CAUTION
• To perform automatic validation, assign "Ch 0 for span calibration" of the target channel
to the contact output. ("Ch 0" is the channel number of the target channel. For more
information on contact outputs, see 5.2.3 Contact output setting
• When the gas flow channel is set to "Analyzer", assign "For Sample Switching" to the
contact output, and when the gas flow channel is set to "Sampling system", assign "System
Validation" to the contact output.
• If the gas flow channel setting is changed, be careful not to exceed or shortchange the flow
time setting.
• See 5.4.5 Automatic Validation for the operation of the contact outputs for different gas
flow channels.
Gas flow time setting
1 Tap the on the Automatic validation setting screen, scroll down, and
touch "Flow time". The flow time setting screen will appear.
2 Touch the on the flow time setting screen to display the gas for
which you want to change the setting, and then touch the item.
A keyboard dialog appears.
Please enter a numerical value.
CAUTION
• The flow time setting screen will only display the currently used Ch.
• The replacement time is the output signal hold extension time after the end of validation.
(This is valid only for the hold setting.)
• Flow time setting should be long enough to allow the concentration value to stabilize
• When a mixed gas containing multiple components is used as the calibration gas, the flow
time setting can be set to the shortest possible time of 5 seconds, since the second and
subsequent flow times are not needed by validating those components in succession. (The
assignment of components to Ch is fixed and cannot be changed.)
