EM Eye - ESD Event Meter
Installation, Operation and Maintenance
Made in the
United States of America
Touch Screen to Power ON
The EM Eye Meter is designed with a modern user
interface. All buttons and controls are within the display
itself. With its display and touch screen, it is easier for
users to quickly navigate through the features that were
built into the meter.
Speaker and Headphone Alarm Outputs
The EM Eye Meter, with a speaker and headphones,
allows flexible means for audible indications, beeping
or “warbling” like a radio. If one is in a noisy place, a
headphone jack for optional headphones can be used
for clearer audio.

Description
The SCS EM Eye Meter is capable of providing
measurements for many various parameters, which
are determined by the type of sensor connected to the
EM Eye Meter. Below are the three sensors that are
available now:
•
ESD Events Detection
– The portable, easy-to-use
EM Eye Meter serves as a measuring instrument for
most ESD signals. The EM Eye Meter measures
the magnitude of ESD events. This meter also
estimates the events’ magnitude for CDM, HBM and
MM models.
Electromagnetic Field Measurement
– Enables
the EM Eye Meter to be transformed into an EMF
Meter, Power Density Meter and EIRP Meter.
RF Signal Sensor
– The EM Eye Meter measures
the amplitude of an RF signal.
Figure 2. Using the EM Eye Meter
Easy Data Logging to Memory Card
The EM Eye Meter supports data logging by using a
microSD card and exports to an Excel spreadsheet.
Having data at hand enables quick analysis. Solutions
can be decided quickly and can be measured on the
spot.

User Features
Modular Construction
The EM Eye Meter with the modular construction
concept can expand to different applications. With the
current design, it measures the magnitude of most ESD
events when in one of its filter modes, electromagnetic
fields (EMF), power density, effective isotropic ally
radiated power and radio frequency (RF).

Attaching the Antenna
In order to avoid damaging the EM Eye Meter,
installation and replacement of the antenna must be
done with great care. An excessive amount of force
or improper installation may permanently damage the
meter.
Attach the antenna to the input connector by simply
screwing it in by hand.
DO NOT OVERTIGHTEN THE CONNECTION. Screw
in the antenna firmly but gently. Do not use any tools
other than your hand to attach and detach the antenna.
Precautions
•
•
•
•
•
•
•
Do not drop the meter. This may damage the device
and will void the warranty.
Do not discharge directly into the antenna metals as
it may damage the input sensors and will void the
warranty.
Be cautious in the placement of antenna and the
module heads; align the parts while assembling.
Do not use sharp objects to touch the screen.
Do not use a wrench or pliers to screw or unscrew
the antenna. Use your bare hands.
Do not remove the microSD card while the power is
on. Turn off the meter before removing the microSD
card.
Do not remove the sensor heads while the power
is on. Turn off the meter before removing and
replacing the heads.

Power Supply and Charger
Use only the power supply that comes with the EM Eye
Meter. Do not use any other power supply as it may
damage the meter.
Battery Care - Charging for the first time
To improve the battery life we recommend that you
make three fully charge-discharge cycles. For example:
fully charge the meter for two hours or overnight,
then use the meter until it is fully discharged (do not
recharge it at half-charge-life). Repeat this step two
times. It would normally take two hours to fully charge
the battery, but since the meter power is on while
charging; it would extend the charge time to four hours.
Succeeding charging would be at any duration. Use only
the supplied charger.
Power On
Using your finger, press and hold any spot on the
screen for approximately three seconds – do not use
any tools to perform this action. If a new sensor was
installed, a sequence of initialization will take place
for the first time for approximately ten seconds. After
that, the switch-on action will take approximately three
seconds. The main display screen appears after the
initialization and a beep will sound. The EM Eye Meter
will then perform a battery check. If the battery is too
low to provide reliable operation, it will not turn on. The
screen will go white momentarily and then the meter will
power up. After the initial power up, the meter will go
directly to the main screen.

Modular Assembly and Disassembly
1. Position the sensor head so that the dowel pins
align with the holes.
2. With the initial head midway through, reposition it so
that it is parallel to the body. Press the sensor head
firmly against the body until both surfaces are flat
with each other.
3. Insert and screw in the antenna making sure that it’s
not too tight or too loose. Do not use any tools other
than your hand. NOTE: Antenna is not applicable
for the RF Signal Sensor.

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.
HBM Mode
In IC testing, operators
that are handling an IC
(i.e. fixing bent leads) may
be discharging through
the IC.
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.
Raw Input Mode
For engineers who want
to simply analyze raw
ESD signals for further
analysis, the Raw Input
mode provides actual
voltages received by an
antenna.
CDM 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.
MM Mode
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
affect nearby products or
instruments
In using a bad soldering
iron, induced voltages
may cause discharges to
the components mounted
into the PCB. Use ground-
ed tools and confirm that
no ESD events will be
detected by using the MM
mode.
In feeder bowls where the
ICs are arranged for sort-
ing or orientation, voltages
may be induced by the
vibrating bowl.
