SCS ESD Pro – ESD Event Indicator (CTM082)

• ESD event indicator – detects and counts ESD events
• Four digit counter displays ESD events above the set threshold
• CDM filter switch – filters and rejects EMI signals not caused by CDM discharges
• 10 LED bar graph shows the relative strength of the ESD event
• Portable operation with a 9V battery 

The CTM082 ESD Pro – ESD Event Indicator is an easy-to-use hand-held device that is designed to detect and count ESD events that can damage sensitive components and cause tool lockups, erratic behavior, and parametric errors.

Event Counter – A four-digit display counts the number of events equal to or exceeding the threshold. To reset the counter, press the actuator of the ‘Set’ side switch inwards. The counter is also reset when the power is turned off.

Noise Filter – In a typical industrial environment, there are many sources that produce signals similar to those of ESD events. Such signals may include relays, solenoids, stepper motors, or similar devices. In order to separate ESD events from non-related EMI (electromagnetic interference) events, the ESD Pro – ESD Event Indicator employs a filter that separates waveforms of the signals and rejects the ones that are different from a ‘classic’ shape of an ESD event. First, try to use the ESD Pro – ESD Event Indicator with the Noise Filter switch turned off. This allows you to assess the complete environment. If you observe extraneous events, then turn the Noise Filter switch on.

The ESD Pro – ESD Event Indicator detects most ESD events by the specific electromagnetic signature these events produce. Therefore, the performance of the ESD Pro – ESD Event Indicator must be looked at in view of wave propagation. Just like with a microphone, the farther away from the source of the signal you are, the weaker the signal will be. When searching for the sources of ESD events, it is advisable to get as close as is practical, considering necessary safety precautions, to the suspected sources. In a typical tool, such as an IC handler or a pick-and-place SMT machine, such sources of ESD events may include places of IC pick-up and IC placement on any conductive or even dissipative surface. When working with automated equipment, always observe safety precautions as recommended by the equipment manufacturer and your company’s practices.

• 10 LED Bar graph display – Shows the relative strength of the ESD event
• Adjustable alarm threshold – Use the rotary switch to set the strength for which the ESD event must meet in order to be counted
• Four digit counter – Displays the number of ESD events that occurred at or above the alarm threshold
• CDM filter switch – Filters and rejects EMI signals that are not caused by Charged Device Model discharges
• Portable operation with 9V battery – No charging or sourcing of special batteries needed
• Assembled in the USA with globally sourced materials
