Sensor
Enabled
Check this to enable the sensor assigned to this circuit (example,
for CO
2
measurement). All parameters and action buttons for a
sensor are ignored if the sensor is not enabled.
Species Name
Enter the species being measured by the sensor. This will be dis-
played in other software screens.
Zero-Cal Signal Setpoint
Target
The level, in mV, to which the sensor Zero calibration attempts to
adjust the sensor reference signal toward. For Sensor1, this param-
eter is only applicable to “Differential” Signal Type (it is ignored for
Sensor1 with “Voltage” Signal Type).
Delta (+\-) ( Sensor1 and Sensor3 screens)
The deviation, in mV, from the target level for which the sensor
Zero calibration uses to determine successful completion. For Sen-
sor1, this parameter is only applicable to “Differential” Signal Type
(it is ignored for Sensor1 with “Voltage” Signal Type). This value
should be between 50–250 after the Zero.
Signal Level at Zero-Cal
Reference ( Sensor1 screen with Differential Signal Type selected and
Sensor3 screen) The sensor Reference channel signal level, in mV, at
the completion of the Zero calibration. Record this value after the
Zero.
Differential ( Sensor1 and Sensor3 screens with Differential Signal
Type selected) The sensor Differential channel signal level, in mV,
at the completion of the Zero calibration. Record this value after
the Zero.
Voltage ( Sensor1 and Sensor3 screens with Voltage Signal Type se-
lected and Sensor2 screen) The reading (in mV) recorded by the
analyzer at the completion of the Zero calibration. This parameter
is automatically updated.
Pressure ( Sensor2 screen and Sensor3 screen with Voltage Signal Type
selected) The Measuring Cell (Sample gas) pressure (in mmHg)
recorded by the analyzer at the completion of the Zero calibration.
This parameter is automatically updated. If the
Pressure Correc-
tion Source for the sensor is Default , the Default Cell Pres is used.
