto-Zero Function for Test LeadsFactors out the impedance of the test leads for improved measurement accuracy Programmable Impedance AlarmAudible alarm sounds when impedance measurement is below threshold set by operator NIST Calibrated with Certificate IncludedCalibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology.
