Question 1: Host communication fails and cannot be connected
Measures: Follow the prescribed power-on sequence (turn on the computer-turn on the instrument and turn on the workstation) and try again, check whether the serial port cable is connected, and reinstall the operating system or instrument software
Question 2: A crash occurred during the measurement process
Measures: Uninstall or close the software that may interfere with the workstation (such as anti-virus software), replace the element lights or not plug in the lights for testing
Question 3: The instrument has no signal
Measures: Check whether the element lamp is on, whether the energy reflection of the lamp is normal, determine whether it is a circuit problem or a sampling system problem, check whether the pipeline is connected correctly, whether the sample or reducing agent is sucked into the reaction block, and whether the reaction is normal (a lot of bubbles are generated) ), waste discharge tube leaks, the reagent is available, the accuracy of the concentration and the like
Problem 4: The signal is unstable
Measures: The instrument warm-up time is not enough, extend the warm-up time, check whether the sampling system is blocked causing abnormal sampling, whether the pump tube is deformed and needs to be replaced, whether the air flow is accurate, and whether the instrument condition selection setting is appropriate
Question 5: Blank or high standard value
Measures: Generally, reagents, utensils or instruments themselves are contaminated, especially mercury, which is prone to memory effects and pollution
