Vernier Go Direct Colorimeter Quick Start Manual page 3

Make sure to place a cuvette in the Colorimeter so the path of the light source
l
travels through the clear sides of the cuvette. An arrow to the right of the
cuvette slot shows the light path.
For best results, use one cuvette to make all your measurements for a given
l
experiment.
If you calibrate a Colorimeter and then change the wavelength, calibrate the
l
Colorimeter again to ensure the proper identification of the new wavelength.
For best results, a sample's absorbance or transmittance values should fall within
these ranges:
percent transmittance:10–90%
absorbance: 0.05–1.0
Beer's law experiment results begin to lose their linearity at absorbance values
above 1.0 (percent transmittance values less than 10%). If you have a solution that
transmits such a low level of light, consider diluting the solution so that it falls
within this range.

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These
limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

FCC Caution
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference and
(2) this device must accept any interference received, including interference that may cause undesired operation
RF Exposure Warning
The equipment complies with RF exposure limits set forth for an uncontrolled environment. The antenna(s) used for this transmitter must not
be co-located or operating in conjunction with any other antenna or transmitter. You are cautioned that changes or modifications not
expressly approved by the party responsible for compliance could void your authority to operate the equipment.
IC Statement
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operation of the device.
Industry Canada - Class B This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set
out in the interference-causing equipment standard entitled "Digital Apparatus," ICES-003 of Industry Canada. Operation is subject to the
following two conditions: (1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operation of the device.
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically
radiated power (e.i.r.p.) is not more than that permitted for successful communication.
RF exposure warning: The equipment complies with RF exposure limits set forth for an uncontrolled environment. The antenna(s) used for
this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est
autorisée aux deux conditions suivantes :
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'appareil doit accepter tout interférence radioélectrique, même si cela résulte à un brouillage susceptible d'en compromettre le
fonctionnement.
Cet appareil numérique respecte les limites de bruits radioélectriques applicables aux appareils numériques de Classe B prescrites dans la
norme sur le matériel interférant-brouilleur: "Appareils Numériques," NMB-003 édictée par industrie Canada. L'utilisation est soumise aux
deux conditions suivantes:
(1) cet appareil ne peut causer d'interférences, et
(2) cet appareil doit accepter toutes interférences, y comprises celles susceptibles de provoquer un disfonctionnement du dispositif.
Afin de réduire les interférences radio potentielles pour les autres utilisateurs, le type d'antenne et son gain doivent être choisie de telle
façon que l'équivalent de puissance isotrope émis (e.i.r.p) n'est pas plus grand que celui permis pour une communication établie.
Avertissement d'exposition RF: L'équipement est conforme aux limites d'exposition aux RF établies pour un environnement non
supervisé. L'antenne (s) utilisée pour ce transmetteur ne doit pas être jumelés ou fonctionner en conjonction avec toute autre antenne ou
transmetteur.
Note: This product is a sensitive measurement device. For best results, use the cables that were provided. Keep the device away from
electromagnetic noise sources, such as microwaves, monitors, electric motors, and appliances.
