Since Abacus junior / Abacus junior vet / Abacus junior B haveso much common characteristics, we issue a common Service Manualcovering all instruments. Information herein applies for allinstruments unless otherwise noted. To be well up in theinstruments, please read this manual carefully to have theknowledge for servicing the instruments perfectly and avoid extracosts and wasting precious time. In this manual, we are using thefollowing conventions:

This Abacus junior / Abacus junior vet / Abacus junior B ServiceManual contains the functional descriptions of all analyzers,operation of the fluidic systems, adjustments and settings, andvery important information for the Service Personnel about theservice operations and possible problems.

Abacus junior / Abacus junior vet / Abacus junior B hematologyanalyzers are fully automated cell counters for in vitro diagnosticuse. The compact instruments were developed for small clinics,point-of-cares and vet offices.

The integrated software controls the instrument operations,displays, stores, recalls data, and allows the user to perform QCand calibration procedures and modify the user settings. Thesoftware version number can be read out from the Device Informationor from the Self test submenu. Software is absolutely Plug andPlay, it can read out and detect the type and the serial number ofthe instrument, therefore it will run the correct program for thehardware, without any user or service help. Every Abacus junior /Abacus junior vet software version is upgradeable (using a floppydisk) by the latest program developed by DIATRON. Software upgradeof Abacus Junior B requires a special SW downloading application(more about this in Section 9.3) running on a separate PC, astandard null-modem serial cable with 9-pin connector, and anupgrade SW from web page of DIATRON:

An abacus is a mathematical toy that consists of either wooden, plastic, or silicone compartments in the form of beads or push pops. They are helpful in number and symbol recognition, memory building, addition, subtraction, multiplication, division, computing, etc. Some models have columns with wooden or plastic beads that the child can easily move and perform any of the basic mathematical equations. Some may have numbers printed separately on blocks below and mathematical symbols like plus, minus, divide, equal to, multiply, etc. Such toys also help in creativity, imagination, and problem-solving. So if you want to make learning more fun for your child, choose an abacus that will help them improve in basic mathematics. The silicone push pop types are soft, non-toxic, unbreakable, lightweight, and safe. They are simple fidget types that can especially help children with special needs. The popping action and sound can help soothe and relieve stress considerably. They are also available in different attractive colours and shapes like heart, butterfly, dinosaur, unicorn, popsicle, ice cream, etc. Shop online and buy abacus for kids from brands like CrazyCrafts, Little Genius Abacus, The Mechanic, A A Mart, triple ess toy, etc. Order from your home and have it delivered to your doorstep.
