Overall Features

The 3M™ EM Eye Meter is a universal instrument that is capable of providing measurements for many various parameters, which are determined by the type of sensor connected to the EM Eye Meter. Below are the three sensors that are available now:

•ESD Events Detection – The EM Eye Meter is capable of detecting ESD events of most testing models, specifically focusing on the CDM model. It is easy to operate and can be used by almost anyone who is involved with ESD. The EM Eye Meter provides information on estimated discharge voltages at a specific location, what time the event occurred and how many discharges have occurred. The meter’s size is so small it can be used in tight locations inside a tool or in a wider area of interest. For extended temperature environments, the EM Eye Meter can use an optional special remote antenna which will work in most conditions. All information is recorded on miniSD™ card for easy review and retrieval of data.

•Electromagnetic Field Measurement – By simply placing the Electromagnetic Field (EMF) sensor head into the EM Eye Meter base, the EM Eye Meter transforms into a dedicated EMF meter, a power density meter and an EIRP meter. The EM Eye Meter detects and measures high frequency electric fields that may be present in equipment, tools, circuit boards or on any process in a manufacturing area. The EM Eye Meter also measures high frequency electric fields from mobile phones, over-the-air TV signals, wireless LANs and any other source generating fields within its specification. The EM Eye Meter comes with a miniature directional antenna that measures various field parameters. The directional antenna reduces the influence of ambient electromagnetic fields when measuring emission coming from the specific source. So whether you’re in the fields of product design, mobile phones, TV signals or wireless LANs, the portable EM Eye Meter is an important part of your toolbox.

•RF Signal Sensor – The EM Eye Meter with the replacement RF Sensor head is capable of measuring RF signals. Usually used by radio communications designers and engineers, the EM Eye Meter will be able to provide a readout of RF signal voltages. The EM Eye Meter offers exceptional sensitivity and linearity.

User Features

Modular Construction

The 3M™ EM Eye Meter with the modular construction concept can expand to different applications. With the current design, it measures ESD events, electromagnetic fields (EMF), power density, effective isotropically radiated power and radio frequency (RF).

Touch Screen to Power ON

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.

Speaker and Headphone Alarm Outputs

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.

Remote or Local Antenna Selection

3M recognizes that an engineer may be working in tight physical locations. The EM Eye Meter is small and portable with expansion accessories that can be fitted in hard-to- reach places, and in hot or cold temperatures.

Easy Data Logging to Memory Card

The EM Eye Meter supports data logging by using a miniSD™ 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.

Box Contents

Please confirm that the following accessories are included in your 3M™ EM Eye Meter package when you open it:

•Base EM Eye Meter module

•One or more of the following sensors heads:

•ESD event sensor with antenna

•Electromagnetic field sensor with antenna

•RF signal sensor (includes RF cable and 20 dB attenuator)

•Power supply adapter

•Optional accessories may be ordered separately:

•Remote antenna CTC113; CTC115 (extended temperature)

Serial Number

The serial number of your meter is a 5-digit number located at the top left section of the Menu F screen.

Precautions

•Do not drop the meter. This may damage the instrument 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 miniSD™ card while the power is on. Turn off the meter before removing the miniSD 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

Please keep in mind the following when using the modular sensor heads.

BEFORE CONNECTING TO AN INPUT SOURCE, TOUCH THE OUTSIDE SURFACE OF THE 3M™ EM EYE METER INPUT CONNECTOR. THIS WILL HELP PREVENT ESD SHOCK TO THE METER.

1.The power must be turned off when changing the sensor heads.

2.Make sure to gently plug or unplug the sensor heads.

3.Plug or unplug the sensor heads by gripping them firmly balanced on each side. Do not use the antenna for plugging and unplugging the sensor heads.

4.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.

9

Power Supply and Charger

Use only the power supply that comes with the 3M™ EM Eye Meter. Do not use any other power supply as it may damage the meter.

Battery Care

Charging for the first time

To improve the battery life we recommend that you make 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

Using your finger, press and hold any spot on the screen for approximately three seconds – do not use any tools to perform this action. 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.
