Description
The SCS EM Aware Monitor monitors up to three key
parameters that keep you aware of critical symptoms
of ESD problems: ESD events, change in static voltage
field, and ionizer performance*. The thresholds for
these parameters are fully adjustable. The monitor is
constructed of an aluminum enclosure, LCD display,
control joystick, remote antenna, power adapter and
data output terminal.
ESD events generate electromagnetic radiation.
The stronger the ESD event, the stronger the
electromagnetic radiation. The EM Aware Monitor is a
miniature radio receiver tuned to detect and measure
the unique waveform generated by an ESD event.
The EM Aware Monitor meets the Continuous Monitor
requirements of ANSI/ESD S20.20 in accordance with
ESD TR1.0-01 and ANSI/ESD STM3.1. It meets the
recommendations of ESD Handbook ESD TR20.20
which includes “if the products that are being produced
are of such value that knowledge of a continuous,
reliable ground is needed, and then continuous
monitoring should be considered or even required”.
*Ionization monitoring is only available in item
CTC034-031-5-WW. Compatible with critical
environment ionizers only. The ionizer must have a
balance (offset voltage) of ±5V or better.

1. Remove the monitor and antenna from the carton
and inspect for damage.
2. Determine the installation location of the antenna.
For optimal performance, position the antenna
as close as practically possible to the anticipated
source of ESD activity. Use the mounting tabs on
the antenna to properly secure it to the desired
location.
3. Connect the anntena’s cable to the EM Aware
Monitor without bending it.
4. Determine the mounting location of the monitor. Its
display should be visible to the operator. Use the
two 4-40 threaded holes at the back of its enclosure
if desired.
5. Secure one end of the included ground cord to
the ground terminal located on the right-side of
the monitor. Attach the other end of the cord to a
ground point. The face plate screw of a grounded
AC wall outlet may provide a convenient connection
point.
6. Connect the power adapter to the power jack
located on the right-side of the monitor. Route the
wire from the supply to a nearby AC outlet and
plug it into the outlet. Make sure the voltage and
frequency match those listed on the power supply.
The monitor is now powered.

Operation
Controlling the EM Aware Monitor
The EM Aware Monitor is controlled using a 5-position
joystick located to the right of its display. The joystick
can be toggled left, right, up, and down and pushed
inward.
The EM Aware Monitor will default to the ESD Event
display upon completion of its boot-up sequence.
Toggling the joystick left, right, up and down all serve
the same function and advance the display to the next
channel. See Figure 5.
Push down and hold the joystick for 3 seconds to enter
the displayed settings.

the antenna which is a result of an ESD event near the
antenna. It is measured in dBµV.

1. Toggle the joystick until the ESD Event channel is
displayed (Figure 6).
2. To reset the ESD counter to zero, push down the
joystick momentarily.

3. To change the ESD threshold, push down and hold
the joystick until “ESD” is displayed. The “REF”
indicator will appear on the top-left corner of the
display to indicate that the ESD threshold value can
be modified. Toggle the joystick left to decrease
the threshold. Toggle the joystick right to increase
the threshold. Hold the joystick in either direction to
quickly increment the value.

4. When the noise filter is enabled, the EM Aware will
detect mostly ESD events and ignore other signals
such as EMI. If the noise filter is disabled, all signal
types will be detected. To disable or enable the
noise filter, enter the ESD threshold settings as
described in the previous step, and then toggle the
joystick up or down. “Cdr OFF” indicates that the
filter is disabled, and “Cdr On” indicates that the
filter is enabled.

measured by the antenna expressed in volts.

5. Push down the joystick momentarily to save all
settings. “MEM” will appear temporarily in the
top left corner while the settings are saved. The
monitor will then re-boot after the save is completed.
NOTE: The monitor will revert back to its last saved
settings if idled for 10 seconds while in the settings
menu. The joystick must be pushed down in order
to save all modifications to the settings.
Static Voltage Threshold Marker:
Marks the static
voltage threshold setting.
Principle of Operation of Static Voltage
Monitor
The Static Voltage channel measures the change of
electrostatic field. Any change in electrostatic field
induces voltage on the antenna via capacitive coupling.
An electrostatic field that is stationary does not induce
voltage on the antenna, so the EM Aware will show a
decreasing value.
Indication of Static Voltage
The Static Voltage Level Bar Graph in the bottom left
corner of the display indicates absolute magnitude of
static voltage regardless of polarity. An audible alarm
will sound when voltage of any polarity exceeds the
preset alarm level.

Static Voltage Settings
1. Toggle the joystick until the Static Voltage channel
is displayed (Figure 9).
2. To reset the ESD counter to zero, push down the
joystick momentarily.
3. To change the voltage range and thresholds, push
down and hold the joystick until “REF” is displayed
on the top-left corner. “REF” indicates that the
settings can be modified.
4. Toggle the joystick up or down to scroll through the
voltage range options (12.5, 100, 250, 500, 1000
volts). Select the 12.5 volt range to enable the
ionization balance function if desired.
NOTE: The ionization balance function is only
available in the CTC034-031-5-WW model.
5. Toggle the joystick left to decrease the threshold.
Toggle the joystick right to increase the threshold.
Hold the joystick in either direction to quickly
increment the value.
6. Push down the joystick momentarily to save all
settings. “MEM” will appear temporarily in the
top left corner while the settings are saved. The
monitor will then re-boot after the save is completed.
NOTE: The monitor will revert back to its last saved
settings if idled for 10 seconds while in the settings
menu. The joystick must be pushed down in order
to save all modifications to the settings.
Ionization Balance Threshold Marker:
Marks the
balance (offset voltage) threshold setting.
NOTE: The EM Aware Monitor is compatible with
steady-state DC critical environment ionizers only. The
ionizer must have a balance (offset voltage) of ±5V or
better.
Ionization Balance and Decay Settings
NOTE: These settings cannot be changed unless the
static voltage range is set to 12.5 volts. See “Static
Voltage Settings” on page 4.
1. Toggle the joystick until the Ionization Balance and
Decay channel are displayed (Figure 10).
2. Push down the joystick momentarily to manually
measure the ionizer’s balance (offset voltage) and
decay time. The
*-
symbols will appear while
the measurements are being taken. The balance
(upper row) and decay time (lower row) will update
at the end of the tests. Balance and decay time are
automatically measured every three minutes. Static
voltage monitoring becomes idle when balance and
decay tests are performed. ESD event monitoring
operates normally.
3. To change the voltage range and thresholds, push
down and hold the joystick until “REF” is displayed
on the top-left corner. “REF” indicates that the
settings can be modified. The value in the top row
indicates the current balance threshold, and the
value in the bottom row indicates the decay time
threshold.
4. Toggle the joystick down to decrease the decay
time threshold. Toggle the joystick up to increase
the decay time threshold. Hold the joystick in either
direction to quickly increment the value.
