3.7 Calibration
3.7.1 Zero Calibration
The zero calibration is used for zero point adjustment. A suitable
zero calibration gas is described in Section 2.5.5
Preparation of
Calibration Gas.
To zero calibrate the analyzer:
1.
Press the ZERO key on the Measurement screen to
display the Manual Zero Calibration screen.
2.
Select the channel to be calibrated by pressing the UP or
DOWN key. After selection, press the ENT key, and zero
gas will be supplied.
Note: For channels that are set to “both” in the “Zero Calibration”
of the Calibration Setting mode, the zero calibrations are
carried out at the same time.
3. Wait until the display has stabilized with the zero gas
flowing. After stabilization, press the ENT key. At this
point, the zero calibration on the range indicated by the
cursor is carried out.
Note: If the selected channel was set for autoranging “AR” (see
Section 3.5.1 Switch Ranges. the cursor automatically
moves to the range selected in “Setting of Auto Calibration
Component/ Range” (Section 3.5.2.4), and calibration is
carried out within that range.
