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.
