A. Descripon
The PED-718 ESD Event Detector is an easy-to-use hand-held device that is designed to detect and count
ESD events that can damage sensive components and cause tool lockups, errac behavior and paramet-
ric errors.
B. 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.
C. 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 (electromagnec interference) events, the PED-718 ESD Event Detec-
tor 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 PED-718 ESD Event Detector with 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 PED-718 ESD Event Detector detects most ESD events by the specific electromagnec signature these
events produce. Therefore, the performance of the PED-718 ESD Event Detector must be looked at in view
of wave propagaon. 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 praccal, considering necessary safety precauons, 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 conducve or even dissipave surface. When working with the automat-
ed equipment, always observe safety precauons as recommended by equipment manufacturer and your
company’s pracces.
D. General Operaon
When the PED-718 ESD Event Detector is turned on, it is ready to detect, count and measure most ESD
events.
E. Bar Graph Display
The 10-LED bar graph shows the relave strength of most ESD events. If an ESD event does not exceed the
set alarm level, LEDs indicang its strength are green. Whenever the strength of an event exceeds the set
threshold, LEDs turn red.
Event strength is a factor of many variables:
• The accumulated stac voltage
• The capacitance of the charged objects (a larger object holds more charge than a smaller one)
• The physical size of discharging objects
• The environment
• The distance from ESD event occurrence
Therefore, one should exercise good judgement in comparing the strength of ESD events captured under
different condions.
F. Threshold Adjustment
The PED-718 ESD Event Detector can detect ESD events in a wide dynamic range. For most applicaons,
only the events that exceed certain strengths are of importance. Threshold seng in the PED-718 ESD
Event Detector is crical in idenfying only ESD events of the strength equal or above the level of impor-
tance to you.

Threshold seng is done by a small rotary/push switch on the right side of the PED-718 ESD Event Detec-
tor.
G. Checking the Current Threshold
Simply push the actuator of the switch inwards. One red LED will show the current ESD event threshold.
Any event equal to or exceeding this level will produce a count and a beep, and the LED bar graph will
show it in red. An event below this level will sll be shown on the bar graph in green, but no count or
sound will be produced.
H. Seng the Threshold
To set a new threshold, do not press the switch. Rather, move its actuator up or down. Once the switch
begins to move, one red LED appears on the bar graph display. As the switch moves up and down, this red
LED moves accordingly and its posion indicates the new threshold level.
I. Saving the Threshold Level
Aer the new threshold is set, release the switch actuator and then press it inwards. The new current
threshold is now saved. The next me you power up your PED-718 ESD Event Detector, this level will be
automacally set.
J. Features and Components
Refer to the following pages of this User Manual for a detailed explanaon of each control, indicator and
connecon.
K. Controls and Indicators
• Power Switch: Turns power on and off
• Sound Switch: Turns the sound on and off
• Noise Filter Switch: Turns EMI-rejecon mode on and off
• Alarm Threshold: Adjusts alarm threshold up and down. Displays current alarm threshold. Resets
the Event Counter.
• Event Counter: Counts ESD events above the set threshold.
• ESD Event Strength Bar Grap: Displays relave ESD event strength. This graph is soley an indicator,
and it does not correspond to any unit of measurement.
• Filter Indicator: Shows that PED-718 ESD Event Detector is in filter mode (rejecon of EMI most
Events).
• Low Baery: Shows that the baery needs to be replaced.
L. Power
PED-718 ESD Event Detector uses a 9V alkaline baery. Do not use any other type of baery. If you are not
using your PED-718 ESD Event Detector for an extended period of me, remove the baery from the unit
in order to prevent damage caused by baery leakage.
M. Installing the Baery
Remove the baery door at the back of PED-718 ESD Event Detector and aach the 9V baery to the bat-
tery clips. Observe the polarity of the baery. Re-install the baery door.
N. Low-Baery Indicator
When baery voltage gets low, the low baery indicator on the display appears.
O. Turning PED-718 ESD Event Detector On and Off
Move the actuator of the power slide switch to the right. The ESD event counter should display a number
of captured events, usually “0” at this point. The events counter is reset when the power is turned off. To
turn the power off, move the actuator of power slide switch to the le. The PED-718 ESD Event Detector
has no automac shut-off. Don’t forget to turn it offwhen not in acve use.

P. Antenna
In order for the PED-718 ESD Event Detector to detect most ESD events, its antenna needs to be properly
installed. Screw the antenna using only your fingers—no tools since overghtening the connecon may
lead to damage to the instrument.
Q. Sound
The PED-718 ESD Event Detector can produce audible alarm when an event is deleted. In order to enable
this funcon, move the actuator of sound slide switch to the right.
R. Calibraon
The PED-718 ESD Event Detector is soley an indicator and not a meter. Its ESD Event Strength Bar Graph
only displays relave ESD event strength, and it does not correspond to any unit of measurement. Calibra-
on is not required.
