Settings and Calibration

 

 

 

But during a manual calibration the screen displays the process of calibration, therefore a “Hold ON” message will not displayed even if the output signal is held, however the screen will display the hold extending time.

If the calibration is cancelled after the calibration gas has been supplied, the holding extending time will be performed in either of manual or auto calibration operation.

You can select the hold value from the value immediately before entering output hold. The choices are “current” or an arbitrary value input using “setting”.

Use the procedures shown below for adjusting these settings.

1.From the “Parameter setting” screen that appears, select “Output Hold”. Highlight either “ON” or “OFF” using the UP or DOWN key and then press ENT to select it and return to (1).

2.When ON/OFF is highlighted, press the SIDE key. Toggle between “Current” or “Setting” using the UP/DOWN keys and then press ENT when the desired selection is highlighted.

3.Pressing ENT when “Current” is selected will hold the value immediately before the hold was initiated and return the highlight to (1).

Pressing the ENT key while “Setting” is selected will bring up the

parameter hold screen where an arbitrary hold value can be set.
