DEF Chek Diesel Exhaust Flu if ester User Guide es AS ON TECHNOLOGIES Analytical Instruments AMETEK ULTRA PRECISION TECHNOLOGIES INTRODUCTION We at Reichert Analytical Instruments would like to extend our ap preciation to you for purchasing this instrument It is our mission to provide a quality product at a very competitive price and we feel this instrument will prove its value time and again to you FEATURES Sampie Wel Calibration K Liquid Crystal A Display Read Key Scale Key Battery Door The DEF Chek measures the urea content in diesel exhaust fluid DEF also referred to as AdBlue in Europe The DEF Chek provides results that are precise to 0 1 by weight SIMPLE SET UP 1 Insert the included batteries with positive side facing outward 2 Align small mark found on the battery cover with mark found on the instrument body and insert cover as shown above 3 Rotate the cover in the clock wise direction until it is in the position shown to the right CLEANING Cleaning of the measurement surface and well should be performed immediately after each sample reading Never immerse the instrument in any liquid When the measurement surface and well have been completely cleaned no residue should be present To properly clean the sample well and glass measurement surface use a mild soap and water solution or Isopropyl Alcohol followed by a distilled water rinse and t
3. easuring surface and sample For this feature to be effective however it is necessary to allow the sample to temperature equilibrate to the ambient temperature of the measuring surface Without allowing for temperature equilibration of the sample the read values will not be as accurate as they could be since the sample will be in a state of temperature and refractive index change ERROR CODES Err01 No sample present Add sample Err02 Inadequate sample Add additional sample Err03 Sample exceeds the refractive index reading range Err04 Sample temperature has not equilibrated Allow more time for temperature equilibration Err05 Excessive ambient light Cover sample well when reading Err06 Excessive ambient light Cover sample well when reading ErrO7 Positive calibration error Re calibrate with distilled water Err08 Negative calibration error Re calibrate with distilled water Err09 Poor sample condition Sample may not be able to be read Err10 Sample type may not be able to be read Err12 Index of sample is out of range of instrument Err5X For any errors in this series contact Reichert Analytical Instruments for technical assistance BATTERY CONDITION The following display examples represent either a low battery condi tion or an extremely low battery condition where the instrument will no longer operate properly In either case the batteries should be promptly replaced bc Battery condition
4. hen thoroughly dry with a soft lint and residue free cloth or a product such as Kimwipes To clean the refractometer s body use a soft cloth with a mild cleaning solution like window cleaner applied to the cloth and follow by wiping the instrument dry Reichert CLEANING PRECAUTIONS 1 Never use any harsh cleaning agents that will damage the instrument 2 Strong solvents should never be used Such chemicals will deteriorate the prism seal and attack individual component parts of the instrument which will adversely affect or destroy the instrument CALIBRATION 1 Be sure that the measuring surface and well are clean as outlined under the Cleaning section 2 Apply distilled water to the measurement surface 3 Allow time for the distilled water sample to temperature equilibrate to that of the instrument 4 Press and hold the CAL key until CAL is displayed While still holding the CAL key press the READ key and then release both keys 5 A series of dashed lines will appear and successful calibration will be indicated when the word END is displayed CAUTION 1 Due to the nature of any automotive fluids to avoid possible injury Reichert recommends that safety glasses and gloves be worn when testing any sample type SAMPLE ANALYSIS Before analyzing a sample it should be noted that to attain the greatest accuracy the refractometer should be calibrated at the same temperature as the envirnoment
5. that it will be used in As an example if the environment that the instrument is being used in changes by five degrees then the instrument should be re calibrated 1 Inspect the glass measuring surface and well to be sure that there is no residue remaining from a previous sample analysis If the measuring surface and well does not appear to be clean then refer to the cleaning section of this user guide before proceeding 2 Extract the sample to be tested and apply adequate sample to the sample well to completely cover the glass measuring surface Minimum sample size is 0 3 mL 3 Allow the sample time to reach the same temperature as the instrument Failure to do so will result in inaccurate measurement 4 Press the READ key and note the displayed value DISPLAYING ACTUAL TEMPERATURE To display the temperature at the measuring surface momentarily press the CAL button while the sample value is displayed AUTOMATIC TEMPERATURE COMPENSATION All Reichert refractometers are automatically temperature compensated assuring extremely accurate results Automatic temperature compensation corrects readings over a range of temperatures As an example samples taken within the working temperature range of the instrument are corrected to a reference temperature of 68 F 20 C Temperature compensation is essential because refractive index varies inversely with temperature This feature is used in lieu of temperature control of the m
