Check the mechanical viscosity-based detector for obstructions. Run control samples to ensure precision. 3.3. Troubleshooting
Monitored in seconds, % activity, or INR. Used for extrinsic pathway screening and oral anticoagulant therapy (Warfarin) monitoring.
Ignoring these steps can lead to inconsistent reagent dispensing and volumetric errors.

The incubation block is outside the 37°C threshold. Wait for the block to stabilize. Ensure the analyzer is away from air conditioning vents.
. Unlike optical systems that can be fooled by "difficult" samples, this mechanical method is: Interference-Free
Insert the pipette tip into the cuvette and immediately dispense the reagent. Simultaneously press the corresponding channel start button (or utilize the auto-start pipette linkage if equipped) to activate the internal stopwatch. Troubleshooting Monitored in seconds, % activity, or INR
ST Art 4 Reference Manual | PDF | Electromagnetic Interference
The manual includes timing diagrams that show exactly when the needle dispenses reagent versus when the photometric reading begins.
The heart of the STart 4 is the . Unlike optical systems that can be affected by lipemic, icteric, or hemolyzed samples, the STart 4 uses a mechanical approach: Are you troubleshooting a or mechanical failure on
Every time you flip the switch, the unit performs a series of automated tests: RAM & EPROM Tests : Checking the internal brain of the machine. Serial Line Test : Verifying the electronics of the pipette header. Display Check : Ensuring all 40 characters on the LCD are legible. 2. The Pipette Header: Your Most Critical Link The manual highlights the importance of the electronically-linked multiple pipettor
From a regulatory perspective, your lab’s inspector will ask to see the manual. According to CLSI (Clinical and Laboratory Standards Institute) guidelines, the manufacturer’s instructions must be “readily accessible” to all operators. Furthermore, any deviation from the manual’s procedures must be validated in-house.
