Select Gas to be Calibrated All, Oxygen, Combustibles, Methane
Recovery Duration Dene a time period for the system to recover from
reading calibration gas values to reading process
gases.
Calibration Gas Values Enter the calibration gas values to match the span and
zero calibration gas cylinders you will use to calibrate
or verify your system.
A calibration cannot be performed if there is a Fail alarm active except
in the case of when the alarm is triggered by low ow. Calibration can
start or continue during Low Sample Flow alarm status.
The span gas is the high calibration gas. The zero gas is the low cali-
bration gas.
All gases selected under Sensor Conguration (O
2
, combustibles, methane)
require calibration but do not have to be calibrated at the same time. However,
calibration will always occur in the same sequence.
1. O
2
Span
2. Zero
3. Combustibles Span
4. Methane Span
For example if the sensor is congured for oxygen, combustibles and methane
and you are skipping the O
2
calibration, the order would be as follows:
1. Zero Calibration
2. Combustible Span Calibration
3. Methane Span Calibration
To cancel a calibration at any time, select Abort and press ENTER/
MENU.
