WOLFGANG WARMBIER CPM374 Charge Plate

Description

The Wolfgang Warmbier CPM374 Charge Plate is a device designed to measure the effectiveness of air ionizers in neutralizing electrostatic discharge (ESD). Here’s a breakdown of its functionalities based on available information:

ESD Measurement:

• Air Ionizer Efficiency Testing: The CPM374 helps evaluate the performance of air ionizers used in ESD-protected environments (EPAs). Air ionizers neutralize static electricity buildup in the air, which can damage electronic components. By measuring the ionizer’s ability to dissipate charge, the CPM374 ensures it functions effectively.
• Electrostatic Decay Time Measurement: It likely measures the time it takes for a charged plate within the device to reach a specific voltage level (often 100V) after being charged to a higher voltage (typically 1000V). This decay time reflects the effectiveness of the surrounding air ionizer in neutralizing the charge.
• Compliance Testing: The CPM374 might be used to verify compliance with relevant ESD standards like ANSI ESD2020 or IEC 61340-2-1. These standards establish requirements for ESD control measures in workplaces handling electronic devices.

Additional Features (depending on model):

• Voltage Measurement: The CPM374 might possess built-in voltage measurement capabilities for the charge plate and potentially for external voltage sources (sold separately).
• Data Recording: Some models might offer data recording functionality to store and analyze measurement results for later reference or reporting.
• Analog Output: The device might provide an analog output signal corresponding to the measured voltage, allowing for integration with data acquisition systems for continuous monitoring.
