EM Eye – ESD Event Meter
Installation, Operation, and Maintenance
Description
The SCS EM Eye – ESD Event Meter detects, counts and measures ESD events that can damage ESD items and cause tool lock-ups, erratic behavior, and parametric errors. It calculates event magnitude for Charged Device Model (CDM), Human Body Model (HBM), and Machine Model (MM). All measurements are recorded onto a microSD card for PC download. It features a touchscreen display and rechargeable lithium ion battery. Each EM Eye – ESD Event Meter is calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology (NIST).
Resistive Touchscreen
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.
Data Logging
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.
Speaker & Headphone Audio
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.
The EM Eye Meter and its accessories are available as the following item numbers:

- 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.
Attaching the Sensor Heads
Keep in mind the following when using the modular sensor heads.
BEFORE CONNECTING TO AN INPUT SOURCE, TOUCH THE OUTSIDE SURFACE OF THE EM EYE METER INPUT CONNECTOR. THIS WILL HELP PREVENT ESD SHOCK TO THE METER.
- The power must be turned off when changing the sensor heads.
- Make sure to gently plug or unplug EM Eye Meter and the sensor heads.
- Plug or unplug the sensor heads by firmly gripping them. Then fit the sensor over the EM Eye unit. Do not grab the antenna for plugging and unplugging the sensor heads.
- If the antenna is separated from the sensor head, reattach it when the sensor head is securely in place.
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.
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
NOTE: The power switch must be in the ON position when charging the battery. To improve the battery life we recommend performing 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
Use the slide switch at the bottom of the meter to power the device. 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.
Features and Components
Modular Assembly and Disassembly
- Position the sensor head so that the dowel pins align with the holes.
- 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.
- Insert and screw in the antenna making sure that it is not too tight or too loose. Do not use any tools.

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.
| CDM Mode | MM 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. | 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 feeder bowls where the ICs are arranged for sort- ing or orientation, voltages may be induced by the vibrating bowl. | 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. |
| HBM Mode | Raw Input Mode |
| In IC testing, operators that are handling an IC (i.e. fixing bent leads) may be discharging through the IC. | For engineers who want to simply analyze raw ESD signals for further analysis, the Raw Input mode provides actual voltages received by an antenna. |
| 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. |
