6.1.2 Manual Range Mode
The analysis range for the measured component can be switched manually as follows:
1.(1) Select “MR” as range switch mode, and then press the ENT key.
2.Using the UP/DOWN keys, move the cursor to the desired range selection. The highlighted arrow indicates the currently selectable range.
3.Select it by pressing the ENT key, and analysis will be carried out in that range.
Note: If “RR” or “AR” is selected as range switch mode, this operation cannot be performed.
The ranges for O2 correction value,O2 correction average value, and O2 average value are automatically switched according to the instantaneous value range switch settings. (Same as for “RR” or “AR”.)
To return to the previous screen, press the ESC key. If ESC is pressed in the middle of an entry or before the ENT key was pressed to accept a setting, it will reject the current selection and return you the display to the previous screen without making the changes .
6.1.3 Range Identification Contacts
The contacts for range identification on each channel are closed when Range 1 is active, and open when Range 2 is active.
If the measurement value is held by a remote contact input or during calibration and range switch conditions are met, the contact status will change only after the hold condition is removed.
