Instruction Manual MULTIPARAMETER ION SPECIFIC METERS Manufacturers since 1978 These Instruments are in Compliance with the CE Directives
Dear Customer, Thank you for choosing a Hanna product. Please read this instruction manual carefully before using the meter. This manual will provide you with the necessary information for the correct use of the instrument. If you need additional technical information, do not hesitate to e-mail us at tech@hannainst.com. These instruments are in compliance directives EN 50081-1 and EN 50082-1. with TABLE OF CONTENTS PRELIMINARY EXAMINATION ....................................................................
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 Ion Specific Meter is supplied complete with: • 9V Battery • Two Sample Cuvets and Caps* • One Transport Cap Note: Save all packing material until you are sure that the instrument functions correctly. Any defective item must be returned in its original packing with the supplied accessories.
The quantity of radiation absorbed is given by the Lambert-Beer Law: log Io/I = ελ c d Where log Io/I = Absorbance (A) ελ = molar extinction coefficient of the substance at wavelength λ c = molar concentration of the substance d = optical distance light travels through sample Therefore, the concentration "c" can be calculated from the color intensity of the substance determined by the emitted radiation I, as the other factors are known.
It is recommended not to touch the cuvet walls with hands. Furthermore, in order to maintain the same conditions during the zeroing and the measuring phases, it is necessary to close the cuvet to prevent any contamination. DISPLAY CODE GUIDE V This indicates that the meter is in a ready state and zeroing can be performed. Sampling in Progress. This prompt appears each time the meter is performing a measurement. This indicates that the meter is in a zeroed state and measurement can be performed.
TIPS FOR AN ACCURATE MEASUREMENT The instruction listed below should be carefully followed during testing to ensure best accuracy. • Do not let the test sample stand too long after reagent is added or accuracy will be lost. • Whenever the cuvet is placed into the measurement cell, it must be completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI 731318 or a lint-free cloth prior to insertion. • It is important that the sample does not contain any debris. This would corrupt the readings.

BATTERY REPLACEMENT 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 "V" on the LCD indicates low voltage and the battery should be replaced. If the battery is not replaced immediately, in order to prevent erroneous readings due to low voltage "-BA-" is displayed soon afterwards. At this point, the meter will completely lockup and will not allow any commands and the display will go blank.
