- Page 4 Operating Instructions Model L3P Sonic Sifter Separator Installation Place the Model L3P Sonic Sifter Separator on a level surface for operation. Observe the ambient temperature and humidity guidelines outlined in the specification section. Electrical Connection Plug the power cord into the socket in the rear of the unit and then into the appropriate power source as outlined in the specification section.
- Page 5 Amplitude Control The Amplitude Control adjusts the amount of “lift” applied to the powder in the sieve stack. The density of the particles, the presence of electrostatic or other physical bonds, and the percentage of fine material in the sample determine the amount of lift required. Digital Timer/Clock The timer controls the cycle time of the sieving operation, as well as functioning as a 24-hour clock.
- Page 6 The clock mode is a 12-hour with an am/pm display element. When the clock is being displayed and the clock is in the pm time frame, the decimal point of number 1-seven segment will be ON. Once the user has achieved the proper clock value, they need to exit the clock set mode by pressing and holding the button [SET/DISPLAY] for 1 second.

A good rule of thumb is to use the smallest sample size possible that is still representative of the lot from which it was extracted.
- Page 10 Inserting the Stack Assembly Slide the stack assembly into the test chamber with the column arms locked. The stack assembly is stopped at the top by two tabs on the driver support plate. On the test chamber table, you will notice two rivets that will limit how far the stack can be placed inside the chamber.
- Page 11 CARE OF ADVANTECH MODEL L3P SONIC SIFTER SEPARATOR AND ACCESSORIES The Advantech Model L3P Sonic Sifter Separator and Accessories will perform satisfactorily for many years if the following basic care instructions are observed: Cleaning the Sieves and Stack Assembly Parts For best results, stack assembly components and sieves should be cleaned in an ultrasonic cleaner of 150 watts or less.
- Page 12 CAUTIONS U.S. Standard Sieve Series: Improper handling can cause serious damage to the sieve openings and accelerate sieve failure. DO NOT remove particles clogging sieve openings • with a needle or other sharp object. DO NOT • use compressed air to clean the sieves or dislodge trapped particles.

CHAPTER 2 USES, LIMITATIONS AND ADVANTAGES Harold Heywood wrote "I often refer to sieving as the 'Cinderella' of particle size analysis methods; it does most of the hard work and gets little consideration." There are numerous reasons for the selection of high quality testing sieves as a first choice in particle size analysis work. - Page 20 and the test is run for 30 minutes, the components and each other with strong probability of larger-than-nominal particles electrostatic charges.
