    1.1.2 System Operation 系统运行 The Mk8 E.G.A. samples the combustion gases via the stack mounted sampling probe (purchased separately from the analyser). The exhaust gases are drawn from the stack by a pump mounted internally within the analyser. Only the supplied sample tubing should be used between the sampling probe and analyser.
  • Page 10 Note: The E.G.A. needs to vent to atmosphere via the drain solenoid on the bottom; this is also where the E.G.A. performs its air calibrations. Care should be taken to ensure the outlet is not restricted or that contamination from exhaust gas occurs. 注：尾气分析仪需要通过底部的排放电磁阀将废气排放到大气中，此时尾气分析仪需要执行空 气校准操作。应注意出口没有任何堵塞且废气不会造成污染。 Mk8 E.G.A.
