The manual also highlights a "Shutdown" procedure to turn off the device safely and preserve its components.
Use the integrated QC software module to view Levy-Jennings charts.
Apply Westgard rules to detect systematic errors (shifts and trends) or random errors. Do not report patient results if control values breach the ±2plus or minus 2 standard deviation ( SDcap S cap D ) thresholds. 6. Preventative Maintenance Schedule biosystems bts 350 user manual
According to standard operating procedures (which would be found in your manual), you should never just turn the unit on and walk away.
The absorbance or concentration result will display on the screen and print automatically if an internal or external printer is connected. 5. Maintenance and Cleaning Procedures
If your unit has a pump:
The BioSystems BTS-350 is a semi-automated clinical chemistry analyzer used globally in medical laboratories. It balances advanced optics with a durable design, making it ideal for small to medium-sized labs, clinics, and emergency departments.
Comprehensive Guide to the BioSystems BTS-350 Semi-Automatic Analyzer Light Emitting Diodes (LEDs) provide lower power consumption
: Inspect the internal peristaltic pump tubing for wear, flat spots, or loss of elasticity. Replace the tubing if it shows signs of degradation to maintain accurate volume delivery. 8. Troubleshooting Common Error Codes Observation / Error Potential Cause Recommended Action Absorbance out of range Bubbles in the flow cell; contaminated reagents. Flush flow cell with water; check reagents for turbidity. Unstable readings Temperature fluctuations; lamp block dirty. Wait for complete stabilization; clean flow cell. Aspiration failure Clogged probe; split or loose peristaltic pump tubing. Clean probe with a fine wire; replace pump tubing. Printer not feeding Paper roll inserted backward; empty roll. Reorient paper roll; install fresh thermal paper. Filter wheel error Mechanical obstruction; sensor malfunction.
Properly setting up the analyzer is crucial for reliable performance. According to the manual, the installation requires careful unpacking and preparation.
The BTS 350 is a compact, durable gas monitor typically configured to detect up to four gases simultaneously. It is designed to withstand the harsh conditions of industrial environments—think water treatment plants, petrochemical refineries, and underground utilities.
| Display | Meaning | Action | |---------|---------|--------| | FAULT | Sensor failure or missing | Remove/replace sensor | | CAL ERR | Calibration failed | Repeat cal with fresh gas | | BATT LOW | Battery voltage low | Replace batteries immediately |
The analyzer features a tactile membrane keyboard with clearly labeled keys and a large, backlit graphic LCD (320x240 pixels) for viewing menus and results. The front panel includes an indicator light to show the instrument's status. A key component is the , which manually activates the peristaltic pump to aspirate fluids during sample loading.

Before the first run, the manual instructs users to perform a "Wash" cycle with distilled water to clear any air bubbles or debris from the flow cell. 3. Navigating the Interface
The BTS-350 is designed for low maintenance, but regular care is essential for peak performance and longevity. The service manual details the need for trained personnel to perform deeper checks, but the user manual outlines tasks for daily upkeep.
