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.

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.
ESD Event Counting Mode:
Indicates that ESD event
counting is active.
Static Voltage Polarity:
Denotes the polarity of the
static voltage peaks.
Static Voltage Level Bar Graph:
Displays the current
change in static voltage field magnitude regardless of
polarity.
MAX:
Indicates the maximum magnitude of static
voltage within the last second duration.
PEAK:
Appears when the measured static voltage
exceeds the voltage range.
ESD Counter:
Counts the number events over the set
threshold. The maximum number is 1999 and resets to
0 once this limit is exceeded.
Static Voltage:
The current value of the signal being
measured by the antenna expressed in volts.
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.
