In next chapter, there will be instruction of how to do setting.The calibration of the flowmeter have been finished in manufacture’s lab before delivery, includingtemperature and pressure calibration if required and the setting of high-limit and low-limit of 4~20mAstimulation output. Thus customers do not to set any more.5 SettingNote: Every TGF450 thermal mass flowmeters has been set according to requirement beforedelivery, please do not change setting unless it is necessary and under correct instruction!TGF450 thermal mass flowmeter have digital setting and code setting. Use code setting to setparameters such as damping and output signal. Use digital setting to set parameters related to a number,such as pipe size, flow range, factor.5.1 How to set5.1.1 Code settingUnder working status, to enter code setting, please hold “Enter button” then press “U-D button” at thesame time.
