General Information

With the CD mon Luminance/ Illuminance Meter, you can

perform the tests required according to DIN 6868 Part 157:

“Acceptance Testing of Image Display Devices” as well as the

corresponding constancy tests.

The device can also be used for testing viewing devices in

accordance with DIN 6856 Part 1 and 2.

The device fulfils the requirements set forth therein for a

luminance/illuminance meter according to DIN 5032 Class B.

By using the spacer leg included with the CD mon device, you

can include reflected ambient light in the measurements.

Contact measurement is also possible.

Two integrated lasers enable you to precisely aim the device

at the measurement point. The laser beams are aligned in

such a way that the laser points overlap each other when the

device is held at the proper distance (ca. 50 cm) from the

monitor.

Scope of Delivery

Please check to be sure the product shipment is

complete. If the shipment is incomplete, please contact

the dealer from whom you purchased the product.

The CD mon product shipment consists of the following

components:

•CD mon measurement device

•5 Volt USB rechargeable battery charger

•USB data / recharger cable

•3.7 V LiPo rechargeable battery (mounted in the device)

•Driver CD for connection to the USB port

•1 protective cap

•Spacer leg

•Contact tube

•Instruction Manual

Laser Classification

The lasers used in the CD mon device to target the

measurement point are classified in Laser Class 2 according

to VDE 0837 and IEC 825.

The permissible radiated power of a

continuously operated laser of this class is

limited to a maximum of 1 milliwatt (1 mW).

The wink reflex ensures adequate eye

protection. That means that eye injuries are

only possible if someone deliberately looks

into the laser beam for several seconds while

suppressing the wink reflex.

Laser Radiation

Wavelength - 400-700 nm.

Don’t look into the laser

beam!

Laser Class 2

Handling and Safety Information for the Lithium Polymer

(LiPo) Rechargeable Battery!

IMPORTANT! Please read the following section before

using the device for the first time!

General Information

A modern LiPo (“LiPo” = lithium polymer) rechargeable battery is used

in the PEHAMED CD mon device. These rechargeable batteries not

only have a significantly higher capacity than NiMH and NiCd

rechargeable batteries, they are also much lighter in weight. These

advantages make this type of rechargeable battery particularly suited

for use in highly mobile measurement devices such as the CD mon.

WARNING! Despite the fact that we only use highest quality, brand

name LiPo rechargeable batteries in the PEHAMED CD mon device, a

slight residual risk of the formation of smoke, fire, serious personal injury

or property damage always remains.

LiPo cells and LiPo rechargeable battery packs can explode or catch

fire if they are improperly handled or damaged.

For these reasons, only trained users may use, recharge and discharge

LiPo rechargeable batteries. Users must inform themselves about

measures to be taken in case a hazardous situation develops.

By purchasing the PEHAMED CD mon device, buyer assumes full

responsibility for all risks that may arise from the use, operation,

charging and discharging of the LiPo rechargeable battery.

Exclusion of Liability

PEHAMED cannot control and ensure the proper charging and use of

the LiPo rechargeable battery in the CD mon device, and therefore

cannot be held liable for possible accidents, personal injuries or

property damage that could result from the use of this product with

LiPo rechargeable battery.

First Charging

At the time of shipment, the LiPo rechargeable battery installed in the

CD mon device has been factory loaded to ca. 50% of its capacity.

For that reason, please recharge the LiPo rechargeable battery to full

capacity before using the unit.

New LiPo rechargeable batteries require up to twelve or more char-

ging / discharging cycles before they provide optimum performance.

Charging the Rechargeable Battery

Use the USB cable included in the delivery to charge the rechargeable

battery of the PEHAMED CD mon device. The charging voltage can be

supplied either directly from a computer USB socket or via the

pluggable power supply with USB socket supplied with the device.

NOTE! Only use the USB cable and pluggable power supply supplied

by PEHAMED that were specially designed for use with the LiPo

rechargeable batteries utilized in the CD mon device!

If you use other pluggable power supplies or USB cables, this could

damage the device and/or the LiPo rechargeable battery and cause

smoke or fire to develop!

If you use a different USB cable or pluggable power supply, this will

immediately void the CD mon guarantee!

LiPo rechargeable batteries are particularly sensitive against total

discharge and overcharging. This can immediately and permanently

damage such batteries. For this reason, the LiPo rechargeable battery

integrated in the CD mon device is equipped with a special electronic

protection module. This protection module prevents total discharging

or overcharging of the LiPo cells.

Always charge such rechargeable batteries only on a fireproof surface

and far away from combustible materials! Never recharge the device

on inflammable materials.

Always store a chemical fire extinguisher nearby in case of fire.

Never leave the CD mon device unattended during the recharging

process so that you can react quickly in case a problem occurs.

Before starting the recharging process, always first plug the pluggable

power supply into the wall socket or the “wide” USB plug into the USB

socket of the computer. Only after doing so, plug the mini USB plug into

the charging socket of the CD mon device.

Before disconnecting the device from the power supply, always first

remove the mini USB plug from the device.

During the charging process of the switched-off device, the display will

show the message “CHARGING”. In case you recharge the unit while

making measurements, the display will show the info “chrg” in the

lower right section next to the battery symbol.

As soon as the CD mon LiPo rechargeable battery has been

completely recharged, the device electronics will recognize this, the

recharging process will be automatically switched off and the

messages will disappear from the display.

Economic Operation

Avoid regularly totally discharging the LiPo rechargeable battery.

Frequent partial discharges followed by complete recharging are

easier on the rechargeable battery than routine complete

discharging.

LiPo rechargeable batteries do not have a memory effect and

therefore can and should be fully recharged regardless of the battery

charge level. In doing so, we do not recommend discharging the

rechargeable battery prior to recharging. The usable service life of

rechargeable batteries is usually reduced by exposure to excessively

high temperatures (for example, by storing the device in a hot

automobile in summer) and by total discharging.

Fire Extinguishing Information

If a LiPo rechargeable battery should catch fire, you should extinguish

the fire using fire extinguishing powder, sand or similar fire extinguishing

material.

Never use water to extinguish the fire, as it can react with the lithium

contained in the rechargeable battery! This would then cause an

explosion like when you try to extinguish a grease fire with water.

Disposal / German Battery Decree

Batteries and rechargeable batteries must not be disposed of with

household waste!

According to German statutory regulations, the end user is obligated

to return all used batteries and rechargeable batteries.

For that reason, you can return the rechargeable batteries to

PEHAMED or drop them off directly at our facility. You can also return

used rechargeable batteries, free of charge, to the public collection

points in the communities and at local authorities.

German Waste Electrical and Electronic Equipment Ordinance (EAR)

Once the CD mon device has reached the end of its useful service life

and can no longer be used, PEHAMED and/or your local public waste

disposal authority would be happy to provide you with information on

how to properly dispose of the device.

As is the case with all other kinds of electronic products, you should

never dispose of the CD mon device with household waste. You can

return your old, used electronic products at no charge to PEHAMED or

the public collection points of your community.

In accordance with the EAR Ordinance, PEHAMED is a registered

manufacturer with WEEE Registration No. DE 94334983.
