While a contact signal is on, neither semi-automatic nor automatic calibrations
can be made.
Measuring range change While contact input is on, the analog output range is switched to 0-25% O

.
Calibration start If a contact signal is applied, semi-automatic calibration starts (only if the semi-
automatic or automatic mode has been setup). Contact signal must be applied
for at least one second. Even though a continuous contact signal is applied, a
second calibration cannot be made. If you want to make a second calibration,
turn the contact signal off and then back on.
Unburnt gas detection If a contact signal is on, the heater power will be switched off. (An one-to
11-second time interval single-output signal is available as a contact signal.) If
this operation starts, the sensor temperature decreases and an error occurs. To
restore it to normal, turn the power off and then back on, or reset the analyzer.
