CAUTION
• To execute auto-calibration, assign "Chx for span calibration" of the target channel to the
contact output. ("x" is the channel number of the target channel.) For more information on
contact output, refer to 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
Calibration" to the contact output.
• If the gas flow channel setting is changed, watch out for excess or deficient flow time setting.
• Even during manual calibration, the system operates according to the gas flow channel and
displacement time set here
• For the operation of the contact output resulting from different gas flow channels, refer to
5.4.1 Manual Zero Calibration, 5.4.2 Manual span calibration and 5.4.3 Automatic
calibration.
• If an external oxygen analyzer and its channel is the target channel, set the following.
• Assign "Chx for span calibration" to the contact output for calibration indication.
• Assign "O
2
meter input" to the contact input to receive calibration completion. (See 5.2.4
Contact input setting for more information on contact inputs.
• The replacement time to wait for the switchover from the calibration gas to the measurement
gas is set by the product, so set the replacement time of the external oxygen analyzer
(named "stability time" in the ZR802G) to 0 minutes and 0 seconds. The displacement time
of the external oxygen analyzer (named "stability time" in the ZR802G) should be set to 0
minutes and 0 seconds.
Gas flow time setting
(1) On Auto calibration setting screen, tap to scroll down and tap [Flow
time]. Flow time setting screen is displayed.
(2) Tap to display the item to set. Tap the item to set. A keyboard
dialog appears
