Ground Pro Meter for ground impedance and EOS source testing - Desco CTM051

The Ground Pro Meter CTM051 verifies the critical grounding parameters of an EPA and reveals potential EOS sources before they damage sensitive components. This handheld instrument combines four measurement functions and is built for audits to ANSI/ESD S20.20.

Benefits

• Measures AC impedance on live workstations and tools and meets the ANSI/ESD S20.20 requirements
• Identifies EOS sources by measuring the maximum millivolt requirement of IPC-A-610
• Auto-zero function factors out the impedance of the test leads for improved accuracy
• Programmable impedance alarm sounds an audible warning when the reading drops below the set threshold

Technical specifications

• Measured values: AC voltage, DC voltage, EMI voltage, AC impedance
• AC voltage (50 to 500 Hz): 0.001 to 250 V RMS
• Impedance: 0.000 to 1999 ohm across four ranges
• EMI bandwidth: 9 kHz to 450 MHz, 10 mV to 5 V peak
• Calibration: NIST traceable, certificate included
• Weight: approx. 0.59 kg

Applications

The CTM051 is used for routine audits of ESD workstations, verification of grounding points on tools and machines, and troubleshooting of electrostatic and electrical noise sources in electronics manufacturing.

Standards and compliance

Meets the AC impedance requirements of ANSI/ESD S20.20 and supports testing under IEC 61340-5-1.
