The user manual provides instructions for operating the instrument, including maintenance of its flow cell and programming of various analytical techniques. Medical EXPO Core Manual Content & Operations Startup & Main Menu
: The analyzer features a menu-driven interface accessible via a tactile membrane keyboard or touch screen, depending on the specific model version. Key menu options typically include Concentration, Absorbance, Utilities, Configuration, and Programming. Aspiration & Fluidics
: It uses a continuous flow system with an integrated peristaltic pump. Sipping volumes can be programmed from Reading Modes
: The analyzer supports several measurement methods, including: Fixed Time Differential Mode Quality Control (QC)
: The system can store the last 31 results for each test and generate Levey-Jennings charts Westgard rules for monitoring precision. Medical EXPO Essential Maintenance Tips Cleaning the Flow Cell
: It is critical to wash the flow cell with distilled water before use and after every individual test to prevent carry-over. Shutdown Procedure
: To safely shut down, first clean the aspiration system with distilled water, then navigate to the menu's "shutdown" button before physically turning off the machine. LED Advantage biosystems bts 350 user manual
: The LED light source is designed to be maintenance-free with a virtually unlimited lifetime, reducing frequent bulb replacements common in older photometers. Lab Supply Group SEMI-AUTOMATIC ANALYZER BTS-350 - BioSystems S.A.
