Failure alarm down-scale: Output status at CPU failure and

Failure alarm up-scale: Output status at CPU failure and
hardware error is 21.0 mA or more (*12)
*1 For the horizontally installed probe whose insertion length is 2.5 m or more, use the Probe Protector. Be sure to specify
ZO21R-L-200-
□. Specify the ange sufx code either -C or -K.
*2 The thickness of the ange depends on its dimensions.
*3 Inconel probe bolts and U shape pipe are used. Use this option for high temperature use (ranging from 600 to 700°C).
*4 For humidity measurements, be sure to specify /HS options. Pressure compensation of reference gas can not be selected.
*5 Specify either /CV or /SV option code.
*6 Not used with the high temperature humidity analyzer.
*7 Specify either /SCT or /PT option code.
*8 No need to specify the option codes, /CV and /SV, since the check valves are provided with the Automatic Calibration Unit.
Automatic calibration cannot be used when natural convection is selected as reference air.
*9 Sun shield hood is still effective even if scratched. Hood is necessary for outdoor installation out of sun shield roof.
*10 Recommended if sample gas contains corrosive gas like chlorine.
*11 Piping for reference gas must be installed to supply reference gas constantly at a speci ed  ow rate.
*12 Output signal limits: 3.8 to 20.5 mA. Specify either /C2 or /C3 option code.
