ESD Event Detection Sensor
The SCS EM Eye Meter will help you detect most ESD
events. This will help you make sound decisions in
tackling what may have been a daunting task. The EM
Eye Meter detects the magnitude of events and using
the filters built into the unit. It can provide approximate
values for some ESD Events for models (CDM, MM,
HBM) using proprietary algorithms. Switching between
any of the modes will give you immediate data analysis.
Solving ESD problems requires data; a before-and-after
analysis of data may now be measured and used to
tailor ESD control programs.
CDM Mode MM Mode
In IC testing, ICs that are
sliding through tubes may
be charged up. Once the
lead touches the metal
tracks, a CDM event can
occur.
A moving, ungrounded
cart may accumulate
charges in its path. As
it approaches a metallic
worktable and bumps
into it, a discharge may
occur and may adversely
aect nearby products or
instruments
In feeder bowls where the
ICs are arranged for sort-
ing or orientation, voltages
may be induced by the
vibrating bowl.
In using a bad soldering
iron, induced voltages
may cause discharges to
the components mounted
into the PCB. Use ground-
ed tools and conrm that
no ESD events will be
detected by using the MM
mode.
HBM Mode Raw Input Mode
In IC testing, operators
that are handling an IC
(i.e. xing bent leads) may
be discharging through
the IC.
For engineers who want
to simply analyze raw
ESD signals for further
analysis, the Raw Input
mode provides actual
voltages received by an
antenna.
During picking up of an IC
by a person not properly
wearing a wrist strap, use
the EM Eye Meter to
alarm the operator of such
events.

ESD Events Sensor - Display and
Controls
For the detection of most ESD events using CDM, MM
or HBM models.
Common Display and Controls
POWER and CLEAR
The POWER C button turns off the SCS EM Eye Meter
or clears the values that are on display.
To turn off the meter, press and hold the POWER C
button for approximately four seconds or longer until the
meter goes off.
To reset all of the values on the display, press the
POWER C button for approximately one second.
Figure 8. ESD Event Sensor displays and controls
Figure 9. Using the Power / Clear button
HOLD and MAX
The HOLD button toggles the HOLD data and MAX data
sequentially.
HOLD freezes the current data on the display. The
instrument will not be active at this point.
MAX displays the maximum voltages detected by the
EM Eye Meter above the set threshold.
Pressing the HOLD button for the third time will disable
the HOLD and MAX function and returns to normal run
mode.
HOLD and MAX does not affect recording into memory
storage. Data is still being recorded even if HOLD and
MAX is active.
Figure 10. Using the Hold button
TIME
To set the time, press the battery icon.
The NAVIGATOR screen appears.
Press the left or right arrows to move the shaded area
that need to be changed.
Press the up or down button to scroll and set the
numbers.
Press the center button to return to the main screen.
Time: AM/PM format or 24-hour format
Date: Format as MM/DD/YY
Mode: 12-hour, 24-hour format

Audio Indicators
The AUDIO INDICATOR button scrolls through the
following audio modes:
1) Tone (bell)
2) Speaker at low volume
3) Speaker at middle volume
4) Speaker at loud volume
5) Mute
The BELL audio mode sends an audible beep for every
ESD event count detected. The SPEAKER, on the other
hand, produces the “crackling” or “humming” amplitude
de-modulated sounds of ESD event or EMF. This may
provide a better feel of what discharges or EMF sounds
like. The MUTE disables the audio and the unit operates
in silent mode.
Battery
The BATTERY symbol displays the approximate level of
battery life remaining for use.
Full charge life.
Half charge
<1 hour charge, charging is required
Battery is discharged, charging is required
