Lamp ON/OFF: A selection to toggle the sensor lamp
on and off.
Meas Signal: A selection to start an automatic signal
measurement sequence. This sequence measures
sensor lamp signal levels.
Meas Zero: A selection to start an automatic zeroing
measurement sequence.
Meas Gas: A selection to start an automatic gas
measurement sequence. This sequence first
performs the zeroing measurement. Then it
measures the CO
2
concentration of the sample of
arbitrary gas aspirated from the catheter port.
Record Data: A selection to print out the shown
service data to the device defined in the ...Service -
Record Data menu.
TONO
Calib gain; CO
2
measurement gain factor that is set
in calibration.
Lamp on current; sensor lamp current when lit.
Lamp off current; sensor lamp current when off.
Block temp; sensor temperature [°C] (in degrees centigrade).
Detector offset; CO
2
detector offset voltage.
Lamp status; displays whether the sensor lamp is on or off.
CO2 AD; signal from CO
2
sensor thermopile (AD counts).
CO2 signal; thermopile signal maximum – minimum when the lamp is blinking (AD counts).
CO2 zero; thermopile signal maximum - minimum during sensor zeroing when the lamp is blinking (AD counts).
CO2 absorbance; calculated light absorbance during CO
2
measurement.
CO2 concentration; CO
2
concentration (%) in sensor (does not include compensations related to catheter
measurement).
MEAS TEMP; CO
2
sensor temperature during signal measurement [°C].
MEAS PRESS; CO
2
sensor pressure during signal measurement [mbar].
ZERO TEMP; CO
2
sensor temperature during zeroing measurement [°C].
ZERO PRESS; CO
2
sensor pressure during zeroing measurement [mbar].
