Safety Information

Please read, understand, and follow all safety information contained in this

User’s Guide prior to use of the 3M™EM Eye Meter CTM048. Retain these

instructions for future reference.

Explanation of Signal Word Consequences

WARNING Indicates a potentially hazardous situation, which, if not avoided, could

result in death or serious injury and/or property damage.

CAUTION Indicates a potentially hazardous situation, which, if not avoided, may

result in minor or moderate injury and/or property damage.

To reduce the risks associated with hazardous voltage, which if not avoided, could result in death or

serious injury:

• Never allow children or other non-qualiﬁed persons to come in contact with battery charger;

• Never use battery charger outdoors or in other wet locations;

• Always use extreme caution to avoid coming into contact with any exposed electrical conductors of

the equipment being measured with the 3M™EM Eye Meter CTM048.

To reduce the risks associated with hazardous voltage or possible ﬁre or explosion related to internal

Li-ion battery, which if not avoided, could result in death or serious injury:

• Use only the battery charger provided with the product;

• If the battery charger is missing or damaged, only replace with one supplied by 3M.

To reduce the risks associated with electrostatic discharge (ESD) voltage, which if not avoided, could

result in damage to the meter:

• To install or change antennas, turn off the meter, install or change antennas, turn meter back on;

• Avoid touching antenna when meter is turned on

WARNING

To reduce the risks associated with environmental contamination from the EM Eye Meter CTM048 with

the lithium battery and power supply:

• At the end of service life, dispose of the EM Eye Meter CTM048 accordance with federal, state and

local requirements.

CAUTION

Overall Features

The 3M™EM Eye Meter CTM048 is capable of providing measurements for

many various parameters, which are determined by the type of sensor connected

to the EM Eye Meter CTM048. Below are the three sensors that are available

now:

• ESD Events Detection – The portable, easy-to-use EM Eye Meter CTM048

serves as a measuring instrument for most ESD signals. The EM Eye Meter

CTM048 measures the magnitude of ESD events. This meter also provides

ﬁlters to estimate the events magnitude for CDM, HDM and MM models.

• Electromagnetic Field Measurement – Enables the EM Eye Meter

CTM048 to be transformed into an EMF Meter, Power Density Meter and

EIRP Meter.

• RF Signal Sensor – The EM Eye Meter CTM048 measures the amplitude of

an RF signal.

User Features

Modular Construction

The EM Eye Meter CTM048 with the modular construction

concept can expand to different applications. With the

current design, it measures the magnitude of most ESD

events when in one of its ﬁlter modes, electromagnetic ﬁelds

(EMF), power density, effective isotropically radiated power

and radio frequency (RF).

Touch Screen to Power ON

The EM Eye Meter CTM048 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 CTM048, 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.

Easy Data Logging to Memory Card

The 3M™EM Eye Meter CTM048 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.

Package Contents

Please conﬁrm that the following accessories are included in your EM Eye

Meter CTM048 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

Precautions

• 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

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 CTM048 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 EM Eye Meter CTM048 and the sensor

heads.

3. 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.

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 CTM048, 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 CTM048. 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 CTM048 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.

Modular Assembly and Disassembly

Carefully insert the sensor head and antenna to avoid damaging the 3M™ EM

Eye Meter CTM048.

1. Position the sensor head so that the dowel pins align

with the holes.

2. With the initial head midway through, reposition it so

that it is parallel to the body.

3. Press the sensor head ﬁrmly against the body until

both surfaces are ﬂat with each other.

4. Insert and screw in the antenna making sure that it’s

not too tight or too loose. Do not use any tools other

than your hand.

Note: Antenna is not applicable for the RF Signal Sensor.

If the assembly isn’t done correctly, you may receive one of the following error

and warning messages. To correct, follow the instructions as indicated within the

message.
