The 3M

ESD Pro is easy-to-use hand-held indicator and counter of 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.

CDM Mode

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 and alike. In order to separate charge-device type

events from non-related EMI (electromagnetic interference) events, 3M

ESD

™

Pro employs a patent-pending system that analyzes waveforms of the signals

and rejects the ones that are different from a "classic" shape of an ESD

event. More specifically, CDM (charged device model) waveform is set as a

template.

In order not to miss ESD events, in case of the questional waveform that has

a possibility of being a legitimate ESD event, the 3M

ESD Pro registers the

™

event as an ESD event leaving the user to make a determination.

First, try to use the 3M

ESD Pro with CDM mode turned off. This allows

™

you to assess the complete environment. If you observe extraneous events,

then the turn CDM mode on.
