However, because of the corrosive and extreme conditions under which the instrument must operate, some difficulties may still be encountered. The procedures for resolving many of these situations are discussed in this chapter. If the information provided in this chapter is not sufficient, please consult Panametrics for assistance. FGA 300H(X)的设计是为了克服与监测烟道气体相关的很多常见问题。然而，由于仪器必须操作在腐蚀和极端的条件下，所以可能仍然会遇到一些困难。本章讨论解决许多这些情况的方法。如果本章中提供的资料不够充分，请咨询Panametrics援助。 The FGA 300H(X) analyzer has two sets of error indicators that can occur: ? oxygen measurement errors ? combustibles measurement errors FGA 300H(X)分析仪具有两套可能会出现的错误指示： ?氧气测量误差 ?易燃的测量误差 Each error indicator appears on the corresponding readout of the 300D Display Console. Thus, if there is an oxygen measurement error, the error indicator will appear on the oxygen readout. Refer to Table 5-1 on 2 to troubleshoot the FGA 300H(X) analyzer. 每个错误指标出现在300D显示控制台的相应读出器上。因此，如果有氧气测量误差，误差指示会出现在氧气读出器上。 参考5-2页上的表5-1，检修FGA 300H(X)分析仪。 !WARNING! To ensure safe operation of the FGA 300H(X), it must be installed and operated as described in this manual. In addition, be sure to follow all applicable local safety codes and regulations for installing electrical equipment. All procedures should be performe
