Teledyne Analytical Instruments 63
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.
