PRELIMINARY EXAMINATION Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipment. If there is any damage, notify your Dealer. Each Meter is supplied complete with: • Two Sample Cuvets and Caps* • One Transport Cap • Two 9 V Batteries • 12 VDC Transformer (HI 710005 or HI 710006) Note: Save all packing material until you are sure that the instrument functions correctly.
SPECIFICATIONS Life of the instrument Silicon Photocell 0 to 50°C (32 to 122°F); max 95% RH non-condensing Power Supply 2 x 9 V batteries / 12 to 20 VDC through voltage adapter Auto-Shut off After 10' of non-use Dimensions 230 x 165 x 70 mm (9.0 x 6.5 x 2.8") Weight 640 g (22.6 oz.) For specifications related to each single parameter (e.g. range, accuracy, etc.), refer to the related measurement section.
Given that the absorption of a compound strictly depends on the wavelength of the incident light beam, a narrow spectral bandwidth should be selected as well as a proper central wavelength to optimize measurements. The optical system of Hanna's C 99 & C 200 multiparameter photometers is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results. Four measuring channels (at four different wavelengths) allow a wide range of tests.

GUIDE TO DISPLAY CODES Note: The secondary LCD below shows a generic "P– –", whereas the meter will indicate the exact program number (e.g. in C 200, "P1" for Aluminum). This indicates that the meter is in a ready state and zeroing can be performed. Sampling in progress. This flashing prompt appears each time the meter is performing a measurement. The microprocessor is adjusting the light level, indicated by a scrolling "SIP".
Light over range. The cuvet is not inserted correctly and an eccess ambient light is reaching the detector. If the cuvet is properly inserted, then contact your dealer or the nearest Hanna Customer Service Center. The lamp is not working properly. Contact your dealer or the nearest Hanna Customer Service Center. The lamp is not working properly. Contact your dealer or the nearest Hanna Customer Service Center. This indicates that the meter has lost its configuration.
b) on sample reading: There is too much light for the sample measurement. Please check if the right sample cuvet is inserted. The sample and zero cuvet are inverted. A zero reading was not taken. Follow the instruction described in the measurement procedures for zeroing the meter. Under range. A blinking "0.00" indicates that the sample absorbs less light than the zero reference. Check the procedure and make sure that you use the same cuvet for reference (zero) and measurement.
TIPS FOR AN ACCURATE MEASUREMENT The instructions listed below should be carefully followed during testing to ensure best accuracy. • Color or suspended matter in large amounts may cause interference, therefore, these should be removed by treatment with active carbon and by prior filtration. • For a correct filling of the cuvet: the liquid in the cuvet forms a convexity on the top; the bottom of this convex- 10 mL ity must be at the same level of the 10 mL mark. • In order to measure exactly e.g. 0.
• Proper use of the powder reagent packet: (a) use scissors to open the powder packet; (b) push the edges of the packet to form a spout; (c) pour out the content of the packet. (a) (b) (c) • It is important that the sample does not contain any debris. This would corrupt the readings. • Do not let the reacted sample stand too long after reagent is added, or accuracy will be lost.

BATTERY REPLACEMENT Besides to the 12 VDC supply, these meters can also be fed by two 9V batteries. To prolong battery life, switch your meter off after use. However, the meter has an auto-shut off feature that will turn itself off after 10 minutes of non-use. A blinking "LOBAT" on the display, while a measurement is in progress, indicates low voltage and the batteries should be replaced.
