ESD Filter Models*
The ESD MODE button enables the user to choose
between RAW INPUT and calculations of HBM, MM and
CDM.
At the NAVIGATOR button:
Press the up/down arrows to set the distance.
Press the left or right arrows to set ESD event models.
Press the center button to return to main screen.
Effective distance range
0.5" (1.3 cm) to 15.0" (38.1 cm)
Filter
1. Human Body Model (HBM)
2. Machine Model (MM)
3. Charge Device Model (CDM)
4. Raw input
*NOTE: Not all ESD events are captured by the EM Eye
Meter. The magnitude of the event can be measured.
CDM, HBM and MM Model results are estimated based
on proprietary algorithms.
“True-ESD Filter” and “All Signal”
After pressing the lightning bolt symbol or the TRUE
ESD FILTER button, the triangle button appears on the
display. In this mode, the EM Eye Meter will detect most
signals, including ESD and some EMI signals.

ESD Threshold
The THRESHOLD, in a form of an ARC LED bar,
displays the detection level of the ESD events detected.
When pressed, the threshold level may be adjusted.
With the NAVIGATOR bar:
Press the left or right arrows to set the ESD event
threshold voltage. Press the center button to return to
the main screen.
Threshold Levels
0 - 10 Volts at 1V increments
10 - 990 Volts at 10V increments
1 - 1,500mV for RAW input
After pressing the triangle or the ALL SIGNAL button,
the lightning bolt symbols appears on the display. In this
mode, the EM Eye Meter will detect ESD events that
are mostly CDM in nature. Not all events are captured
and the information provided is based on proprietary
algorithm which models and approximates for the event
type.
Data Storage and Read
The DATA STORAGE button displays the data stored
in the microSD card found at the bottom of the EM Eye
Meter.
Scroll through the recorded data using the NAVIGATOR
button.
The displayed information is as follows:
(ESD mode) (Threshold) (Distance) (CDM on/off) (Date)
(Voltage sensed) (Time) (Data bar indicator)
Data from the microSD card can be exported using the
utility software described in the following section.
