CAUTION
• Measurement range switching function by an external contact input is available for analog
output1 only.
• When making a semi-automatic calibration, be sure to set the semi-automatic or automatic
mode using the Calibration setup display.
• When carrying out “Blow back,” be sure to set “Blow back” in the output contact setup.
• When the combustible gas detection signal is sent to the contact input, the converter will cut
the power supply to the heater of the detector. As a result, the heater temperature becomes
low and Error 1 or Error 2 happens.
