ESD FILTER MODELS*
*Not all ESD events are captured by
the 3M™ EM Eye Meter CTM048. The
magnitude of the event can be measured.
CDM, HBM and MM Model results are
estimated based on proprietary algorithms.
ESD THRESHOLD
“TRUE-ESD FILTER” and “ALL-SIGNAL”
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
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 - 999mV for RAW input
After pressing the lightning bolt symbol or the TRUE-
ESD-FILTER button, the triangle button appears on the
display. In this mode, the 3M
™
EM Eye Meter CTM048
will detect most signals, including ESD and some EMI
signals.
After pressing the triangle or the ALL-SIGNAL button,
the lightning bolt symbols appears on the display. In
this mode, the EM Eye Meter CTM048 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.
